U-bent tube sizes

Sizes tolerances of U bend tubes are to fullfil the requirements of: ASTM A556 / 556M and DIN 28179

Heat treatment of U bent tubes

Post bending heat treatment by electrical resistance (Joule effect) is applied. The temperature is monitored and controlled during the process. It is possible to perform the heat treatment in a nitrogen atmosphere.

U bent tubes can be tested as follows
All materials are hydro-tested as standard. Stress relieving is carried out in a gas-fired furnace or solution annealed using an induction heat process. We can offer a range of additional testing on request, including dye penetrant and PMI testing.

• Hydrostatic Test
