Seamless Steel Pipe for Liquid Transport

Description

Seamless steel pipe for liquid transport is a long hollow tube used for transporting fluids and protecting electrical or optical cables and wires. There is no welding line in the whole tube. This product is largely used for transporting petroleum, natural gas, coal gas, water and some solid materials. Compared with round steel and other solid steels, this seamless steel tube is more lightweight. Seamless steel pipe for liquid transport is also an economical steel material used for manufacturing structural components and machine parts, such as oil drill pipe, transmission shaft of motor vehicle, bicycle frame and steel scaffold.

Advantages

1. Seamless steel pipe for liquid transport can be used as boiler tube at below 450℃.
2. This product has high strength, good anti-corrosion property, and structure stability.
3. This seamless steel tube meets the national standard of GB/T8163.
