Stainless Steel Seamless Pipe is a tubular product without welded seams, produced from solid round steel through piercing, rolling or drawing processes. It is suitable for conveying high-temperature, high-pressure and corrosive media.
Product Description
Stainless Steel Seamless Pipe uses stainless steel round billets as raw material. It is produced through heating, piercing, rolling and sizing processes without any welding involved, giving the pipe body consistent integrity.

FAQ
Q: What is the difference between Stainless Steel Seamless Pipe and welded stainless steel pipe?
A: Seamless pipe is produced by piercing and rolling a solid round billet, with no weld seam in the pipe body, offering better overall consistency and suitable for high-pressure and highly corrosive conditions. Welded pipe is made by rolling and welding steel plate or strip, with differences in microstructure and properties between the weld zone and base metal, suitable for general service conditions.
Q: What is the difference between 304 and 316 stainless steel seamless pipe in use?
A: 304 is a general-purpose 18/8 stainless steel, suitable for general corrosive environments. 316 adds molybdenum on the basis of 304, providing better resistance to chloride corrosion, commonly used in marine environments and chloride-containing media.
Q: Can this product be used in high-temperature environments?
A: Yes. Austenitic stainless steel seamless pipe can be used in high-temperature service. Grades such as TP304H, TP316H and TP321H are suitable for applications where creep and stress rupture properties are important.
