Main Products


The company produces large-diameter straight seam steel pipes, thick-walled T-shaped welded coil pipes, bimetallic composite steel pipes, elbows, tees, reducers, forged pipe fittings, and mainly high-pressure thick-walled steel pipes and pipe fittings.

The main issue in producing large-diameter straight seam rolled pipes is welding. As long as they can pass the non-destructive testing, the delivery requirements are relatively broad compared to other products.

The tapered steel pipe has an outer diameter ranging from 60mm to 450mm, with a thickness of 6mm to 40mm and a length of 8 meters. Cone shaped steel pipes are mostly customized for processing, so if customers need to indicate the large head diameter, small head diameter, thickness, length, material, and quantity.
