What is ERW steel pipe?
ERW steel pipe refers to electric resistance welded pipe. The use of ERW steel pipe. ERW steel pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipe, etc. ERW steel pipe and tubing is available in various qualities, wall thicknesses, and diameters of finished pipe.
Manufacturing process of ERW pipe
Electric resistance welded pipe (ERW) is manufactured by cold forming a steel sheet into a cylindrical shape. An electric current is then passed between the two edges of the steel to heat the steel to a point where the edges are forced to join together, forming a bond without the use of weld filler material.
Plates rolled into pipes and welded using the resistance welding process. Suitable for large diameters.
To complete these processes, various mechanical equipment and welding, electrical control, and detection devices are required, and these equipment and devices are based on different materials. This process requires various reasonable arrangements. The typical process of high-frequency welded pipe is: uncoiling--strip leveling--head and tail cutting--strip butt joint--ring pressure accumulator-forming-welding-clearing --Sizing--Flaw Detection--Fly Cutting--Preliminary Verification--Pipe Straightening--Pipe Processing--Hydrostatic Test--Flaw Detection--Printing and Coating--Finished Products.
High-frequency welding is a welding method in which the workpiece metals are connected to each other by applying resistance heating and forging pressure generated by high-frequency current continuously flowing through the contact surface of the workpiece. It is similar to regular resistance welding, but has a number of important differences.
