What Is ERW Pipe

ERW pipes are generally more cost-effective than seamless pipes due to the manufacturing process.
Welding manufacturing process brings a smoother surface finish which easily reduces friction and improves the flow of fluids.
Precise dimensions and uniform wall thickness ensure consistency and accuracy, beneficial for compatibility with fittings.
ERW pipes are suitable for various applications like high-pressure transmission of fluids or gases.
A wide range of sizes and lengths makes the pipes suitable for different applications.
The pipes an be easily welded and fabricated into various shapes or lengths, providing versatility in different projects.

Applications of ERW Pipes

ERW pipes are broadly used by the industries for their excellent properties, durability, and cost-effectiveness.

The top application areas of ERW pipes include:

Oil Country Tubulars Goods (OCTG)
Construction
Water and Gas Conveyance
Automobile Sector
Power Generation Projects.

The main advantages of ERW steel pipe

High production efficiency: the production of erw pipe has achieved a high degree of automation, capable of large-scale mass production, and can be produced continuously, reducing the downtime.

Cost-effective: due to the high frequency of production down, the unit cost is relatively low, and there is relatively little waste in the production of erw pipes, which saves production costs.

High quality: erw pipe can meet the strict requirements of various projects, its wall thickness consistency is high, the surface is smooth, no defects in the weld, reducing the need for post-processing. And the current technology of erw is relatively perfect, which can guarantee the service life of the pipeline.

High strength and durability: ERW pipe can be applied to a variety of materials, to meet the requirements of different projects, in the oil and gas transport, erw pipeline is showing his advantages.

Environmental protection: ERW pipe in the production process of energy consumption is less, welding using high-frequency welding machine, compared with other welding methods more environmentally friendly.

Manufacturing Process of ERW Pipes

In the Electric Resistance Welding process:

Material Selection and Trimming: Choose the right steel according to the user’s scenario, cut the steel coil into the right size and treat the edges.
Accumulation of materials: The steel plates are connected by machines to facilitate the later forming of the pipe.
Forming: The connected steel sheets are gradually bent into a cylindrical shape through a series of rollers, which are continuously and accurately calculated to ensure that the diameter of the pipe is consistent.
Welding: The edges of the metal strips are welded by a high frequency welding machine, and at the same time pressure is exerted on the pipe by the forming rollers, so that the metal can be fused together when it reaches the fusion point.
Post-welding treatment: Welding beads are trimmed, inside and outside of the weld beads are treated to ensure smooth wall surface of the pipe, and heat treatment is used to eliminate stress and improve mechanical properties. Finally, the pipe is corrected by rollers to ensure that the pipe is within tolerance.
Inspection test: non-destructive testing and hydrotesting are more important pipeline testing methods, which can guarantee that the pipeline meets the requirements.
