ERW Pipe

ERW Pipe generally refers to the anti-corrosion treatment of ordinary steel pipes by using special processes to make the steel pipes have the anti-corrosion ability, which is generally used for water proofing, rust prevention, acid and alkali prevention, oxidation prevention and other characteristics. The process of base metal of straight seam anti-corrosion steel pipe includes submerged arc welding ERW Pipe and high-frequency ERW Pipe. The diameter of anti-corrosion submerged arc welding ERW pipe is above 325, and the diameter of anti-corrosion high-frequency ERW pipe is below 426.

 

ERW Pipe is mainly used in water works, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. For liquid transportation: water supply and drainage. For gas transmission: gas, steam, liquefied petroleum gas. For structure: for pile driving pipe and bridge; Pipes for wharfs, roads, building structures, etc.
