Steel pipe structures currently used in engineering can be classified according to cross-sectional shape, structural form and manufacturing method. According to the cross-sectional shape of the component, the steel pipe structure can be divided into three categories: the circular tube structure (CHS), the square (rectangular) tube structure (RHS) and other shapes. Due to the superiority in appearance and mechanical…
Read MoreThe galvanizing method of seamless pipe (SMLS) shall be hot-dip galvanizing. Size, shape, surface, mechanical properties and process performance inspection should be carried out before galvanizing. Surface quality requirements of galvanized layer: The galvanized layer on the inner and outer surfaces of the seamless steel pipe should be complete, no black spots and air bubbles without zinc plating are…
Read MoreIn the casting and rolling process of seamless steel pipe, one of the important technical indicators to measure the processing quality of seamless steel pipe is straightness. Most seamless pipes need to be straightened, and the oblique roller straightening has high work efficiency and is in the main position. However, for the bending deformation of steel pipe ends and…
Read MoreSpiral pipe (SSAW) is a spiral seam carbon steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. It is mainly used in water supply engineering, petrochemical, chemical, electric power, agricultural Fluid transportation in the fields of irrigation and municipal buildings: water supply, drainage, sewage treatment…

Read MoreThe outer coating of welded pipe FBE fused epoxy powder (FUSION BOND EPOXY) anti-corrosion steel pipe is a new type of anti-corrosion coating developed in the past 30 years. The coating has the characteristics of simple coating operation, no pollution, good impact resistance and bending resistance, and high temperature resistance, and has been widely used abroad. Powder coating is…
Read MoreCold rolling refers to the processing of steel plates or strips into various types of steel through cold working such as cold drawing, cold bending, and cold drawing at room temperature. Carbon steel pipes are divided into two categories: hot-rolled and cold-rolled (drawn) steel pipes. Carbon steel pipes are made of steel ingots or solid billets through perforation into…
Read MoreSpiral pipe (SSAW) is also called spiral steel pipe or spiral welded pipe. It is made by rolling a low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain helical angle (called a forming angle), and then welding the tube seams. It can produce large diameter pipes from narrower strips. Spiral pipes are mainly…
