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:
