ASTM A312 TP316L Stainless Steel Pipe

ASME SA 312 316L Seamless Pipe and SS 316L ERW Pipe manufacturer in India

ASTM A312 Tp316l is a grade of tubular products. Oshwin Overseas is a large supplier of all kinds of ASTM A312 Tp316l Pipe Dimensions. We manufacture pipes of different schedules under different diameters. There are ASTM A312 Tp316l Equivalent products in the market as well. But our ASME A312 Tp316l products are unique in that they could be used at subzero temperatures as well. Our Stainless Steel Pipe A312 Tp316l ranges from small to medium sizes. We can also produce custom ASTM A312 Tp316l Seamless pipes as well.

These seamless pipes are highly resistance to chloride corrosion and therefore the 316l Stainless Steel Pipe resistant to pitting and crevice corrosion even under chloride rich environments. Our Stainless Steel Pipe 316l Seamless products can be used in boats, marine applications, sea water purification systems and in waste water management applications as well. There are different schedules of the pipes to accommodate different diameters and wall thicknesses. The Stainless Steel Pipe 316l Schedule 40 is a medium range pressure containment capacity whereas the Stainless Steel Pipe 316l Schedule 10s has comparatively smaller wall thickness. Our 316l Seamless Pipe Schedule 40 Pipe are one of the most used in the oil & gas industries. Our electric resistant welded SS 316l Erw Pipe is stronger and can last longer. The advantage of 316l Welded Pipe is that it is easy to weld with or without filler materials. We also supply Square Pipe 316l which could be used for extra strength in structural applications. Please contact us for further details.

Why grade 316L for your piping project in the Marine industry and temperature up to 850ºC?

Grade 316 is an austenitic stainless steel that can operate from 450 degrees Celsius to 850 degrees Celsius roughly. The range differs depending on the pressure of a system, the components flowing inside the pipe and the environment outside it. Marine environment is full of chloride ions and the wind and water are salty.

The salty conditions catalyze all forms of corrosions because they act as a medium for electron transfer for oxidation and reduction chemical reactions. The 316L has a lower carbon content than the 316 which means, there is less intergranular precipitation and local corrosion due to welding. Also, the material has molybdenum in addition to chromium and nickel which is specifically resistant to chloride ion stress corrosion.

These properties make the pipe resistant to crevice and pitting corrosion under chloride ion. Since the marine environments is full of chloride ions, the 316L material is resistant to chloride ion corrosion, has an operating temperature range up to roughly 850 degrees Celsius (1550F to be exact), the combination makes the pipes suitable for piping projects in the marine industry and temperature up to 850 degrees Celsius.
