What is the difference between seamless steel pipe and seamless steel pipe?

There are four differences between seamless steel pipe and seamless steel pipe:

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

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

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

4. Different processes: seamless steel pipes need to be rolled and welded, while seamless steel pipes are formed in one step during rolling.

Steel pipes are not only used for conveying fluids and powdered solids, exchanging heat energy, making machine parts and containers, but also an economical steel. Steel pipes can be used to make building structural grids, columns and mechanical supports, which can be reduced.

Light weight, saving 20~40% of metal, realizing industrialized mechanized construction. Using steel pipes to manufacture highway bridges can not only save steel and simplify construction, but also greatly reduce the area of ​​protective coatings, saving investment and maintenance costs.

There is another situation.

Two types of steel pipes are two types.

Galvanizing refers to the surface galvanizing of steel pipes, which can be welded pipes or seamless steel pipes.

Seamless refers to the manufacturing process of steel pipes, which is divided into welding and seamless.

Seamless steel pipes are stamped into capillaries from steel ingots or solid billets, and then hot rolled, cold rolled or cold drawn. They have a hollow cross-section and are widely used as pipes for transporting fluids. Compared to solid steel such as round steel, steel pipes are lighter in weight when the bending and torsional strengths are the same. They are economical steels and are widely used in the manufacture of structural and mechanical parts such as oil drill pipes, automobile drive shafts, bicycle frames and steel scaffolding for construction.

There are two types of galvanized steel pipes: hot-dip galvanized and electro-galvanized. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance is very different from that of hot-dip galvanized pipes.

Seamless steel pipes are stamped into capillaries from steel ingots or solid billets, and then hot rolled, cold rolled or cold drawn. Seamless steel pipes have hollow sections and are widely used as pipes for transporting fluids. Welded pipe refers to a steel pipe with a welded surface formed by bending a steel strip or steel plate into a circular shape and then welding. The blanks used for welded pipes are steel sheets or strips. .
