Seamless steel pipe is a kind of long steel with a hollow section and no seams around it.
The steel pipe has a hollow section and is widely used as a pipeline for transporting fluids, such as oil,
Pipes for natural gas, gas, water and some solid materials, etc.
Compared with round steel and other solid steel, steel pipe has the same bending and torsion strength and lighter weight, which is a kind of warp
Economic section steel is widely used in the manufacture of structural and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction.
with
The steel pipe manufacturing ring parts, can improve the material utilization rate, simplify the manufacturing process, save materials and processing hours, such as rolling bearing ring, jack sleeve, etc., has been widely
It is generally made of steel pipes.
Steel pipe or a variety of conventional weapons indispensable material, barrel, barrel, etc. to steel pipe to manufacture.
The steel pipe can be shaped according to the cross-sectional area
Divided into round tube and special-shaped tube.
Since the circular area is the largest under the condition of equal circumference, more fluid can be transported with the circular pipe.
In addition, the ring section is inside the bearing
Or external radial pressure, the force is more uniform, therefore, the vast majority of steel pipe is round pipe.
However, the round tube also has certain limitations, such as in the plane bending conditions, the round tube is not as good as the square, rectangular tube bending strength, some agricultural machinery framework, steel wood home
With such commonly used square, rectangular tube.
According to different uses also need to have other section shape special-shaped steel pipe.
