The High-Frequency Longitudinal Seam Welded Steel pipe is also called ERW steel pipe, it's manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.


High-security welding seam: as a result of special welding method of melting of the parent metal together without filler metal, the welding property is better and the welding seam is much smaller than spiral welded pipes.

Cost effective and short production period

A wide range of thickness/diameter ratio, covering hundreds of specification

In –line inspection and testing


Casing and tubing: lined inside drilling well. Seamless pipes use to be the only choice for lining pipes inside drilling well, but as the worldwide acknowledgement of ERW pipe’s high-quality weld seam and the cost-effective, more and more projects have been choosing ERW instead of seamless pipe.

Constructional structural pipes(round, square and rectangular): round, square and rectangular ERW structural pipes are widely used in frameworks of shopping centres, theatres, airports, bridges, workshops etc.

Low-pressure flow transmitting: ERW pips are also used in water supply; cooling water supply for plants and equipment; low pressure thermal distributing; coal slurry transportation and more.

Pipes for raw materials in the manufacturing industry: automobile vent-pipe; low and intermediate pressure boiler pipes; bulk matters transportation pipes.

Other application: piling pipes, furniture fabricating and more.
