Before you replace costly equipment, talk to an American professional about our proven, cost-effective retubing and rebuilding services. American repairs can extend the life of existing equipment 20 to 30 years, helping you avoid a major capital expense. We are fully equipped to rebuild heat exchangers regardless of size-----either at our ASME code shop or on-site.
Full engineering support.
Our thermal and mechanical engineers can provide options for alternate rebuilding materials or to redesign your heat exchanger to meet new performance criteria. We can also analyze and correct any problems or redesign defects which caused the heater or condenser to fail.
Quick and cost-efficient.
On-site retubing can be done in just 1 to 6 weeks. Our computerized project planning and scheduling keeps you constantly apprised of project progress. We can permanently repair most feedwater heaters and condensers for 25%-50% of the cost of installing a new replacement.
Proven procedures and methods guarantee results.
Following a thorough examination of your equipment, our engineers will provide a comprehensive report of the reasons for tube failure and recommendations for corrective action. With the channel open and the shell removed, damaged tubes are cut and removed from the bundle. Tube supports, zone shroudes, tie rods and spacers are inspected, cleaned and replaced if necessary. Tube stubs are removed from the tube sheet and tube holes are cleaned, inspected and prepared for new tube installation.
The new tubes are carefully installed, with great care taken to prevent scratching, scoring, denting and bending. Tubes are positioned in the tubesheet and then mechanically or explosively expanded.
The shell is reinstalled and an air test is performed to check for tube joint leaks, with re-expansion performed as needed. Then the channel is closed and the unit is hydrotested. A code stamp is applied as required to the vessel and it is returned to service.
