ERW (Electric Resistance Welded) pipes are a type of pipe manufactured using the electric resistance welding process. In this method, metal sheets or strips are cold-formed into cylindrical shapes, and then the edges are welded together using electrical resistance to create a pipe. ERW pipes are known for their high efficiency, precision, and relatively low production cost.
Uses of ERW Pipes:
Oil and Gas Industry:
- Used for transporting oil, gas, and other fluids due to their strength and durability.
Water Supply Systems:
- Used in water pipelines and sewage systems because of their resistance to corrosion and high pressure.
Automotive Industry:
- Employed in the manufacture of vehicle frames, exhaust systems, and other structural components.
Construction:
- Utilized in building scaffolding, structural supports, and fencing due to their strength and ease of fabrication.
Agriculture:
- Used in irrigation systems, water wells, and other agricultural infrastructure.
Mechanical and General Engineering:
- Employed in manufacturing machinery, equipment, and general-purpose applications requiring reliable and cost-effective piping solutions.
