Spiral 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 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 More1. Spiral submerged arc welded steel pipe (SSAW) and longitudinal submerged arc welded steel pipe (LSAW) In the 1950s and 1960s, spiral steel pipes were widely used in oil and gas pipelines. In the 1970s and 1980s, they were severely challenged by longitudinal submerged arc welded steel pipes (LSAW steel pipe) and ERW steel pipes. So far, spiral steel…
