About the product
STAINLESS STEEL SEAMLESS & WELDED ' U ' TUBE
‘U’ bending is done by cold working process.
‘U’ bending is done to the required radius as per customer drawings.
• The bend portion and six inch leg is stress relieved by resistance heating.
• Inert gas (Argon) is passed through it at the required flow rate to avoid oxidation.
• The radius is checked for its OD and wall thinning with the recommended specification.
• Visual inspection for waviness and cracks checks is done with Dye Penetrant Test.
• Each tube is then hydro tested at the recommended pressure to check for leakage.
• Cotton ball test is done to check the inside cleanliness of the tube.
• Thereafter pickled, dried, marked and packed.
• All procedure is strictly followed as per TEMA “R”, “C”, “B” and ASTM A688.
We also manufacture tubes upto 30 meter long.
