Electric Resistance Welded (ERW) Pipes Electric Resistance Welded (ERW) pipes are produced from hot rolled steel strips or skelp. They are rolled into respective sizes and welded longitudinally. ERW pipes are used for general construction applications such as plumbing, water transmission, scaffolding and fencing.
Spiral Welded Pipes Spiral Welded Pipes are produced from hot rolled steel strips spirally roll-formed into respective sizes and welded along the edge of the strip. They are used for general construction applications where large diameter pipes are needed , e.g., piling, bulk water transmission, etc.
Seamless Pipes Seamless pipes are produced from billets through a hot draw and extrusion process. They are used for high pressure applications in oil field development and oil production, high temperature applications..
Electric Resistance Welding Machine with Stretched Reduced Mill (ERW-SRM) Pipes ERW-SRM pipes are essentially produced using the ERW process. The pipes are then subjected to tension and reduction forces under moderate temperature conditions to produce virtually seamless pipes.
ERW-SRM pipes are used for medium pressure applications for oil wells, boiler pipes, fluid and gas transmission.
