Stainless Steel U Tubes

We use latest type of U ' bending machine is used for the precision cold bending of Stainless Steel U Tubes. Specifically prepared jigs and fixtures are used to ensure three dimensional accuracy for 'IT bend tubes. Bending is done for all kind of heat exchanger, condenser, economizer, boiler tubes in Stainless steel seamless as well as welded. Subsequent to 'IT bending tubes are hydro tested and stress relieved if asked for. Also mock-up pieces are prepared for determining thickness reduction on the bend portion. Dye Penetrant testing on bend portion is done to detect cracks, flaws or any type of defects. Special packing is provided to prevent any damage of Seamless Stainless Steel U Tubes during transit. We are counted among the major SS U Tubes Suppliers based in India.

Heat Treatment of Stainless Steel 'u' Tubes
'U' bent portion + 300mm on each leg length are heated at 10500 C temperatures by transformer. The temperature is measured by an Optical Pyrometer. Cooling is done immediately by blowing cold air to avoid carbide precipitation.
