Definition of ERW steel pipe

What is an ERW Pipe?

A pipe formed by Electric Resistance Welding or ERW having one vertical seam without addition of any metal is called ERW pipes or tubes. It can be available in varied diameters and wall thickness. The sizes of pipes ERW pipes can range from 2 3/8 inch to 24 inch outer diameter and length can be over 100feet.

How EWR Pipe is made?

First the iron is flatten then place it into roller to form a tube and passes through a welding electrode made of copper disk which is connected to a revolving transformer. When the electrodes contact each side, the temperature is increased to the welding point. Once the tubes leaves the electrodes, the inside flash is removed by after colling the tube with a hammer and the outer flash by a cutting tool. The surface finish could be either bare or coated.

Qualities of ERW Steel Pipes:

Before reaching the market place, ERW steel tubes and pipes are routed through numerous tests including a hydro-test, an ultrasonic weld inspection, bevel check, micrometer check, straightness evaluation, and ring gouge to ensure its quality. The high performance ERW steel pipes and tubes possess better corrosion resistance, deformable and tougher.

Usage of ERW steel pipes & tubes:

These pipes are used in fencing, line pipes, oil country tubular, scaffolding, water and gas conveyance, structural, engineering purpose. There has been a tremendous increase in the production of ERW steel tubes due to growing demand in oil & gas industry, infrastructure and automobile usages.

Based on the end user customer's requirement, ERW (electric resistance welded) steel pipes and tubes are available in various qualities, wall thicknesses, and diameters of the finished pipes. While manufacturing ERW steel pipes, only high-quality, continuous-cast, fully killed, control-rolled, fine-grain, low-carbon steel is used. High performance ERW steel pipes and tubes possess high strength corrosion resistance, high deformability, high strength and high toughness.
