Other Specialty Services
Internal Tube Support Replacement
We understand the critical role that tube supports play in the overall performance and longevity of your equipment. With meticulous precision, our highly skilled technicians ensure that each tube is expanded at the proper distance and to exact specifications. By doing so, we minimize leak risks that can be caused by vibration or misalignment.
Tube Sheet Replacement
The process of replacing an eroded tube sheet is an invasive process that includes cutting out the damaged tube sheet and expertise in welding on a new custom tube sheet. This requires aligning the new sheet with the tubes and process requires prepping the tubes, applying sealant, and carefully expanding the tubes for the right amount of elastic deformation.
Epoxy Coating
Epoxy coating offers several benefits for condenser tube sheets and heads. It provides excellent corrosion resistance, protecting against damage from corrosive substances and extending the lifespan of the condenser. It also helps prevent leaks and ensures the integrity of the tube sheet and head, minimizing downtime and potential damage. Epoxy coating can withstand high temperatures, making it suitable for demanding condenser applications.
