GB/T 9711.1 HSAW Steel Pipe

GB/T 9711.1 HSAW Steel Pipe

Materials
According to GB/T 9711.1 standards, the HSAW steel pipe is made of L175, L210, L245, L290, L320, L360, L390, L415, L450, L485 or L555 steels.

Technical specifications
The maximum outer diameter for the spiral welded pipe is 3048mm.The maximum wall thickness is 30 mm and the maximum length for a single pipe reaches 20,000mm.

Manufacturing Technique
This range of welded steel pipe is manufactured based on helically submerged arc welding technique. During the welding process, the steel is heated by one or more electric arcs between the bare metal's consumable electrodes and the steel plate, thus achieving metallic bonding.

Applications
The GB/T 9711.1 HSAW steel pipe is widely used in transferring combustible gas and non-combustible fluids, including water. It is an ideal substitute for traditional non-alloy steel pipes and alloy steel pipes. We welcome you to choose our spiral pipes for construction of water pipes, natural gas pipelines, and more.
