ERW Steel Pipes and Tubes

About ERW (Electric Resistance Welded) Steel Pipes and Tubes:

The concept of ERW (Electric Resistance Welded) Steel Pipes and Tubes was born in 1920 however, the actual procedure of galvanization took place in 1962.

Creating:

ERW (Electric Resistance Welded) Pipes and Tubes are made from strips of hot-steel. The steel is first flattened and placed into furnace allowing to pass through the welding electrodes. Additional the electrodes which are copper disk kind are connected with the secondary revolving transformer assembly which assists to contact on each side of the seam and temperature are raised to the welding point. The outside flash is removed as the tube leaves the electrodes and the inside flash is wiped out by an air hammer after the tube has been cooled. This formation is known as Electric Resistance Welded or ERW Tube/Pipe.

Sizes and Shapes:

It is accessible in various sizes and shapes to cater customer specifications. Generally, ERW Steel Tube is available in the variety from 2 3/8 inch to 24 inch outer diameter in a variety of lengths up to 100 feet. ERW pipe is cheaper and stronger than seamless steel pipes. It is very best suited for line pipes.

Qualities:

Before reaching the market place, ERW steel tubes and pipes are processed via several tests including ultrasonic weld inspection, hydro-test, bevel check, micrometer check, ring gouge and straightness evaluation to ensure its quality.

Usage:

ERW steel tubes are used in numerous heavy industrial applications like - fencing, scaffolding, line pipes, engineering purposes, oil business, industrial construction, agricultural industry and the housing business.
