    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.
