• Right Way to Save Spiral Pipe

    proper way to preserve spiral pipe1) storage space spiral steel pipe products or warehouse, should be selected in clean, smooth drainage area, away from harmful gases or dust in factories and mines. the presence on the ground to clear the weeds and all the debris, keeping a clean steel2) in a wareho
  • Difference between ERW Steel Pipe and UOE Steel Pipe

    first, the raw materials and production capacity differenceerw steel pipe material is hot-rolled coil, uoe steel pipe material is hot-rolled steel. therefore, erw steel pipe can achieve a continuous pipeline operations, high production efficiency, low production costs; and uoe steel pipe is used to
  • Advantages and Disadvantages of Electric Resistance Welding

    electric resistance welding method is a combination of the workpiece to exert pressure through the electrode, the use of current through the resistor thermal contact surfaces and adjacent areas generated by joint welding.advantage of electric resistance welding1, nugget, always surrounded by a plast
  • Disadvantages of Hot Rolled Steel

    first,after hot rolling, steel internal non-metallic inclusions (mainly sulfides and oxides, and silicate) is pressed into thin slices, delamination (interlayer) phenomenon. layering the steel in the thickness direction of the tensile performance deteriorated significantly, and there may be an inter
