For high-temperature service such as for superheaters and reheaters



Boiler, Superheater, Heat Exchanger, Condensor Tubes

Austenitic stainless steel, temperature service applications, high temperature applications



The tubes are made from flat-rolled steel by an automatic welding process with no addition of filler metal.

Subsequent to welding and prior to final heat treatment, the tubes are cold worked on weld and base metal or in weld metal


Test and inspection:

Tension test

Flattening test

Flange test

Reverse-Bend test

Hardness test

Hydrostatic or Nondestructive Electric Test
