Boilers, inspections and compliance
We base that on boiler duty, condition, shutdown windows and what your written scheme and insurer require. Statutory examination under PSSR is one thing, routine maintenance is another, and well-run sites plan both instead of treating them as the same job.
A proper boiler service usually means stripping and preparing the boiler for inspection, cleaning smoke tubes, carrying out a water-side clean, sweeping the furnace, servicing associated boiler valves, and rebuilding once inspection work is accepted. We also look at the pieces around the boiler that affect reliability, not just the shell itself.
Yes. That is one of our core service lines. We strip and prepare, clean through, remove and refit valves as needed, replace sight glasses and manhole joints where required, and support the inspection process so your site is ready on the day.
The boiler needs to be safely isolated, opened up, cleaned thoroughly, and made accessible for examination. Any items called for in the written scheme or previous report need to be dealt with beforehand, because the slowest inspections are usually the ones where access, cleanliness or paperwork were left until the last minute.
Yes. We already position that as part of our boiler servicing offer because it makes the annual service far more straightforward for the client. It keeps the handover cleaner and helps avoid the usual confusion over what was prepared, what still needs attention and what is waiting on acceptance.
It is the work needed to expose the right areas of the boiler before non-destructive testing takes place. That can include removing lagging and cladding, taking out refractory in specific areas, preparing shell and weld surfaces, and then reinstating the boiler once the NDT work is complete.
Because the competent person or NDT scope needs access to the actual surfaces being examined. If the shell, weld areas or key inspection points are hidden behind cladding, lagging or refractory, you cannot carry out proper ultrasonic testing or other examination in a controlled way.
The next step depends on what has been found and what the competent person requires. We can support the practical side by carrying out the strip-down, access work, component replacement, repairs and reinstatement, but the examination findings and any formal compliance decisions still sit within the examination and reporting process.
Yes. That is part of our boiler overhaul and repairs offer. We can strip down, prepare, support the inspection stage and rebuild the boiler afterwards so the job moves from examination back to service without unnecessary delay.
Repeated leaks, poor combustion-related performance, recurring valve trouble, refractory breakdown, smoke-box deterioration, pressure-related defects and a growing list of annual remedials are all warning signs. If your shutdown list gets longer every year, you are usually into overhaul territory rather than light servicing.
Yes. We cover furnace repairs, smoke-box repairs, refractory repairs and associated rebuild work around the boiler. Those jobs matter because they affect safety, combustion conditions, access for inspection and the general health of the plant.
Yes, and that is often the right time to do it. We service and test boiler valves including blowdown valves, TDS valves, feedwater valves, gauge cocks, level gauge valves and other trim so the shutdown deals with the whole boiler package rather than just the pressure vessel.
On site, people usually mean the operational checks carried out with the insurance inspector after the boiler has been prepared and reassembled. The exact scope depends on the plant and the examination requirements, but the point is simple: it proves the boiler and its protective arrangements in working conditions, not just in pieces on the floor.
Yes, steam at any pressure is a relevant fluid under PSSR. That is why steam boilers and their associated protective devices, vessels and dangerous pipework sit inside a formal safety framework rather than being treated as ordinary mechanical plant.
It is the document that sets out what parts of the pressure system must be examined, how often, and under what conditions. A suitable written scheme must be in place before qualifying pressure equipment is used, and the system must then be examined in line with that scheme.
No. A statutory examination carried out to the written scheme is not a substitute for regular maintenance. A boiler can be technically due for examination and still be poorly maintained, which is why planned servicing matters.
For an installed steam boiler, the user of the system carries the duty under PSSR. The competent person examines or certifies the scheme, but the site still has to operate, maintain and prepare the system properly.
Yes. Preparing the boiler and carrying out the mechanical work is different from acting as the competent person. We handle the strip, clean, access, valve work, rebuild and practical engineering, while the competent person carries out the examination and reporting role independently.
We work to the inspection scope, plan access properly and deal with the usual problem areas before they hold up the programme. The real gain comes when boiler work, valve work, pipework remedials and inspection preparation are lined up as one shutdown package instead of four separate jobs.
