Heat Exchanger Cleaning
Heat exchanger cleaning is an essential maintenance process that ensures optimal heat transfer efficiency, extended equipment life, and safe plant operation. Over time, heat exchangers accumulate fouling, scaling, sludge, and corrosion deposits that reduce performance and increase operational costs.
Metalok Industries provides comprehensive heat exchanger cleaning services, including mechanical, chemical, and high-pressure water jet cleaning, tailored to the exchanger type and fouling condition. Our certified technicians follow precise cleaning methods to remove all contaminants without damaging the tubes, tube sheet, or shell structure.
Using advanced tools and environmentally safe cleaning agents, Metalok ensures maximum cleaning efficiency, minimal downtime, and compliance with ASME and API maintenance standards. Post-cleaning, every exchanger undergoes inspection and leak testing to confirm readiness for operation under design conditions.
- Inspection and Preparation: The fin fan heat exchanger is inspected to identify the extent of the damage or corrosion in the tubes. The exchanger is then cleaned and prepped for the retubing process.
- Tube Removal: The old tubes are removed using specialized equipment, such as tube cutters or pullers. Care must be taken to avoid damaging the fins or any other components during the removal process.
- Fin Inspection and Repair: The fins on the heat exchanger are inspected for damage or corrosion. Any damaged or corroded fins are repaired or replaced as necessary.
- New Tube Installation: The new tubes are then installed in the heat exchanger, typically using a tube expander to ensure a secure fit between the tubes and the fins.
- Final Inspection: The heat exchanger is then inspected again to ensure that the new tubes are properly installed and free of any damage or defects. The exchanger is then reassembled and tested before being put back into service
