-Customer Specifications.

Duplex Stainless Steel U Bend Tube , ASTM A789 S31803 (SAF2205), ASTM A789 S32750 (SAF2507), S32760

Bending Radius: From 1.5*OD(Outside Diameter) To 1500mm

When Ordering Tubes With Radius less or equal to 1.5*OD, It Is Necessary To Agree Precision Of Geometrics.

Straight Tubes Maximum Length:(Before Bending): 35000 mm.

Leg Length: Min 1 Meter, Max. 16500 mm (For Max R=1500mm)

Note: Other Size Are Available Upon Agreement.

Heat Treatment: Stress Relieved After U-Bending (Bending Area Plus 300MM For Each Leg).

Hydrostatic Test After U Bending: Maximum Test Pressure 600 Bar, Soaking 10 Sec. With 

Dematerialized Water. Compressed Air Cleaning After Hydro-Test.

Packaging: In Strong Transport-Worthy Pre-fumigated wooden boxes of corresponding dimensions for 

each tube Length, Radius, Diameter, According To PO requirements as well as wrapped In polyethylene 

films With soft plastic caps on both end of Tube.

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:

  • Eddy Current Testing
  • O.P Testing
  • Radiography Testing
  • Corrosion Testing
  • Micro Testing
  • Macro Testing
  • IGC Testing
