Swaging Boiler Tube – Swaged Tube

With our Tube end forming and swaging, Aditya Steel Engg co. can presently conduct boiler tube swaging fittings in-house. With the use of one of our several inverse draw mandrels, these swagers can regulate and maintain the final wall thickness.

Tube end forming and swaging is a manufacturing method that involves forcing a tube or pipe end through a die or set of dies using hydraulics to enlarge or reduce the OD (Outside Diameter) of the tubing or pipe. This is a “cold” process that does not involve heat. This procedure compacts the material, producing work hardening and necessitating a heat treatment / annealing step to match the material standards. The swaging technique will also increase the wall thickness, reducing the ID (internal diameter) of the tube/pipe.

Heat Treatment Proceedure

When tube swaged ends require heat treatment to satisfy ASME / Customer requirements the swaged area and the transition of the swage will be given appropriate heat treatment using an induction heating furnace with temperatures as follows:

  • P1  1,600° F – 2,100° F ( .750″ Max wall thickness)
  • P-3 1,600° F – 2,100° F ( .50″ Max wall thickness)
  • P-4 1,600° F – 2,100° F ( .50″ Max wall thickness)
  • P-5A 1,600° F – 2,100° F ( .50″ Max wall thickness)
  • P-5B 1,650° F – 1,950° F ( .50″ Max wall thickness)
  • P-8 1,400° F – 2,100° F
