TP316L Stainless steel seamless pipe, also known as 1.4435 seamless stainless steel pipe or S31603 stainless steel seamless pipe, is an austenitic chromium-nickel-molybdenum stainless tube with low carbon content.
This kind of pipe are widely used in cellulose industry, textile industry, oil and boiler industry, etc.
TP316L pipe is usually used for applications that require the high strength, toughness and workability, coupled with increased corrosion resistance.
Comparing with 304 stainless, TP316L seamless pipe contains higher percentages of molybdenum and nickel.
Sheye Metal is a leading manufacturer and supplier of TP316L stainless steel seamless pipe.
Sheye Metal provides a lot of processing services, including cutting to length, polishing surface, punching, painting, etc. 1.4435 Stainless steel seamless pipes are inventoried in full size, ranging from 6.0mm to 1219mm.
We are good at manufacturing thin stainless seamless pipe, thick seamless stainless pipe and large diameter TP316L pipe.
The most common length of TP316L stainless steel seamless pipe we manufacture includes 5.8m, 6.0m, 11.8m, 12m, 12.6m. And the maximum length of TP316L seamless stainless steel pipe is 18m.
With b technical force, advanced equipment and skilled craftsmanship, Sheye Metal can manufacture TP316L stainless steel pipe and good quality is guaranteed. For metal, we are serious.
