219mm Spiral Steel Pipe
219mm spiral submerged arc steel pipe is a spiral seam welded steel pipe with a diameter of 219mm. It has the following characteristics and applications:
Excellent mechanical properties: 219mm spiral pipe has high tensile strength and yield point, its tensile strength can reach more than 500MPa, and its yield point can reach about 300MPa. In addition, it has good plasticity and toughness and can meet the needs of different projects1.
Good corrosion resistance: Made of high-quality steel plates, the surface has been treated with rust removal, coating, etc. It has good corrosion resistance and can be widely used in corrosive media such as acids, alkalis, and salts.
High strength: 219mm spiral carbon steel pipe has high load-bearing capacity and can withstand large pressure and bending stress. At the same time, it also has good seismic resistance and fatigue resistance, and can meet the safety needs of different projects.
