Product Description
ASTM A312 TP316L Stainless Steel Seamless Pipe
ASTM A312 TP316L is a low carbon austenitic stainless steel grade manufactured through cold rolling processes. This premium material features high-quality nickel, chromium, and molybdenum composition, delivering exceptional corrosion and oxidation resistance for demanding industrial applications.
Product Specifications
This grade covers standard seamless, welded, ERW, EFW, and cold drawn pipe assemblies designed for high-temperature and high-pressure applications in the petrochemical industry. The seamless manufacturing process involves hot billets being passed through extruded metal to achieve precise dimensional accuracy.
Key Features
- Excellent corrosion and oxidation resistance
- Superior load carrying capacity and strength
- No welds or seams on pipe surfaces
- Enhanced surface finish from cold drawing process
- Suitable for high-temperature and high-pressure applications
Manufacturing Processes
Seamless Pipes: Produced by passing hot billets through extruded metal for precise sizing.
ERW Pipes: Manufactured by rolling sheet or strip and forming longitudinal seams using high-voltage current welding.
EFW Pipes: Produced with high-speed beams converting kinetic energy into heat for welding.
ERW Pipes: Manufactured by rolling sheet or strip and forming longitudinal seams using high-voltage current welding.
EFW Pipes: Produced with high-speed beams converting kinetic energy into heat for welding.
