ERW welded pipe is formed by using the skin effect and proximity effect of high-frequency current to rapidly heat the edge of the formed pipe blank to the welding temperature and then extrude and weld it. According to the different feeding methods, ERW welded pipes can be divided into high frequency contact welding and high frequency induction welding. Both…
Read MoreCold rolling refers to the processing of steel plates or strips into various types of steel through cold working such as cold drawing, cold bending, and cold drawing at room temperature. Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Carbon steel pipes are made of steel ingots or solid billets through perforation into…
Read MoreSpiral pipe derusting and anti-corrosion process: Derusting is an important part of the anti-corrosion process of spiral welded pipe pipelines. At present, there are many derusting methods, such as manual derusting, sand blasting and pickling and so on. Among them, manual rust removal, mechanical rust removal and painting rust removal (anti-corrosion brushing oil) are relatively common rust removal methods….
Read MoreSpiral pipe (SSAW) is also called spiral steel pipe or spiral welded pipe. It is made by rolling a low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain helical angle (called a forming angle), and then welding the tube seams. It can produce large diameter pipes from narrower strips. Spiral pipes are mainly…

Read MoreWelding problems are sometimes encountered during the installation of carbon steel tubes. So, how to weld tubes? What should we pay attention to when welding carbon steel tubes? 1. Gas welding Gas welding can be used for welding, which is to mix combustible gas and combustion-supporting gas together, use it as the heat source of the flame, and then…
Read MoreLow temperature carbon steel pipe is a medium carbon structural steel. It has good performance in cold and hot heating, good mechanical properties, low price and wide source, so it is widely used. Its biggest weakness is low hardenability, and workpieces with large cross-sectional dimensions and relatively high requirements should not be used. Cold steel running at low temperature…
Read MoreLow carbon steel is a type of carbon steel. Carbon is present in all steels, and as long as carbon is the predominant alloying element in this steel, the alloy is considered carbon steel. “Low carbon” steel is another name for low carbon steel, and there are other carbon steels with different carbon contents. Which one is better depends…
