Process of stainless steel pipe tube:

Features of stainless steel tubes:

1)characters such as Safety, health, environmental protection

2)economy applicable, good surface

3)the resistant to corrosion

4)less weight than bars, thickness and out diameter so variously

5)easy cutting, huge deformation

6)tensile strengthen and good be flexible etc.

Applications & Usage of seamless stainless pipe

as Line pipe, boiler pipe, mechanical structure, hydraulic prop pipe, gas pipe, geological pipe, chemical pipe
(high pressure chemical fertilizer pipe, oil cracking pipe) and tube for ships, etc
decoration,building,construction,water pipe,petroleum, chemical industry, chemical fiber, smelt, medical machinery,
paper making,Heat preservation and refrigeration, mechanical equipment, food, electricity, water conservancy,
architecture, aerospace, navigation shipbuilding, environmental protection and boiler heat exchanger
