Submerged arc welding (SAW) is one of the most efficient mechanized welding methods today. Its full name is automatic submerged arc welding, also known as automatic arc welding under the flux layer. Submerged arc welding technology is ideal for important applications such as pipelines, pressure vessels and storage tanks, rail manufacturing and large-scale construction. Available in the simplest form…
Read MoreStructural seamless pipe (GB/T8162-2008) is a kind of seamless steel pipe used for general structure and mechanical structure. The fluid seamless steel pipe standard applies to seamless steel pipes that transport fluids. In addition to carbon (C) elements and a certain amount of silicon (Si) (generally no more than 0.40%) and manganese (Mn) (generally no more than 0.80%, higher…
Read More1. Use of seamless steel pipes for structures: seamless steel pipes for such structures are now more suitable for general structures and their mechanical equipment structures. Compared with others, the quality of such seamless steel pipes is There are some practical differences. 2. Use of seamless steel pipe for fluid transportation: This type of seamless steel pipe is widely…
Read MoreThe hot extrusion process of seamless steel pipe is a pressure forming method, which is to place the tube blank in a pressure-resistant container, and apply external force to cause the tube blank to plastically deform under the state of three-dimensional compressive stress. During extrusion, the tube blank is in a state of three-way compressive stress, so it can…
Read MoreAlloy tubes are divided into structural seamless tubes and high-pressure heat-resistant alloy tubes. Mainly different from the production standard of alloy pipe and its industry, annealing and tempering of alloy pipe changes its mechanical properties and achieves the required processing conditions. Its performance is higher than that of ordinary seamless steel pipes, and its chemical composition contains more Cr,…
Read MoreThe relationship between welding speed and weld quality should be understood dialectically and cannot be ignored. It is mainly reflected in the heating stage and the crystallization stage. 1. Heating stage Under the condition of high-frequency straight seam welded pipe (erw pipe), the edge of the tube blank is heated from room temperature to the welding temperature. During this…
