Spiro-Gills provides expert heat exchanger repair services for industrial applications across the UK and worldwide. With over 70 years of heat exchanger expertise and dedicated field service teams, we deliver on-site repairs for shell and tube, air-cooled, plate, and finned tube heat exchangers — wherever your equipment is located.

Industrial Heat Exchanger Repair Services

When your heat exchanger fails or shows signs of reduced performance, downtime costs escalate rapidly. Spiro-Gills understands the critical nature of thermal equipment in process industries. Our comprehensive heat exchanger repair services are designed to restore efficiency, extend equipment life, and minimise costly interruptions to your operations.

From routine maintenance and cleaning to emergency breakdown repairs and complete retubing, we provide the full spectrum of heat exchanger repair solutions. Every repair is carried out to ASME U standards and documented in accordance with our BS EN ISO 9001:2015 quality management system.

On-Site Heat Exchanger Repairs — We Come To You

Our field service teams support clients across the UK and internationally with fast, expert intervention on all types of heat exchangers. Whether planned maintenance or emergency breakdown, we bring the workshop to you.

UK-Wide Coverage

Based in Stafford, our mobile repair teams provide rapid response throughout the United Kingdom. We regularly service clients in oil and gas facilities, petrochemical plants, power stations, and manufacturing sites from Aberdeen to Southampton.

International Field Service

As part of the DMI Group, we extend our heat exchanger repair capabilities globally. Our engineers have undertaken on-site repairs and maintenance projects across Europe, the Middle East, and beyond, supporting multinational clients with consistent service standards wherever they operate.

Emergency Breakdown Response

Equipment failures don't follow schedules. Our emergency response team is available to mobilise quickly when critical heat exchangers fail. We carry essential spare parts and specialised tooling to minimise downtime and restore your processes as rapidly as possible.

Types Of Heat Exchanger Repairs We Undertake

Shell & Tube Heat Exchanger Repair

We repair all configurations of shell and tube heat exchangers, including fixed tube sheet, U-tube, and floating head designs. Our services include tube plugging, tube replacement, shell repairs, nozzle replacement, and gasket renewal. As the only UK manufacturer of finned tube, we can supply replacement tubes that match or exceed original specifications.

Air-Cooled Heat Exchanger Repair

Our repair services cover finned tube coils, fan assemblies, drives, and structural components of air-cooled heat exchangers. We clean, straighten, and repair damaged fins, replace failed tubes, and restore fan performance to design specifications.

Plate Heat Exchanger Servicing

We provide comprehensive servicing of gasketed plate heat exchangers, including plate cleaning, gasket replacement, frame maintenance, and pressure testing. Our team handles all major plate heat exchanger brands and configurations.

Finned Tube System Repair

Drawing on our unique position as the UK's only finned tube manufacturer, we offer unparalleled expertise in repairing finned tube heat exchangers. From retubing coil assemblies to repairing damaged fins and headers, we restore thermal performance to specification.

Condenser Repair

Steam condensers and process condensers require specialised repair techniques. We undertake tube replacement, tube sheet repairs, waterbox refurbishment, and integrity testing to extend condenser service life.

Charge Air Cooler Repair

For power generation and marine applications, we repair charge air coolers, including cleaning, tube replacement, and structural repairs to restore cooling efficiency and engine performance.

Our Heat Exchanger Repair Process

Initial Inspection & Assessment

Our engineers conduct comprehensive visual and dimensional inspection to identify damage, wear, and performance degradation. We assess repair viability and provide clear recommendations with cost estimates.

Pressure Testing & Diagnosis

Hydrostatic and pneumatic pressure testing identifies leaks, tube failures, and integrity issues. This diagnostic phase ensures we address all problems, not just the obvious symptoms.

Mechanical & Chemical Cleaning

Fouling and deposits significantly reduce heat transfer efficiency. We employ mechanical cleaning methods and appropriate chemical treatments to restore heat transfer surfaces without causing damage.

Welding & Structural Repairs

Our coded welders undertake repairs to shells, channels, tube sheets, and structural supports. All welding conforms to recognised standards and is subject to non-destructive testing where required.

Retubing & Recoring

When tubes are beyond repair, we undertake partial or complete retubing. Using our in-house finned tube manufacturing capability, we produce replacement tubes to exact specifications. For severely corroded tube sheets, recoring may be recommended.

Reassembly & Final Testing

Following repairs, units are reassembled with new gaskets and seals. Comprehensive pressure testing and performance verification ensure the repaired heat exchanger meets specification before return to service.

Industries We Serve

Oil & Gas

Offshore platforms, refineries, and gas processing facilities depend on reliable heat exchangers. We repair reboilers, gas coolers, glycol systems, and process heat exchangers in demanding upstream and downstream environments. Our Achilles UVDB certification demonstrates our suitability for oil and gas industry work.

Petrochemical & Chemical

Corrosive processes and high temperatures create challenging repair scenarios. We service condensers, process exchangers, and cooling systems in chemical plants, applying appropriate materials and techniques for aggressive environments.

Power Generation

From charge air coolers on diesel generators to cooling water systems for turbines, we support power generation clients with responsive repair services. Our work on turbine auxiliary equipment and lube oil coolers helps maintain generation capacity.

Marine & Shipping

Seawater coolers and marine oil coolers require corrosion-resistant repairs. We understand the constraints of marine operations and provide repair solutions that withstand harsh saltwater environments.

Food & Beverage

Hygienic standards are paramount in food processing. We provide hygienic cleaning and repair services for pasteurisation systems, glycol chillers, and process heat exchangers used in food production.

Waste & Environmental

Energy recovery units, digesters, and heat recovery exchangers in waste processing facilities benefit from our repair and refurbishment services, supporting sustainable operations.
