Heat-exchanger tube fabrication – U-bending, tube bundles, passivation

In short: for heat exchangers we supply U-bent alloyed boiler tubes (e.g. 16Mo3, 13CrMo4-5), welded into the tube sheet with qualified procedures. For stainless tubes we also provide passivation.

Re-tubing a heat exchanger is a typical shutdown job where time is the most expensive factor. Tubes should be sourced pre-bent and inspected to the bundle's dimensions, so that only installation remains during the shutdown.

What we do:

  • sourcing tubes in the specified grade and standard (e.g. EN 10216-2, ASTM A213);
  • U-bending to the bundle geometry;
  • welding into the tube sheet with qualified procedures;
  • passivation of stainless tubes.

What we need for a quote: bundle drawing or tube list (OD × wall, lengths, bend radii), grade, certificate requirements and deadline.

Frequently asked questions

Who is this service for?

Heat-exchanger manufacturers and repairers, and plant operators re-tubing a bundle during a shutdown. We deliver the tubes pre-bent and inspected to the bundle's dimensions.

Which heat-exchanger tube materials can I order?

Alloyed boiler tubes (e.g. 16Mo3, 13CrMo4-5) and stainless tubes, to the specified standard (e.g. EN 10216-2, ASTM A213).

Do you supply only the tubes, or install them too?

Either: we deliver the tubes bent, and on request we also weld them into the tube sheet with qualified procedures.
