TP316Ti Stainless Steel Seamless Pipe

TP316Ti stainless steel seamless pipe, also known as 1.4571 stainless steel seamless pipe, is a austenitic chromium-nickel stainless tube, stabilized with titanium.

Parameter

TP316Ti stainless steel seamless pipe, also known as 1.4571 stainless steel seamless pipe, is a austenitic chromium-nickel stainless tube, stabilized with titanium.

With good corrosion resistance to low content of hydrochloric and organic acids, 316Ti stainless steel seamless pipes are widely used in chemical industry, textile industry, cellulose industry, etc.

All TP316Ti stainless steel seamless pipe we manufacture are free from external and internal surface defects that can be detected by visual examination.

All 1.4571 stainless seamless pipes can be cut to size according to client's requirement. TP316Ti pipes shall be delivered with square cut ends, and the ends shall be free from excessive burrs.

When the wall thickness of these tubes is over 3.2mm, it shall be delivered with beveled ends.

We can supply 316Ti pipes with polished finish, which are inventoried in diameter from 21.3mm to 323.9mm.

We have rich experiences in manufacturing TP316Ti stainless steel seamless pipe in strict accordance with EN10216-5 or ASTM A312/A213, DIN 17456, 17458 and JIS G3459/3463.

Sheye Metal provides a lot of processing services, including cutting to length, polishing surface, punching, painting, etc.

With b technical force, advanced equipment and skilled craftsmanship, Sheye Metal can manufacture 316Ti seamless stainless steel pipe and good quality is guaranteed. For metal, we are serious.
