There are a few aspects of differences between ERW Pipes and Seamless Steel Pipes. ERW pipe, which is short for electric resistance welding, is used in delivery of liquid, such as fuel, gas and so on, regardless the requirement of pressure. While Seamless Pipe is a kind of steel pipe shaping square and rectangle and having no seam around with hollow cross sections, which is not only used in conveying liquid but also making structural members and machine parts, due to its high anti bending and anti torque strength and impossibly lightness. All in all, ERW Pipes and Seamless Pipes are quite different in use.
