Manufacturing Process of Stainless Steel "U" Tubes

In addition to the production of Straight Stainless Steel Tubes, Petroinox also manufactures ‘U’ Tubes for use in heat exchanger, condensers, pre-heaters & various other equipment.

The manufacturing of ‘U’ Tubes takes place in a separate shop, which is adjacent to the tube mill. This is done by utilizing bending equipment that is used exclusively for stainless tube bending as per the drawings & specifications given by our customers. In the process bending portion, a six-inch leg is stress relieved by resistance heating. And to avoid oxidation in ID, argon gas is passed inside according to the required flow rate.
