Spiral 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 MoreDue to the increasing bearing pressure of the pipeline, the use conditions are becoming more and more severe, and the service life of the pipeline should be extended as much as possible. In order to improve competitiveness, carbon steel pipe manufacturers should research and innovate in what aspects, and what are the main development directions of spiral welded pipes?…
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 MoreIn the production process of spiral steel pipe, if the production process is unreasonable and the machine parameters are not properly set, there will be deviations, especially for large-diameter spiral steel pipes, which is often referred to as the wrong side phenomenon. During the production of spiral steel pipe, the wrong side occurs from time to time, and there…
Read MoreThe relationship between welding speed and weld quality should be understood dialectically and cannot be ignored. It is mainly reflected in the heating stage and the crystallization stage. 1. Heating stage Under the condition of high-frequency straight seam welded pipe (erw pipe), the edge of the tube blank is heated from room temperature to the welding temperature. During this…
Read MoreASTM A234 standard steel pipe fittings have been widely applied in pipeline systems, it includes carbon and alloy steel material. Grades in ASTM A234: ASTM A234 specification has many grades, such as WPB, WPC, WP5, WP9 WP11, WP12, WP22, WP91 and so on. In these standard Grade WPB is the most common material used for medium and high temperature…
