| High Light | Sch 80 Stainless Steel 304 Seamless Pipe ，Schedule 80 304 Stainless Steel Pipe ，304 SS Schedule 40 Pipe | ||
Our Stainless Steel 304 Seamless Pipe is manufactured to ASTM A312 TP304 standards, offering exceptional corrosion resistance, high-temperature strength, and dimensional precision. Produced by extruding solid billet without any weld seam, this seamless stainless steel pipe is the preferred choice for critical applications in chemical processing, food & beverage, pharmaceutical, oil & gas, and power generation industries where weld integrity is a primary concern.
Available in a full range of schedules (Sch 10, Sch 40, Sch 80, Sch 160) and sizes from 1/8″ to 24″ NPS, our SS 304 seamless pipe delivers reliable performance in both high-pressure and high-temperature environments.
Stainless Steel 304 is the most widely used austenitic stainless steel grade, known for its excellent formability, weldability, and corrosion resistance. When manufactured as a seamless pipe (per ASTM A312 TP304), the product contains no longitudinal weld seam, eliminating the risk of weld-related failures in critical service conditions.
The seamless manufacturing process involves heating a solid stainless steel billet and piercing it to create a hollow tube, which is then rolled and drawn to achieve precise dimensions. This results in a pipe with uniform wall thickness, superior mechanical properties, and complete material homogeneity.
