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:
