What's the difference between seamless steel pipe and slotted steel pipe?

There are four differences between seamless steel pipes and seamless steel pipes, as follows:

1. The appearance is different: welded steel pipes with seams have welding ribs on the inner wall of welded pipes, but seamless steel pipes do not.

2. Different pressures: The pressure of seamless steel pipe is higher than that of seamless steel pipe, about 10 MPa.

3. Different uses: Seamless steel pipes are mainly used in the construction industry, while seamless steel pipes are mainly used in the machinery industry.

4. Different processes: welded steel pipes need to be rolled and welded, while seamless steel pipes are rolled and formed at one time.

Extended data

Steel pipe is not only used for conveying fluids and powdery solids, exchanging heat energy and manufacturing mechanical parts and containers, but also an economical steel. It can reduce the use of steel pipes to manufacture grids, pillars and mechanical supports of building structures.

Light weight, saving 20-40% of metal, and realizing the mechanized construction of the factory. Using steel pipes to make highway bridges can not only save steel and simplify construction, but also greatly reduce the area coated with protective layers and save investment and maintenance costs.
