ASTM A312 TP304 304L Seamless And Welded Pipe High Temperature
Stainless Steel 304 Pipe is made either seamless or welded. The pipes could be drawn from a single billet as seamless or be welded from a strip or plate. There are different welding methods such as electric resistance welding for smaller pipes and electric fusion welding for pipes with large diameters. TONG CHUANG is a manufacturer of all sizes of 304 pipes.
The Stainless Steel 304 is used for more accurate dimensions with applications that require accurate dimensions whereas the SS 304 Welded Pipe is used for mechanical applications rather than technical applications.
