    Tube Of Other Alloys And Steel Grades Can Be Produced Upon Agreement.

     

     

    Technical Requirements:

     

    Straight Tubes Standard Specification For Bending:

    ASME SA 213; ASME SB 163; ASME A789, ASME SA268, ASME SA269, etc.

    Marking: Before Bending By Marking Machine All Over The Tube Length (Bent Section After Heat

    Treatment Without Marking)

    Note: Marking is also possible After Bending On The Straight Parts Of U-Bending Tube.

     

    U-Bend Tubes:

    -TEMA RCB 2.31 Standard Of The Tubular Exchanger Manufacturers Association (9th Edition).

    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.

    Some of the quality tests carried out by us includes:

    Corrosion Test Conducted only when specially requested by the client
    Chemical Analysis Test done as per required quality standards
    Destructive / Mechanical Testing Tensile | Hardness | Flattening | Flare | Flange
    Reverse-bend and Re. flat tests Carried out in full compliance with relevant standards & ASTM A-450 and A-530 norms, which ensures trouble-free expansion, welding & use at customers end
    Eddy Current Testing Done to detect homogeneities in subsurface by using Digital Flaw-mark Testing System
    Hydrostatic Testing 100% Hydrostatic Testing carried out according to ASTM-A 450 norms for checking tube leakage, and biggest pressure we can support 20Mpa/7s .
    Air Under Pressure Test To check any evidence of air leakage
    Visual Inspection After passivation, every single length of tubes & pipes is subjected to thorough visual inspection by trained staff for detecting surface flaws & other imperfections


    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