Yes. A boiler that sits idle can still have corrosion, stuck valves, dirty water spaces, degraded gaskets and stale remedials waiting for the next demand peak. Occasional use is not the same as no risk.
Yes. We cover feedwater pipe repairs, blowdown pipework, TDS lines, blowdown tank connections and other boiler ancillary pipework. Those lines are easy to ignore until they start leaking or fail an inspection, but they are part of the boiler story.
In simple terms, dissolved solids and impurities stay behind when steam is formed. If they are not controlled properly, they concentrate in the boiler water and can create deposits, carryover and operating problems.
Dirty tubes restrict heat transfer and make the boiler work harder than it should. That is why rodding smoke tubes and cleaning through are built into routine servicing rather than treated as optional extras.
Yes. We support burner-related works around the boiler, including burner hoses, fault-finding support, refractory around the burner and related housing or ancillary repairs. We focus on the mechanical work around the combustion package so the boiler side is not left half-finished.
Yes. Our service range covers boiler auxiliaries, feed systems and associated pipework because the boiler only runs properly when the supporting equipment is in order. A clean shell with neglected feed systems still gives you trouble.
Yes. We provide hire boiler connections, temporary steam and water connections, changeover work and recommissioning support. That is often the fastest route to keeping a site running while the main boiler is repaired or overhauled.
Usually it means controlled isolation, safe disconnection of the temporary set-up, reinstatement of the permanent lines, checks on valves and drains, and a careful recommission of the main boiler. It needs planning, because a rushed changeover can leave you with leaks, wet steam or protection issues that only show up once production starts.
Yes. We cover boiler decommissioning, isolation, blanking and capping of services, and removal preparation. The aim is to leave the plant properly made safe and clearly set out, not half-disconnected and waiting to surprise somebody later.
Keep your examination records, service reports, defect actions, calibration paperwork where relevant, and any test or traceability certificates tied to repaired or overhauled items. Good records matter because insurers, auditors and your own maintenance team all need a clean history when the next shutdown comes round.
Earlier than most sites do. Once inspection dates, production planning, access work, valve overhauls and parts lead times start colliding, the shortcut is always to book late and pay for it in pressure. The better approach is to lock the shutdown in while there is still time to plan around it.
Yes, if the condition is being managed properly and the recurring weak points are tackled on purpose. Older boilers often respond well to disciplined servicing, valve work, pipework remedials and sensible overhaul decisions, but they do not improve when every problem is pushed to the next shutdown.
Not automatically. Lowering boiler pressure can create control, safety valve and steam-quality issues if the wider system is not set up for it, so we look at condensate return, insulation, traps, losses and controls before telling a client to chase pressure reduction.
Your team should know the safe operating limits of the pressure system and be able to show that the plant is being run within them. Boiler compliance cannot be separated from day-to-day operation.
Yes. We are used to work that needs to fit around production, hygiene, occupancy or critical-service constraints. The earlier we can see the shutdown window and scope, the easier it is to plan the work cleanly.
Yes. Planned boiler servicing, retained support and service agreements are part of our service structure because reactive-only maintenance is expensive and stressful. A good contract keeps standards up through the year rather than relying on one annual scramble.
Pipework, valves, steam, condensate and pumps
Yes. We handle steam line installation, replacement, alterations and fabricated sections, so if a line is past sensible repair we can replace it properly instead of dressing up a failing pipe. That matters on steam systems, where temporary thinking has a habit of becoming permanent risk.
Poor alignment, failing gaskets, thermal movement, corrosion, damaged flange faces and repeated heat cycles are the usual suspects. If a flange has leaked more than once, we look beyond the gasket and check how the line is supported and how the joint is being loaded.
First we make the line safe, isolate it and assess whether a temporary repair is even appropriate. After that, the right fix is usually section replacement, not wishful thinking, especially on steam, condensate or high-temperature services.
Yes. Condensate return leaks in roof voids and high-level routes are part of breakdown work on live sites, and they need careful access planning as much as welding or fitting. We treat those jobs as system problems, not just awkward leaks.
