Duplex Steel Seamless Tube  Quality Test:
 

Corrosion TestConducted only when specially requested by the client
Chemical AnalysisTest done as per required quality standards
Destructive / Mechanical TestingTensile | Hardness | Flattening | Flare | Flange
Reverse-bend and Re. flat testsCarried 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 TestingDone to detect homogeneities in subsurface by using Digital Flaw-mark Testing System
Hydrostatic Testing100% 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 TestTo check any evidence of air leakage
Visual InspectionAfter passivation, every single length of tubes & pipes is subjected to thorough visual inspection by trained staff for detecting surface flaws & other imperfections
