ERW Steel Pipes

What is ERW Pipes?

Electric Resistance Welded (ERW) pipe is a type of steel tubing created through a high-frequency induction welding process. The manufacturing process involves cold-forming a steel strip into a cylindrical shape and then passing an electric current between the two edges. This current heats the steel to a point where the edges fuse under pressure, creating a strong and uniform bond without the need for filler materials.

Pipe Ends: beveled, straight cut, saw cut, and torch cut

Surface: Lightly oiled, Hot dip galvanized, Electro galvanized, Black Coating, Bare, Varnish coating/Anti rust oil, Protective Coatings (Coal Tar Epoxy,  Fusion Bond Epoxy, 3-layers PE)

Packing: Plastic plugs in both ends, Hexagonal bundles of max. 2,000kg with several steel strips, Two tags on each bundle, Wrapped in waterproof paper, PVC sleeve, and sackcloth with several steel strips, Plastic caps.

Test: Chemical Component Analysis, Mechanical Properties (Ultimate tensile strength, Yield strength, Elongation), Technical Properties (Flattening Test, Bending Test,  Hardness Test, Impact Test), Exterior Size Inspection, Hydrostatic Test, NDT TEST ( ET TEST, RT TEST, UT TEST)

JIS G3452 SGP, JIS G3454 STPG370, STPG410, JIS G3101 SS400

The Main Applications of ERW Pipes

ERW pipes are the best ideal for several industries.

1.Oil and Gas Industry

The ERW steel pipe is often present in oil and gas extraction sites, used for transporting oil, gas.
Additionally, their resistance to corrosion makes them last longer, enabling oil and gas companies to reduce maintenance costs.

2. Water Supply and Irrigation

Water supply systems favor ERW pipes, especially in those handling and transporting water and other potentially corrosive elements. The smooth interior of the pipes also helps in managing water flow, running smoothly, and minimizing friction and pressure drops.

3. Construction Industry

ERW steel pipes as structural support in buildings, bridges, and other infrastructure projects. Their high strength allows them to withstand heavy loads, making them ideal for use in columns, beams, and trusses on construction sites.

4. Power Plants

Power plants, both thermal and nuclear, use ERW pipes to transport coolant fluids, such as water or steam within the plant.
In nuclear plants, these pipes are used as casing or containment for fuel rods, serving as a barrier.
On the other hand, these pipes are used in thermal power plants to cool systems and steam lines.
