1. What Are ERW Pipes?

ERW pipes are made by rolling metal strips and welding them longitudinally using electric resistance. This process produces a strong and reliable pipe that is ideal for many industrial applications.

2. ERW Pipe Quality Standards

The quality of ERW pipes is crucial for ensuring their performance and durability. The major standards followed by manufacturers in India include:

• IS 1239 (Part 1): This standard specifies the requirements for mild steel pipes used in plumbing and other general purposes.
• IS 3589: This standard covers high-strength ERW pipes used for water and gas transportation.
• ISO 9001: Many ERW pipe manufacturers in India comply with ISO 9001, ensuring they meet international quality management standards.

Factors Ensuring High-Quality ERW Pipes:

• Material Selection: High-quality steel or carbon steel is used for ERW pipes.
• Precision Welding: The welding process must be performed with high precision to prevent defects.
• Testing and Inspection: Manufacturers conduct stringent tests, including hydrostatic and ultrasonic tests, to ensure quality.

3. ERW Pipe Size Range

ERW pipes come in various sizes, catering to a wide range of industrial requirements. The common size ranges include:

• Outer Diameter (OD): ½ inch to 24 inches
• Wall Thickness: 1.6 mm to 12 mm
• Length: Custom lengths, usually between 6 meters to 12 meters
• Pipe Grades: A, B, X42, X46, X52, X56, and X60 (depending on strength requirements)

These sizes can be customized as per client needs, and different manufacturers offer varying size ranges.
