Carbon 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 uneven wall thickness of the seamless tube(SMLS) is mainly manifested in the phenomenon of uneven wall thickness of the spiral shape, uneven wall thickness of the straight line, and thicker and thinner walls at the head and tail. The influence of continuous rolling process adjustment of seamless tubes is an important factor leading to uneven wall thickness of…
Read MoreAfter the quenching and tempering treatment of seamless pipes, the parts produced have good comprehensive mechanical properties and are widely used in various important structural parts, especially those connecting rods, bolts, gears and shafts that work under alternating loads. But the surface hardness is low and not wear-resistant. Tempering + surface quenching can be used to improve the surface…
Read MoreResistance welding is a method of combining the workpieces and applying pressure through the electrodes, using the resistance heat generated by the current passing through the contact surface of the joint and the adjacent area for welding. Resistance welding is a method in which electric current flows through the contact surface of the workpiece and the resistance heating effect…

Read MoreWhat is a straight seam welded pipe? Straight seam welded pipe is a steel pipe with a straight weld seam parallel to the longitudinal direction of the steel pipe, also known as a straight seam steel pipe, which is made by bending a steel plate or strip and then welding the joints. The production process of straight seam welded…
