ERW (Electric Resistance Welded) Pipes

ERW pipes are manufactured by welding steel plates or coils longitudinally using electric resistance welding. This process creates a continuous seam along the length of the pipe, making it suitable for various applications due to its consistent quality and cost-effectiveness.

Grades:

1. IS 3589:
   • Grade FE 330, FE 410: Standard grades for ERW pipes in India.
2. ASTM A53:
   • Grade B: Commonly used for structural and pipeline applications.
3. API 5L:
   • Grades B, X42, X52: Used for oil and gas pipelines and other high-pressure applications.

Sizes:

• Nominal Pipe Size (NPS): Typically ranges from 1/2 inch to 24 inches
• Wall Thickness: Specified in schedules (SCH) or as a specific dimension

Applications:

1. Construction: Used for structural supports, scaffolding, and framework.
2. Water Supply: Suitable for water distribution systems and plumbing.
3. Oil and Gas: Employed in pipelines and other infrastructure requiring reliable and cost-effective piping solutions.

ERW pipes are known for their uniformity, cost-effectiveness, and suitability for a wide range of applications, making them a popular choice in both industrial and residential projects.
