Test Items:
|
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 |
