304 Thick Wall Stainless Steel Seamless Pipe
304 is a kind of universal stainless steel, which is widely used in the production of equipment and parts requiring good comprehensive performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel.
The steel pipe with the ratio of outer diameter to wall thickness less than 20 is called thick wall steel pipe.

Advantages Of Seamless Tubes & Pipes
A. Heavy and thick wall thickness
B. No weld seam. Generally be considered as better properties and corrosion resistance
C. Better ovality, or roundness
