Quality assure of stainless steel pipe tube:
1)Basic guarantee:Raw material guarantee,we use the Tsingshan Brand raw material,the quality is good,adding we use the spectrum direct-reading test,our professional
workers &equipments,we could guarantee the tubes is right of the clients' needs.
2)Process control:follow the process chart + our professional workers' care
3)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
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.
