Seamless tube production equipment
There are many kinds of seamless tube (smls) production equipment according to the seamless steel tube production process. However, regardless of the rolling, extrusion, top pressing or spinning seamless steel tube manufacturing process, the billet heating equipment is inseparable, so the billet ...Read more -
What three processes are included in the heat treatment of carbon steel tubes?
According to different conditions, the metal material is heated to a suitable temperature and kept warm, and then cooled in different ways to change the metallographic structure of the metal material and obtain the required structural properties. This process is usually called metal material heat...Read more -
Welding method of spiral steel pipe
Spiral pipe is a spiral seam welded pipe made of strip steel coil as raw material, extruded at regular temperature, and welded by automatic double-wire double-sided submerged arc welding process. The welding method of submerged arc automatic welding is the same as manual welding in that it still ...Read more -
Characteristics and technological process of steel pipe cold processing
Cold processing of steel pipes (such as seamless tubes) includes methods such as cold rolling, cold drawing, cold tension reduction and spinning, which are the main methods for producing precision thin-walled and high-strength pipes. Among them, cold rolling and cold drawing are commonly used hig...Read more -