Yes. We fabricate spool pieces, elbows, tees, branch pieces and bespoke pipe sections to suit existing installations. That is often the cleanest way to carry out an alteration on older plant where standard off-the-shelf geometry will not line up.
Our service and parts range covers carbon steel, stainless steel and the usual industrial pipe, tube, fittings and flange arrangements used around boiler houses and steam systems. The right material comes back to the medium, temperature, pressure, connection standard and what is already installed on site.
Waterhammer is the impact caused when slugs of condensate hit fittings, valves or equipment at speed. It is not just noise. In severe cases it can fracture pipeline equipment and release live steam, which is why banging pipework should never be written off as one of those things.
Good drainage, correct pipe falls, sound supports, sensible valve operation at start-up and properly working traps all matter. Condensate control and regular maintenance are key parts of prevention.
It gets condensate out of the line before that condensate damages heat transfer, creates wet steam or causes waterhammer. Drainage is one of the small details that decides whether a steam main feels stable or troublesome.
Because taking steam the wrong way can pull condensate and debris into the branch. Branch connections taken from the top of the main carry the driest steam, while side or bottom take-offs are more likely to bring wet, dirty steam to the equipment.
Stall happens when the steam pressure at the coil falls so low that the trap no longer has enough differential pressure to discharge condensate. That is a differential-pressure problem, not simply a bad trap, and it can lead to poor control, corrosion and waterhammer risk.
The usual clues are poor heat transfer, condensate backing up, visible live steam loss, noisy discharge, waterhammer or performance drift in the plant the trap is supposed to protect. The reason we survey traps rather than guess is that steam loss and trap failure are often bigger than the site thinks.
Because steam traps affect safety, heat transfer, energy use, condensate return and overall plant reliability. Good trap management removes condensate properly, reduces the chance of hazardous failures and helps stop live steam loss from quietly inflating fuel spend.
A sound survey identifies the trap population, checks whether each trap is the right type and correctly installed, tests the traps in operation and then reports the findings clearly. The result should be a practical remedial list, not a spreadsheet nobody uses.
Yes. Steam trap replacement, trap sets, trap stations, repair, supply and installation all sit within our steam and condensate offer and wider parts range. If a survey shows a trap is wrong, failed or beyond sensible repair, we can deal with the replacement side as well.
Yes. Returned condensate carries usable heat and treated water back to the feedtank, which cuts the need for fresh make-up water, chemicals and additional fuel. It is one of the most practical efficiency gains available on many steam systems.
Yes, they can if feedwater temperature climbs too far and NPSH conditions are poor. Very high condensate return rates can contribute to cavitation in the feedpump if the suction side is not designed properly.
We see trouble from poor NPSH conditions, hot condensate behaviour, worn seals and bearings, blocked or undersized return arrangements, fatigue from repeated cycling and faults elsewhere in the condensate system. The pump is often the victim of a system issue, not the root cause on its own.
Cavitation happens when water flashes locally to vapour at the pump eye and those bubbles then collapse violently as pressure recovers. The warning signs are usually noise, damage and unstable pumping, and the cure is tied to suction conditions, feedtank level and pipe sizing rather than guesswork.
Yes. Feed pumps, condensate pumps, multistage pumps and related overhaul work are all part of our pump services. We strip, inspect, rebuild and test rather than treating pump work as a swap-only exercise.
That depends on the condition of the casing, shaft, bearings, seals, motor and the duty it is being asked to perform. We look at repairability and what the pump is sitting inside, because replacing a pump without fixing the system fault behind it is a quick way to buy the same problem twice.
We work across safety valves, control valves, PRVs, relief valves, globe valves, ball valves, butterfly valves, check valves, gate valves and the boiler-house valve set around blowdown, TDS, feedwater and gauge duties. That breadth matters on older sites, where a shutdown often throws up a mixed bag rather than one neat valve family.
Yes. Safety valve service, calibration, testing and certification are core services for us, both in-house and on site. We can test using nitrogen, gas, water and air and provide traceable identification through our WE ID system.
Our stated range covers valves from 1/4 inch to 12 inch and test pressures up to 60 bar. For an unusual valve or difficult application, send us the make, size, set pressure and service medium before the shutdown so we can confirm the route.
