Professional Design Stainless Steel Rectangular Pipe - ERW steel pipe/tube Electric Resistance Welding oil natural gas – Lu

Introduction

“ERW steel pipe” is a straight seam resistance welded pipe, abbreviated as ERW. It is used to transport oil, natural gas and other vapor and liquid objects. It can meet various requirements of high and low pressure, and it occupies a pivotal position in the field of transportation pipes in the world. Welded pipes are round pipes welded by steel plates, which are divided into high frequency resistance welded pipes (ERW welded pipes), straight seam arc welded pipes (LSAW), and spiral welded pipes. The ERW steel pipe has the advantages of using hot-rolled coil as the raw material, the uniform wall thickness can be controlled at ±0.2mm, the two ends of the steel pipe are in accordance with the American Apl standard or the GB/T9711.1 standard, the end is beveled, and the length is delivered to a fixed length. advantage.
