Difference of LSAW,ERW and SSAW
ERW is high-frequency resistance welding straight seam welded pipe; LSAW is submerged arc welding straight seam welded pipe; Both belong to straight seam welded pipe, but the welding process are different. So you can’t say one of them on behalf of the straight seam welded pipe. More common...Read more -
Construction of cement mortar steel pipe

Characteristics of medium carbon steel welding
Medium carbon steel generally refers to the carbon content of about 0.25 to 0.60% carbon steel. Manual arc welding of carbon steel casting and welding of the main features as follows: (1) Base metal near the weld area prone to low plasticity of hardened tissue. The higher the carbon content, plat...Read more -
Carbon Steel Pipe Fittings Production Process
Carbon steel pipe fittings production process is similar to carbon steel tube. ① Blanking The mild steel pipe materials is used primarily for pipe, process, and bars, the shape of the blank to select the cutting method based on the material properties and product. Blank shape, size and other req...Read more -
Tube bending
Metallic materials when external force exceeds the yield limit its materials, will produce permanent plastic deformation, which is the basic principle of the tube bending. Bending the tube, the outer wall due to its stretching and thinning of the medial compression due to thickening, since the re...Read more