It is the Warden Engineering traceability number used to tie the valve back to its overhaul and test history. That matters on plants with multiple similar valves because it stops paperwork becoming vague the moment the valve leaves the bench.
Yes. Our service range covers control valve overhaul and repair, actuator work, positioners, recalibration and assembly testing. That is useful when the symptom on site looks like a process issue but the real cause is a worn trim, drifting actuator or damaged seat.
Yes. We service PRVs and the wider station, including the valves, gauges, strainers and associated pipework around them. A PRV station is only reliable when the whole arrangement is looked at together.
Because if the pressure reducing valve fails, downstream pressure can rise above the allowable working pressure of the equipment being protected. The downstream safety valve is there to vent excess pressure and prevent damage and danger to personnel.
Yes. Those valve types sit directly inside our boiler valve servicing and wider valve services. They are exactly the sort of components that cause grief during shutdowns because they are critical, awkwardly located and often left until they become urgent.
Yes. We offer valve collection, workshop overhaul and return as a specific service. For sites trying to shorten shutdowns, that can be the difference between planned turnaround and valve work taking over the week.
Where required, we can support overhaul and test certification, traceability through WE ID numbers, and documentation tied to the work carried out. ISO 9001:2015-backed overhaul and test certificates form a core part of how critical valve work is controlled.
Yes, provided the requirement is clear at quote stage. We can support supply routes tied to standards and approvals including EN ISO 4126-1, EN 12266-1, EN 837-1, EN 10204 3.1, EN 1092, WRAS, ATEX, API 607 and ISO 10497 where relevant to the product and application.
Yes. We can source pressure gauges with UKAS calibration certificates or calibration traceable to UKAS, along with gauges manufactured to EN 837-1 and specified for the application where required.
Yes. Our parts and components range includes sight glasses, gauge glasses, armoured and reflex glasses, gauge cocks, level gauges and related spare parts. Those items look small on paper but they are central to safe, readable boiler operation.
Yes. We supply flange gaskets, inspection plate gaskets, manhole joints, mud door gaskets, graphite jointing, ladder tape, packing and service kits. For shutdowns, the best approach is always to identify those seals early rather than after the boiler is already open.
Yes. Our product range goes well beyond valves. It includes traps, pumps, fittings, flanges, gaskets, gauges, burner parts, fabricated items, jackets and insulation accessories, which means the site does not have to split engineering and supply into separate conversations.
Often, yes. We work across a wide range of valve types and historic supplier brands, so if you send us photos, sizes, markings, pressures, temperatures and any old paperwork, we can usually narrow it down far faster than a cold search from a blank page.
Yes. Proper insulation reduces heat loss across the steam distribution network, and that includes the valves and fittings people often leave bare. Valve jackets and insulated coverings are a practical efficiency measure, not a cosmetic extra.
Because they protect the station and improve steam quality. The separator removes entrained water upstream, while the strainer keeps debris out of the valve and helps the assembly work as it should.
Yes. Many jobs sit in the middle ground between patch repair and full replacement. We handle pipework alterations, welded and flanged modifications, remedial steam-line work, fabricated sections and plant changes where the aim is to improve a live system without rebuilding the whole site.
Breakdowns, testing, fabrication, decommissioning and support
Yes. Emergency industrial repairs and steam leak response are part of our breakdown service, including steam valves, flanges, joints and line repairs. On a live site, the first priority is always to make the area safe and control the risk before anything else starts.
Treat it as a safety issue, not a nuisance fault. Keep people clear, isolate if that can be done safely under your site procedures, and do not send somebody into a hot, low-visibility area just to have a quick look while the line is still live.
Yes. Out-of-hours engineering support and UK-wide breakdown response are built into our service structure, which is exactly what many factories need when a line fails outside the normal maintenance window.
Yes. Our reactive service covers industrial hot water leaks, cold water leaks, condensate leaks and pipework failures as well as steam. Most plant rooms are mixed-service environments, so the support needs to reflect that.
A temporary repair gets a site through the immediate risk and production pressure. A permanent repair restores proper integrity, support, alignment and materials so the same point does not fail again at the next heat cycle or start-up. The two should never be confused.
