Abstract
The production process of composite zinc-coated steel pipe with stainless steel lining belongs to the field of metal processing technology. The production process includes trimming inside wall of thezinc-coated steel pipe, painting adhesive to outer wall of the stainless steel pipe, inserting the stainless steel pipe into the zinc-coated steel pipe, hemming and sealing two ends, leading steam into the stainless steel pipe to heat and pressurize, heating the zinc-coated steel pipe from outside electrically to combine two layers of steel pipe firmly. The composite pipe may be used in city water supply to raise water quality and used to replace stainless steel pipe or copper pipe as industrial conveyance pipe.
