Plastic-lined steel pipes are made of ordinary carbon steel pipes as the matrix, lined with thermoplastics with excellent chemical stability.
It not only retains the strength of the steel pipe and the traditional connection method, but also gives full play to the characteristics of the plastic material such as corrosion resistance, anti-aging, high wear resistance, non-rust, non-toxic, and smooth inner wall through different modifications of the plastic material.
Product specification
The modified corrosion-resistant plastic-lined steel pipe is an alternative product for industrial pipes in petroleum, chemical, electric power, coal, ships, docks and other industries.
The PO/PP/PE lined pipes can be manufactured as straight pipes, elbows, tees, crosses, and reducers. And other specific dimensions can be supplied on request.
