Straight seam welded steel pipe includes double-sided submerged arc welded longitudinal welded steel pipe (LSAW pipe) and high frequency electric resistance welded pipes (ERW pipe). The length of straight seam welded steel pipe is mainly divided into fixed length and indefinite length. This is mainly according to customer requirements. The length is generally 6-14 meters. Large diameter straight seam welded steel pipe may require rolling two steel plates, also forming a double weld. Welding matters of straight seam welded steel pipes are classified according to manufacturing methods. Steel pipes can be divided into two categories according to manufacturing methods: seamless spliced steel pipes and electric welded steel pipes.
Straight seam welded steel pipe is a steel pipe made by rolling a certain standard long strip into a round tube shape and straight seam welding by a high-frequency welding unit. The shape of the steel pipe can be round, square or special. Depends on sizing rolling after welding.
Nowadays, we have a wide range of applications for straight seam welded steel pipes, but it is inevitable that rust will occur during use. The rusted straight seam welded steel pipe will affect its normal use, so if you find rust that needs to be cleaned in time, then today I will tell you several ways to clean the straight seam welded steel pipe:
First, we can use a solvent or lotion to clean the surface. This method is very effective for organic matter such as oil or dust on the surface of longitudinally welded pipes.
Secondly, for the rust on the surface, we can use wire brushes and other things to polish the surface of the longitudinally welded steel pipe to achieve the purpose of rust removal.
Spraying can also be used. This method not only completely removes rust, oxides and dirt, but also achieves the required average roughness under the action of the abrasive impact and friction.
