Competitive Advantage:
1) Supply Best Prices Based On Good Quality And Timely Delivery.
2) We Have Advanced NDT Equipments For The Tests Such As Eddy Current Test, Hydraulic Test And So On.And the Pipes Are 100% Inspected of Leakage Test.
3) Wooden Case Package Which Is Strong And Suitable For Sea Transport And Which Is Our Main Method To Protect The Tubes.Also We Will Depends On The Sizes Of The Tubes To Select More Ecomony Packing Method By Bundle.
Test System:
|
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 |
