Spiral steel pipe is a spiral seam steel pipe made of strip coil plate, extruded by constant temperature and welded by automatic double-wire submerged arc welding. The spiral steel pipe will send the strip into the welding pipe unit, roll through the multi-channel roll, the strip gradually rolled up to form a circular tube blank with an open gap, adjust the pressure of the extrusion roll, so that the weld gap is controlled in 1~3mm, and the two ends of the welding joint are flush.
Cold drawing machine is a kind of equipment commonly used in the production of rebar, mainly used for steel processing and finishing. Hot rolling mill is another equipment in addition to cold drawing machine, which is mainly used for the production of rebar. The billet is heated at a high temperature and then rolled through a CNC roller. Cutting machine is another common type of rebar production equipment, mainly used to cut rebar to the required length. The rebar is cut by a high-speed rotating saw blade or other cutting tool. Bending machine is a kind of less used rebar production equipment, mainly used for bending and processing rebar. The rebar is bent and machined by using a variety of molds.
Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
