Stainless steel pipe features

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, Baogang, Zhangpu and so on.

5. And Our tubes are certificated by AD 2000-W0, PED 2014/68/EU, ISO 9001 : 2015.

6. Full material traceability is guaranteed during the manufacturing process.

7. Polished tube is supplied in individual plastic sleeves with capped ends ensuring optimum cleanliness.

8. Internal Bore: Tubes have a smooth, clean and crevice free bore.
