  • Seamless square pipe Q195 Q235 Q345 Q215 Square and rectangular

    Seamless square pipe Q195 Q235 Q345 Q215 Square and rectangular

    Introduction Straight seam steel pipe is a steel pipe whose weld seam is parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, transformer cooling oil pipe and so on. Longitudinal welded pipe has simple production process, high production efficiency, low cost and rapid development. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. A narrower blank can be...

  • Spiral steel pipe Large diameter ERW seamless welded spiral

    Spiral steel pipe Large diameter ERW seamless welded spiral

    Introduction Spiral steel pipe is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. The spiral steel pipe feeds the strip steel into the welded pipe unit. After rolling by multiple rollers, the strip steel is gradually rolled up to form a round tube blank with an open gap. The reduction of the squeeze roll is adjusted to control the weld gap at 1~ 3mm, and make both ends of the welding jo...
  • Hot expanded steel pipe seamless tubing expanded diameter tube

    Hot expanded steel pipe seamless tubing expanded diameter tube

    Introduction Hot-expanded steel pipe refers to a steel pipe with relatively low density but strong shrinkage, and a waste pipe finishing rolling process in which the diameter of the pipe is enlarged by the cross-rolling method or the drawing method. In a relatively short period of time, thickening steel pipes can produce non-standard and special types of seamless pipes, with low cost and high production efficiency, which is the development trend of the international pipe rolling field. The tw...
  • Fertilizer steel pipe/tube 20# 16mn, 15CrMo Fertilizer Special pipe

    Fertilizer steel pipe/tube 20# 16mn, 15CrMo Fertilizer Special pipe

    Introduction Fertilizer steel pipes are divided into general boiler tubes and high-pressure boiler tubes according to the high temperature performance they bear. Regardless of general boiler tubes or high-pressure boiler tubes, they can be divided into various steel pipes according to their different requirements. Fertilizer special steel pipes are mainly used to manufacture high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel high-pressure seamless ...
  • Square rectangular steel pipeQ195 Q235 Q345 Square and rectangular

    Square rectangular steel pipeQ195 Q235 Q345 Square and rectangular

    Introduction Square tubes are classified according to their cross-sectional shapes: simple cross-section square tubes: square tubes and rectangular tubes. After the process is processed, it is rolled into strip steel. Generally, the strip steel is unpacked, flattened, crimped, and welded into a round tube, then the round tube is rolled into a square tube, and then cut to the required length. According to the production process, the square tube is divided into: hot-rolled seamless square tube,...
  • Rectangle pipe Q195 Q235 Q345 Q215 Square and rectangular

    Rectangle pipe Q195 Q235 Q345 Q215 Square and rectangular

    Rectangular pipe is a kind of hollow square section light thin-walled steel pipe, also known as steel refrigerated bending section. It is a section steel with square cross-section shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, which is formed by cold bending and then high-frequency welding. Except for the increased wall thickness, the corner size and edge flatness of the hot-rolled extra-thick-walled square tube reach or exceed the level of the resistance welded cold-formed square tube. Classification of rectangular pipes: steel pipes are divided into seamless steel pipes and welded steel pipes (seamed pipes) hot-rolled seamless square pipes, cold drawn seamless square pipes, extruded seamless square pipes, and welded square pipes.
