ERW (Electric Resistance Welded) Line Pipe is a type of steel pipe commonly used in the oil and gas industry for transporting fluids such as oil, gas, and water. It is manufactured using the electric resistance welding process, where the edges of the steel strip or coil are heated and fused together under pressure to form a welded seam. This article will talk about ERW line pipe.
Characteristics and Advantages of ERW Line Pipe:
1. Smooth surfaces: hot-rolled strip steel is continuously cold formed into smooth-surface, uniform wall pipe for superior coatability and flow characteristics.
2. Stronger, lighter walls: higher strength, lighter gauge steel strip is fused by high frequency electric resistance welders into high toughness steel pipe that meets exacting tolerances and strength specifications.
3. Uniform dimensions and quality: ERW steel pipe products have uniform wall thicknesses made from hot-rolled steel strip. Highly automated processes, combined with continuous non-destructive and visual inspection, and hydrostatic testing.
