ERW (Electric Resistance Welded) pipes are a type of steel pipe that is made by fusing flat pieces of steel together longitudinally, using an electric current. The process involves heating the edges of the steel to a melting point and then pressing them together under pressure to form a strong, seamless bond.

Material & Product Testing

Destructive Test:

• Properties of raw materials (coils) such as tensile strength, yield strength, and elongation.
• Bending and flattening test for weld strength and quality.
• Mass of zinc coating (For galvanized pipes).

Non-Destructive Test:

• Dimensional inspection on outside diameter, thickness, and length.
• Visual Inspection on straightness and workmanship
• Zinc-coating test using calibrated electromagnetic meter (For galvanized pipes).

Hydro Testing in accordance with the standard pipe requirements
