S

Manufacture technology process of Inox seamless tube:

Steel making--Rolling of Round bars--bore a hole--cold drawing--Bright annealing--inner surface polishing

--outer surface polishing--test and inspection--packing and storage.

Due to the customer requirements and produce techonology of sanitary wary inox seamless tubes,

form the character of sanitary ware stainless steel pipes:

corrosion resistance, waterproof, tensile strength, meanwhile, possess the high precision of specifications

and good brightness of inner and outer surface. And provide an excellent electromagnetic shielding

material of equipment.
