2. Onsite Cleaning Xchanger has developed superior methods and procedures for cleaning heat exchangers and condensers to achieve maximum efficiency. Xchanger inspects each unit so that blockages and improperly plugged tubes can be detected, marked and repaired. Regular maintenance of heat exchangers and condensers should include cleanings to keep equipment operating most efficiently. Key Benefits of Tube Cleaning Heat Exchangers and Condensers More efficient steam cycle Lowered heat rate Xchanger can clean your heat exchanger or condenser tubes using many different methods. The method will depend primarily on the nature of the deposits. Typical downtime for heat exchanger cleaning is less than a week, but most jobs can be cleaned and returned in one to two days if required. We maintain a large inventory of cleaning equipment and can respond quickly.

10. Welding Services Xchanger has considerable experience and expertise to complete welding and fabrication assignments. We maintain quality programs to insure that any project is completed in a professional manner. Welding and fabrication projects can be completed at your site or in our warehouse in Cartersville GA. Due to our attention to quality, we are holders of the “R” stamp as issued by the National Board of Columbus Ohio. This allows us to make repairs to vessels manufactured and registered to the American Society of Mechanical Engineers (ASME) Section VIII code. We are also able to fabricate or repair piping systems meeting specifications of B31.1.

13. Chemical Cleaning Xchanger can immerse your heat exchanger in a cleaning solution. This process will remove baked on residue from both the outside and inside of the tubes or plates. This allows all tubes to be cleaned. This chemical bath will not harm copper, stainless steel or carbon steel tubes. In addition to cleaning heat exchangers by immersion, we will pressure or vacuum test each tube to discover leaks.

14. Heat Exchanger and Condenser Retubing Key Benefits: Extensive experience using superior tooling, people and procedures Proper documentation of retubing process Reduced outage time Xchanger has extensive experience in the retubing field. Using superior tooling, qualified personnel and proper written procedures, we ensures that your retubing project is performed correctly. This assures you that the heat exchanger or condenser is returned to its original condition ready for years of service. During our retubing process we insure you will not have any units that fail prematurely due to improper installation. Xchanger will document the entire retubing process, including documentation to where each lot of tubes is located. This is important if the metallurgy of one heat of raw material leads to premature tube failure. Xchanger uses state of the art removal tools. Should your unit need to be retubed in a short period of time, we can accomplish this task using these state of the art too ls.
