This High Pressure 316L Seamless Stainless Steel Pipe is manufactured for pressure vessel fabrication and high pressure process lines where mechanical integrity is critical. Because the pipe is produced by the seamless method, it has no longitudinal weld and therefore no weld-related defects or heat-affected zones, allowing it to carry higher design pressures than welded pipe of the same wall thickness.
The 316L grade adds molybdenum for improved corrosion resistance, so the pipe performs well in both high pressure and mildly corrosive service such as chemical reactors, autoclaves and hydraulic systems.
Every length is cold drawn to close dimensional tolerance, solution annealed, pickled and hydrostatically tested at a pressure agreed with the customer. Outside diameter ranges from 6 mm to 630 mm with wall thickness from 0.5 mm to 30 mm, giving engineers the freedom to select a size that meets the required design pressure with an economical safety margin. The pipe can be supplied plain end, bevelled for welding, or threaded for screwed connections.

A: The allowable working pressure depends on outside diameter, wall thickness and design temperature. Our engineers can help calculate a suitable size for your pressure vessel or line if you share the design conditions.
A: Yes. Every length is hydrostatically tested at a pressure agreed with the customer, and eddy current testing can also be performed for critical service.
A: We manufacture to ASTM A312 and ASME SA312 as standard. Other standards such as EN 10216 can be produced on request.
A: We provide mill test certificates to EN 10204 3.1 and can arrange third party inspection. Contact us with your specification to receive a competitive quotation.
