The seamless steel pipe is made by perforating the whole round steel, and the steel pipe without weld seam on the surface is called seamless steel pipe. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and pipe jacking.
It is used to build the main structure of high-rise buildings, such as steel structure frames, stairs, handrails, etc. Its high strength and stability enable buildings to withstand greater loads and external forces, improving the safety and durability of buildings.
Straight Seam Steel Pipe is a high-strength environmental protection steel pipe manufactured by straight seam welding technology. Compared with the traditional steel pipe production process, Straight Seam Steel Pipe does not need the traditional spiral welding process, thus avoiding the consumption of a large amount of welding heat energy, reducing energy waste and carbon dioxide emissions.
Straight Seam Steel Pipe is a steel pipe manufactured by straight seam welding technology. It is made of high-strength steel and has excellent compression and corrosion resistance.
Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, extruded at regular temperature, and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe sends the strip steel into the welded pipe unit, and the strip steel is rolled up gradually after rolling by multiple rollers to form a circular tube billet with an opening gap. Adjust the reduction of the extrusion roller to control the weld gap at 1-3mm, and make both ends of the welding port flush.
The coating of 3PE anticorrosive steel pipe is an epoxy powder anticorrosive coating which is in contact with the surface of the steel pipe...
