Sanitary Stainless-Steel Tubing Manufacturer in China
Sanitary tubing is made with polished stainless steel and manufactured according to ASTM standards. The stainless material is composed of various elements such as manganese, carbon, sulfur, phosphorus, nickel, silicon, iron, and chromium. The material strip for a sanitary tube is usually processed with a cold-rolled technique to provide excellent weldability enhancement. This tubing is usually made with the 304 and 316 grades of austenitic stainless steel, which both have a high-temperature tolerance and good strength features.
TuoLian is a leading manufacturer of sanitary SS tubes with wide-diameter size options. We support custom-made SS tubing products. We have a volume stock of SS sanitary tubing in our warehouse and can are ready to ship quickly.
