2),Process control:follow the process chart adding our workers’ care
1),Inspection& Test
Direct-reading Spectrum Instrument analytic for chemical composition, Yield Strength, Tensile Strength, Elongation, Hardness Test, Flattening Test, Flaring Test, Eddy Current Test, Ultrasonic Test, Hydrostatic Test, Corrosion Test, etc.
Parts of workshop:
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,good welding and anti-pot corrosion
6)tensile strengthen and good be flexible etc.
