    Customer Specifications.


    Bending Radius: From 1.5*OD(Outside Diameter) To 1500mm

    When Ordering Tubes With Radius less or equal to 1.5*OD, It Is Necessary To Agree Precision Of Geometrics.

    Straight Tubes Maximum Length:(Before Bending): 35000 mm.

    Leg Length: Min 1 Meter, Max. 16500 mm (For Max R=1500mm)

    Note: Other Size Are Available Upon Agreement.

    Heat Treatment: Stress Relieved After U-Bending (Bending Area Plus 300MM For Each Leg).

    Hydrostatic Test After U Bending: Maximum Test Pressure 600 Bar, Soaking 10 Sec. With

    Dematerialized Water. Compressed Air Cleaning After Hydro-Test.

    Packaging: In Strong Transport-Worthy Pre-fumigated wooden boxes of corresponding dimensions for

    each tube Length, Radius, Diameter, According To PO requirements as well as wrapped In polyethylene

    films With soft plastic caps on both end of Tube.


    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.

    Supplementary Testing : Apart from the above mentioned tests, we also carry out on the manufactured products supplementary testing. The tests conducted under this include:

    • Eddy Current Testing
    • O.P Testing
    • Radiography Testing
    • Corrosion Testing
    • Micro Testing
    • Macro Testing
    • IGC Testing
    • Ultrasonic testing
    • Liquid Penetrate testing
