TP304 Stainless Steel Seamless Pipe
TP304 Stainless steel seamless pipe, also know as 1.4301 stainless seamless pipe or S30400 stainless steel seamless pipe, is the standard austenitic chromium-nickel stainless pipe. It has high corrosion resistance and easy formability. But it can’t resist intergranular corrosion. TP304 Stainless steel seamless pipes are widely used in chemical and petrochemical industry, oil industry, and equipment for foodstuff industry. We inventory TP304 stainless seamless pipe with full size. The outside diameter we manufacture ranges from 6.0mm to 1219mm. We are good at manufacturing long stainless steel seamless pipes, such as 11.8m, 12m, and 12.6m. The maximum length we manufacture is 18m. Our TP304 stainless steel seamless pipes are exported to many countries, like USA, Germany, UAE, Japan, Italy, India, Korea, Myanmar, Spain, Oman, Algeria, Czech France, Singapore, Indonesia, Netherlands, Belgium. Canada, Malaysia, etc. Sheye Metal provides a lot of processing services, including cutting to length, polishing surface, punching, painting, etc. With strong technical force, advanced equipment and skilled craftsmanship, Sheye Metal can manufacture TP304 stainless steel seamless pipe and good quality is guaranteed. For metal, we are serious.
