ERW Steel Pipes

Features
The use of the mild steel, which is easy to weld, ensures the high-quality appearance of the ERW steel pipe. During the forming process, the steel plates are uniformly deformed with little residual stress and less vulnerability to scratching. Thisprocess can customize steel pipes for the clients with regard to the diameter and wall thickness. We have incomparable advantages in producing high strength, thick-walled steel pipes and medium and small thick-walled steel pipes.

Applications
The ERW steel pipe is regularly used for long distance transferring of water, petroleum, natural gas, coal gas and pulp, etc. Our ERW steel pipes can also be used in the chemical and electricity industries.

Maintenance
The ERW steel pipe needs to be protected during the transportation, loading and uploading processes. Painting the surface and using a protector are also necessary.
