    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
    • Corrosion Testing
    • Micro Testing
    • Macro Testing
    • IGC Testing
    • Ultrasonic testing
    • Liquid Penetrate testing

     

     

    Duplex Stainless Steel have a structure that contains both ferrite and austenite. Duplex alloys have higher strength and better stress corrosion cracking resistance than most austenitic alloys and greater toughness than ferritic alloys, especially at low temperatures. The corrosion resistance of duplex alloys depends primarily on their composition, especially the amount of chromium, molybdenum, and nitrogen they contain.

     

    Standard: ASTM/ASME A/SA789, A/SA790, A/SA928, DIN17456/17458, EN10216-5. After negotiation, we can supply pipe with customer's special requirement.
