The Difference Between Seamed Steel Rails And Seamless Steel Rails

People who regularly buy steel rails know the difference between seamless steel rails and seamed steel rails.

The so-called seamless steel rails are made from seamless pipes, and the seam steels are machined from seamed pipes.

1. The appearance is different: the seamed steel pipe has welding ribs on the inner wall of the welded pipe, but the seamless steel pipe does not.

2, the pressure is different: the seam steel pipe is about 10 MPa, and the seamless steel pipe pressure is higher.

3. Different uses: The seamed steel pipe is mainly used in the construction industry, while the seamless pipe is mainly used in the machinery industry.

4, the process is different: the seamed steel pipe needs to be welded after rolling, and the seamless steel pipe is formed once in the rolling.