Yes. On-site pressure testing, plant room testing, valve testing and certification support are all part of our offer. That can be especially useful when equipment is too large, too fixed or too site-specific to send elsewhere.
In practical terms, it is a controlled pressure test using liquid to prove the integrity of a line, vessel or component. Pressure testing is a serious activity in its own right, and hydraulic testing is generally safer than pneumatic testing because the stored energy risk is lower if something goes wrong.
Usually after certain repairs, modifications, overhauls or new installations, and wherever the specification, code, client requirement or examination process calls for it. The exact trigger depends on the item and the risk, which is why we prefer to tie testing into the planned scope instead of deciding it on the shop floor.
Yes. Pressure gauge testing, calibration, certification, proving and replacement are part of our service range, with UKAS and UKAS-traceable calibration routes available where required.
It usually means helping the site with the practical work around the pressure system so examination, pressure proving, access, isolation and reporting can happen to plan. We support the maintenance and site-testing side, while the independent competent person handles the formal examination and written scheme role.
We do not treat live, pressurised steam systems as welding jobs. The line has to be properly isolated, drained, made safe and prepared before hot work starts, and that preparation is part of doing the work responsibly.
Yes. Our welding and fabrication services include industrial welding, site welding, workshop welding, coded welding support, pipe welding and steel fabrication. That lets us carry the job from fault or scope through to the fabricated fix, rather than leaving the site to coordinate several trades.
Yes. We fabricate support brackets, pipe supports, manifolds, steelwork, custom fabrications and plant support steelwork. That matters because unsupported or badly supported pipework is often behind repeat leaks and long-term misalignment.
Yes. Plant alterations, changeovers, steam-line modifications, remedial works and decommissioning all sit inside our service structure. Shutdown periods are usually the right time to combine those works with inspection preparation and overdue remedials so the site only pays the access and outage penalty once.
That normally means safe isolation, confirming the line is no longer in service, draining down if required, blanking or capping the route, and leaving the remaining system clear and secure. Good decommissioning removes confusion as much as pipework, which helps immensely on busy sites a year later.
Yes. Blanking off and capping steam, condensate and other plant services is specifically included in our decommissioning work. It is a small detail with big consequences, because abandoned live links create risk and dead legs create headaches.
Before it chooses the date for you. If corrosion, repeated leaks, support failure, awkward temporary fixes and shutdown remedials are all growing at once, a planned outage replacement is usually cheaper and calmer than waiting for a weekend failure in production.
Yes. We support clients across the country and work across a broad mix of locations and sectors rather than one local niche. That suits groups with several plants who want a consistent engineering contact.
We support food factories, hospitals, pharmaceutical facilities, laundries, packaging plants, breweries, animal-feed sites and utility-related operations. These environments rely on dependable steam, hot water, condensate or pressure-system performance.
Yes. These are the kind of sites where inspection readiness, traceability, calibration and shutdown planning really matter. The engineering answer is never just stop the leak. It is stop the leak, keep the paperwork straight and get the plant back in service cleanly.
Give us the service medium, pressure, temperature, size, location, access constraints, shutdown dates, photos, and any previous reports or valve lists. The clearer the starting information, the faster we can decide whether the job needs parts supply, workshop overhaul, on-site attendance or a fuller shutdown plan.
Yes. Those are often the fastest way to make sense of ageing plant, especially where nameplates are poor, asset registers are patchy or the site needs a decision before the next service window. Even a few decent photos can save a lot of wasted site time.
Because reactive-only maintenance waits for risk, disruption and poor timing. Planned servicing and regular survey work protect uptime, keep standards up, and stop small faults turning into emergency outages or failed inspections.
Yes. Boiler servicing, valve work, pump support, pipework repairs and planned maintenance all sit under one engineering offer, which makes life easier for sites that want a joined-up maintenance plan rather than a stack of separate subcontractors.
Because the cheapest day to solve a steam problem is usually before it becomes urgent. Early input lets us line up the right service scope, certificates, access, shutdown timing and parts instead of trying to rescue a plant that is already leaking, waiting for inspection or running with known defects.
