The general application of thick-walled seamless tubes must do the corresponding anti-corrosion and anti-rust treatment work. The general anti-corrosion work is divided into three processes: 1. Anti-rust treatment of pipes. Before painting, the surface of the pipeline should be cleaned of oil, slag, rust, and zinc dust. The product quality standard is Sa2.5. 2. After the anti-rust treatment on…

Read MoreCarbon steel welded pipes are mainly divided into three processes: electric resistance welding (ERW), spiral submerged arc welding (SSAW) and straight seam submerged arc welding (LSAW). The carbon steel welded pipes produced by these three processes have their own positioning in the application field because of their different raw materials, forming processes, caliber size and quality. 1. Straight seam…
Read MoreCarbon steel black pipe is uncoated steel, also known as black steel. The dark color comes from iron oxide that forms on its surface during the manufacturing process. When a steel pipe is forged, a black scale forms on its surface, giving it the finish seen on this type of pipe. Carbon steel galvanized pipe is steel covered with…
Read MoreThe outer coating of welded pipe FBE fused epoxy powder (FUSION BOND EPOXY) anti-corrosion steel pipe is a new type of anti-corrosion coating developed in the past 30 years. The coating has the characteristics of simple coating operation, no pollution, good impact resistance and bending resistance, and high temperature resistance, and has been widely used abroad. Powder coating is…
Read MoreERW 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….
