ASTM A312 Pipe

ASME SA312 Seamless Pipe and A312 Welded Pipes

The ASTM A312 grade pertains to the standard classification for stainless steel pipe grades. The ASTM A312 Pipe incorporates alloying elements such as chromium, nickel, copper, molybdenum, among others, providing exceptional tolerance and resistance to corrosive and oxidative environments, even in stress-inducing conditions. This versatile grade encompasses seamless variations, a spectrum of heavily cold-worked welded austenitic stainless steel, and straight-weld pipe modules.The ASTM A312 Schedule 40 Pipe is specifically crafted for use in high-temperature applications and is frequently employed in systems with moderate pressure. Identified as a common schedule in the industry, the sch 40 pipe is widely available.

The ASME SA12 Pipe is categorized as a pressurized vessel pipe grade tailored for elevated pressure and temperature setups. These modules exhibit robust strength and are resistant to bending or distortion under various circumstances.

The high-strength components in the ASTM A312 Seamless Pipes of this grade are produced through an extrusion process. In this method, hot steel billets are passed through extruded metal, shaping them into the correct dimensions. Utilized in high-temperature settings, the ASME SA 312 Seamless Pipe is designed without welds or seams, offering enhanced strength and exceptional load-bearing capacity. With a 20% higher pressure-holding capacity compared to welded pipes in the same grade, these pipes are reliable.

The ASTM A312 Cold Draw Seamless Pipes undergo further processing after the hot rolling procedure. Running the pipes over dies enhances their resistance and surface finish, resulting in outstanding properties. A cost-effective alternative to seamless pipes, A312 Welded Pipes are produced by rolling sheets or strips and welding them in place using standard welding procedures. Our institution maintains stocks of pipes in various shapes and sizes, ensuring you can choose from quality-assured products.
