Quality Control in our group :

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
