ASTM A213 TP321 Seamless Stainless Steel Pipe

Seamless stainless steel pipes are seamless tubes made from stainless steel, providing a smooth and continuous structure without any welded joints. They are manufactured through a process called seamless pipe manufacturing, where a solid cylindrical billet of stainless steel is heated and pierced to create a hollow tube. Seamless stainless steel pipes offer several advantages, including high corrosion resistance, superior strength, and enhanced durability. They are widely used in industries such as oil and gas, petrochemical, power generation, and automotive. Due to their seamless nature, they minimize the risk of leaks and provide excellent fluid flow characteristics, making them ideal for critical applications.

Stainless steel pipe is a multi-purpose structural steel pipe made of stainless steel, which has the characteristics of strong corrosion resistance, high strength, cleanliness and stain resistance. Stainless steel pipes are widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components.

Stainless Steel Seamless (SMLS) pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, Seamless Pipes are perceived to be stronger and more reliable. Historically, seamless pipe was regarded as withstanding pressure better than other types and was often more available than Welded Pipe.
