Xinyue Steel Group is a leading supplier of high-quality steel pipes and tubes for various industries worldwide. One of its flagship products is the API 2H Gr.50 pipe, which is specifically designed for offshore applications in harsh environments. API 2H Gr.50 is a grade of steel that meets the American Petroleum Institute (API) Specification 2H standard. This standard covers…
Read MoreSpiral pipe (SSAW) is a 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. How to increase the stability of spiral steel pipe 1) Small and medium-sized steel bars, wire rods, steel bars, medium-caliber steel pipes, steel wires, and wire ropes can be stored…
Read MoreSeamless 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 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 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…
