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:
