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.
