Seamless thin-wall stainless steel water pipe production process

Abstract

The invention discloses a seamless thin-wall stainless steel water pipe production process. The production process comprise the following steps of (1), steelmaking; (2), carrying out a hot rolling ofround steel; (3), peeling and perforation; (4), carrying out a two-roller cold rolling cogging; (5), carrying out a three-roller finish rolling of a finished product pipe; (6), carrying out an ultrasonic cleaning; (7), carrying out a bright annealing; (8), straightening; (9), fixing cutting machine (10), cleaning finished products; (11), detecting; (12), carrying out surface plastic coating; (13),identifying; and (14), packaging and warehousing. Through the steps, the invention provides the seamless thin-wall stainless steel water pipe production process, the production process is simple, andthe inner surface and the outer surface are bright without oxide skins; the seamless thin-wall stainless steel water pipe is high in corrosion resistance and low in roughness of the inner surface andthe outer surface, medium is not easy to adhere, so that secondary pollution to water and other fluids caused by the pipe can be avoided, and when the outer surface is coated with plastic, a heat preservation effect is achieved and the condensation water effect is avoided. The use cost is reduced when thin-walled formation is obtained; the seamless thin-wall stainless steel water pipe can be usedfor replacing a thin-wall stainless steel welding steel tube (GB / T199228.2), and stainless steel clamping-pressing type pipe fittings (GB / T19228.1) can be cooperated with the seamless thin-wall stainless steel water pipe and the usage is safer and more reliable.

Description

technical field [0001] The invention belongs to the technical field of manufacturing seamless stainless steel pipes, and in particular relates to a production process for seamless thin-walled stainless steel water pipes. Background technique [0002] With the continuous development of our country's economy and the improvement of people's living standards, people are paying more and more attention to the problem of domestic water being polluted by bad pipes. There is an urgent need for a clean, safe and durable water supply pipeline to replace the traditional water supply pipeline. Stainless steel pipe has the advantages of well-known corrosion resistance, cleanliness, safety and long life. However, the seamless stainless steel pipes produced by the traditional cold drawing process, aerobic heat treatment and pickling process have not been used in batches in the field of civil water supply due to reasons such as too thick walls, roughness, high cost, and complicated connectio...

Problems solved by technology

However, the seamless stainless steel pipes produced by the traditional cold drawing process, aerobic heat treatment and pickling process have not been used in batches in the field of civil water supply due to reasons such as too thick walls, roughness, high cost, and complicated connection and installation procedures; welded stainless steel pipes are almost It began to be used for water supply pipes years ago, but the welding process determines that the safety is not as good as seamless pipes
