Spiral pipe is made by rolling low-carbon carbon structural steel or low alloy structural steel strip into a tube blank according to a certain helical angle (called forming angle), and then welding the pipe seam. It can be made with a narrower strip Steel produces large diameter steel pipes. Its specifications are expressed by outer diameter * wall thickness….
Read MoreCritical components of alloy steel and thick parts must be preheated before welding. The purpose of preheating the spiral steel pipe before welding is as follows: (1) Preheating can slow down the cooling rate after welding, make hydrogen diffuse in the weld metal and escape, and avoid cracking caused by hydrogen. It can also reduce the degree of hardening…
Read MoreCarbon steel seamless tube is divided into: 1. Low carbon steel seamless tube Low carbon steel tube is carbon steel with a carbon content of less than 0.25%, including most ordinary carbon structural steels and some high-quality carbon structural steels, most of which are used for engineering structural parts that do not require heat treatment. Some are also carburized…
Read MoreStainless steel seamless pipe is a long strip of steel with a hollow section and no seams around it. The thicker the wall thickness of the stainless steel seamless pipe, the more economical and practical it is, and the thinner the wall thickness, the higher its processing cost will be. Stainless steel seamless pipes are very similar to cs…
Read MoreThe seamless tube is formed in one piece, directly pierced from round steel, without welds on the surface, and has a wide range of applications. Because of the special processing of seamless steel tubes, carbon structural steel, low alloy structural steel, etc. are generally used for production, and its output is large, and it can also be customized according…
Read MoreAmong the many pipeline materials, the most practical one is seamless pipe (SMLS), which is a relatively powerful pipeline material, not only because of the wide range of application fields and scope of this pipeline material, but more importantly, Because the quality of seamless steel pipe is very good, the quality of seamless steel pipe is the reason why…
Read MoreSpiral welded pipe (ssaw) is a kind of steel pipe that combines low-carbon and environmentally friendly alloy structural steel and low-alloy structural characteristics into pipe material and electric welding. How can the reliability of the spiral pipe be improved in the process of adoption? When we store it, we need to ensure the upper block and the lower pad,…
