Stainless Welded Steel Pipe

Stainless Welded Steel Pipe

Product Details


2 Inch 201 Round 316l pipe Welded 304 Stainless Steel Pipe 316


1. Our stainless steel tubes pipes are treated by bright annealing, inside weld bead removing, precise polishing. The roughness of tubes could be under 0.3μm.
2. We have the non destructive testing ( NDT ), eg. online eddy current inspection and hydraulic or airtightness testing.
3. Thick welding, good appearance.The mechanical properties of tube could be tested.
4. The raw material is from Taigang, Baosteel, etc.
5. And Our tubes are certificated by AD 2000-W0, PED 2014/68/EU, ISO 9001 : 2015.
