About Heat exchanger repairing

We provide reliable tube changing services for various machines and equipment. Our technicians carefully remove the damaged or worn-out tube and replace it with a new, high-quality tube to ensure proper performance, safety, and durability. The service is carried out using the appropriate tools and techniques, minimizing downtime and ensuring smooth operation.

Comprehensive Heat Exchanger Repair Services

Our heat exchanger repair solutions are tailored to accommodate a range of repair types, from tube replacements to leak fixing and descaling. Whether your job requires maintenance, overhauling, or full refurbishment, our skilled technicians restore units to optimal functionality and compliance with design specifications.

Quality Assurance Through Rigorous Inspection

We utilize advanced inspection techniques-hydro tests, dye penetrant, eddy current, and visual examination-to ensure repairs meet stringent industry standards. Each repaired exchanger undergoes a thorough check at up to 1.5 times its design pressure, ensuring safe and reliable operation post-service.

Durability Enhanced by Protective Coatings

To maximize equipment lifespan, we apply anti-corrosive coatings and linings after completing the main repair. Surfaces receive grit blasting and professional finishing, guarding your heat exchanger against harsh process environments and minimizing downtime for future maintenance.

FAQ's of Heat exchanger repairing:

Q: How is the repair process of a shell and tube heat exchanger conducted?

A: The repair process involves initial inspection using hydro, dye penetrant, and eddy current tests, followed by cleaning (water jetting, chemical, or mechanical), replacement or repair of damaged tubes, welding, leak fixing, then finishing with anti-corrosive coatings and surface painting.

Q: What materials can be repaired in your service?

A: We handle heat exchangers constructed from carbon steel, stainless steel, and a range of alloy steels, selecting the best suited process and materials based on application and operating environment.

Q: When is it necessary to refurbish or repair a heat exchanger?

A: Refurbishment is required due to performance loss, leaks, corrosion, fouling, or mechanical damage-typically detected during routine maintenance, inspection, or upon noticing reduced process efficiency.

Q: Where are repair services provided?

A: Our team offers both onsite repair at client facilities and offsite repair at our workshop, depending on the size, complexity, and urgency of the refurbishment required.

Q: What are the main benefits of professional heat exchanger repair?

A: Repairing and refurbishing your heat exchanger restores thermal efficiency, ensures compliance with safety standards, extends equipment lifespan, and reduces the cost and downtime associated with full replacement.

Q: What is the typical turnaround time for repairs?

A: We generally complete heat exchanger repairs within 1 to 3 weeks, with the exact duration determined by the unit's size, condition, and extent of damage.

Q: How do you ensure the repaired unit is safe for operation?

A: Post-repair, we conduct rigorous inspection and pressure testing-most notably a hydro test at 1.5 times design pressure-to verify the exchanger's structural integrity and operational readiness before returning it to service.
