  • Test & Qualification Facilities

    Our manufacturing units are equipped with testing and qualification facilities for various functional and prototype tests.

  • Non-Destructive Test

    NDT is carried out by ASNT level II qualified personnel :
    Non-destructive testing methods are used to examine a valve.
    They identify the cracks in the body, discontinuities in the material include porosity, wall thinning from corrosion and other sorts of disbands.
    Radiographic tests are used for volumetric casting defects
    Ultrasonic tests are used for forging defects
    Magnetic particle test and liquid penetration tests are used for surface defects

  • Surface test

    Used to detect blow, scar, and blister on surface of casting -Magnetic particle test and liquid penetration test are used for surface casting defects.

  • Fugitive Emission Test

    Fugitive emission tests to evaluate the amount of fugitive emission leakage through the stem gland packing and shell joints.
