Erw Line Pipe
Erw Line Pipe is a type of steel pipe that is used for transporting oil, gas, water and other fluids across long distances. Erw stands for electric resistance welded, which means that the pipe is made by joining the edges of a steel strip with an electric current. It has many advantages over other types of pipes, such as seamless or spiral welded pipes, and it is widely used in various industries and projects.

Product Highlights
- High production efficiency and a low cost, as it can be manufactured in large quantities and in different sizes and grades.
- Good performance and a long service life, as it can withstand high pressure, corrosion, temperature and mechanical stress.
- Uniform and smooth surface and a consistent wall thickness, which ensures a good flow and reduces friction loss and energy consumption.
- Be easily welded, cut, bent and shaped, which provides flexibility and convenience for installation and maintenance.
- Be coated with various materials, such as zinc, epoxy, polyethylene, etc., to enhance its protection and appearance.
