Seamless pipe (SMLS) is a steel pipe made of a single piece of metal with no joints on the surface. It is made of a steel ingot or a solid tube blank through perforation to form a capillary tube, and then hot-rolled, cold-rolled or cold-drawn. The characteristics of seamless steel pipes are different from other steel pipes. They are…
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 MorePiercing is the first process of deformation of hot-rolled seamless steel pipe, and its function is to pierce the solid tube blank into a hollow capillary tube. Due to the surface defects or eccentricity (uneven wall thickness) of the threaded capillary, it is difficult to eliminate or reduce it in the subsequent deformation process. Therefore, the quality of the…
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 MorePrecautions for seamless pipe loading 1. In order to prevent sinking, indentation, scratches and thread damage of the pipe body, it should be hoisted by disk crane, nylon belt or steel wire rope with protective spacer when loading. 2. When hoisting bundled steel pipes, no more than two bundles are allowed to be hoisted at the same time. When…
