Stainless Steel U Bend Tube ASME SA268, ASME SA213 TP304 / TP304L / TP304H / TP304N
Features :

• '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 in ID.
• The radius is checked for its OD and wall thinning with the recommended specification.
• The physical properties and micro-structure is checked at three different position.
• Visual inspection for waviness and cracks 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 ID cleanliness of the tube.
• Thereafter pickled, dried, marked and packed.
• All procedure is strictly followed as per TEMA "C" and ASTM A-688.
