Steel Pipe
About Product
VI with its extraordinary vision into future has started ERW stainless steel pipes production in 2008. Equipped with latest facilities, We are committed to produce quality product in various sizes.
The Process commences with the formation of welded mother tube on the tube mill from prime quality stainless steel strips. The latest TIG multi electrode welding technique is employed for superior weld quality and 100% Fusion with argon purging, No filler metal added
These mother tubes are solution annealed at 1060 D 1100 D. C in continuous annealing furnace followed by immediate quenching to prevent chromium carbide precipitation
Annealing of mother tuber ensures:
- Removal of stress induced during tube forming and cold drawing
- Sufficient ductility and softness for cold drawing
- Transformation of the weld zone to austenitic nature
- Re crystallization of metallic grains to original form and thereby improving corrosion resistance
Testing and Quality Control
Corrosion Test
Conducted only on special request by customer.
Flange Test
Confirm the cracks on the welded sections or on the base metal.
Eddy Current Test ASTME-426
This test is conducted to check the homogenates throughout the pipe length.
Radiographic Test
On demand, through approved inspection agency we can provide this test.
Bending Test
Conducted to check the leakage at different preserver by Hydrostatic and pneumatic pressure test.
Flange Test
This test is conducted to check the strength of welded section. Welded section should bear this specified compression stress.
Reverse Flattening Test
To confirm that there are no cracks or blow holes on the welded section.
Flaring Test
(Flaring) test is performed to ensure the forming behavior of pipes. Pipe ends are expanded in a press to a diameter 1.2 times the outer diameter of pipe.
