ASME SA312 Seamless Pipe and A312 Welded Pipes Supplier in India


ASTM A312 Pipe

ASTM A312 grade covers standard stainless steel pipe grade. The ASTM A312 Pipe has alloying elements like chromium, nickel, copper, molybdenum, etc, which gives them excellent tolerance and resistance to corrosive and oxidative media across stress-induced setups. The versatile grade covers seamless, a range of heavily cold worked welded austenitic stainless steel and straight weld pipe modules. The ASTM A312 Schedule 40 Pipe is intended for use in high temperatures and is commonly seen in moderate pressure systems. The sch 40 pipe is a common schedule this pipe is available in the industry. The ASME SA12 Pipe is a pressurized vessel pipe grade designed for elevated pressure and temperature setups. These modules have good strength and don’t easily bend or distort in any circumstances.

The ASTM A312 Seamless Pipes within this grade are high-strength components that are manufactured via an extrusion process. Here hot steel billets are passed through extruded metal, allowing them to be shaped in the correct dimensions. Designed without any welds or seams, the ASME SA 312 Seamless Pipe is utilized across high-temperature setups. These pipes have enhanced strength and outstanding load-bearing capacity. They have a 20% higher pressure-holding capacity as compared to welded pipes within this grade. The ASTM A312 Cold Draw Seamless Pipes are processed further after the hot rolling procedure. As the pipes are run over dies, their resistance and surface finish are enhanced, giving them outstanding properties. A312 Welded Pipes offer an excellent cost-effective solution compared to seamless pipes. These pipes are produced by rolling sheets or strips and welding them in place following standard welding procedures. Our institution keeps stocks of pipes of different shapes and sizes allowing you to choose quality assured products.
