What is ERW structural pipe?
ERW structural pipe is the abbreviation of electric resistance welded steel pipe. The pipe is made of steel coils with welds running parallel to the pipe. It is one of the most versatile tools in agricultural, industrial and construction activities. The manufacturing process of ERW steel pipes includes HFW. ERW welding includes low frequency welding, medium frequency welding and high frequency welding. It is a kind of pipeline widely used in oil, natural gas, coal gas, machinery, construction, aviation, electric power and other industries.
