Retubing Services

Conco's in-house, full-service re-tubing operation can solve any heat exchanger issue. Sometimes tube testing finds excess pitting, advanced wall loss, or leaks that prohibit re-installation. Our re-tubing team can quickly return any heat exchanger to service with a full re-tube, partial re-tube, or single tube replacement. We have a large inventory of smooth and finned tubing in a variety of metals, diameters, wall thickness, fin heights and spacing of integral, wound, or plate fins.

  • All types of materials
  • Full, partial or single re-tube
  • Large and varied inventory to meet any need

Conco’s Re-tubing Specialist has thirty plus years’ experience.  Our team can reverse engineer, re-manufacture, or build you a new heat exchanger bundle in a fraction of the delivery time required to order new factory units.  Material certifications are included and units are built to ASME specifications.
