Description:
ERW steel pipe is straight weld pipe, electric resistance welding, the abbreviation for ERW for transporting oil and natural gas vapor liquid objects, can meet the requirements of high and low pressure, the transport in the world with pipe sector accounted for a pivotal position.
ERW tube is a "high frequency resistance welded steel pipe", and the common welded pipe welding process is not the same, the welding seam is made from the steel body of the base metal, the mechanical strength is better than the general welded pipe

ERW pipe is due to the use of hot-rolled coil as raw material, uniform wall thickness can be controlled at about +- 0.2mm, the two ends of the steel pipe according to the APL standard and GB / t9711.1 standard, end trimming hit groove, fixed length delivery and other advantages. In recent years, the natural gas pipeline network engineering and gas companies have been widely used ERW pipe as the main pipe network of the city.
Applications:
The pipe is for Fluid transport and Construction mostly used in industries as Coal gas, Steam, Water,
Petroleum, Natural gas.
Competitive Advantage:
Our factory is near to raw material market and high-speed way, the producing cost is low.
Our factory have long history for trading ERW steel pipe, with large stocks.
We always cooperate with famous project and companies.
