The purpose and significance of precision seamless steel pipes

First, what are precision seamless steel pipes?
Precision seamless steel pipes are a kind of high-precision steel pipe material that has been processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipes have no oxide layer, can withstand high pressure without leakage, high precision, high finish, cold bending without deformation, expansion, flattening without cracks, etc., they are mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders. They can be seamless steel pipes or welded pipes. The chemical composition of precision steel pipes includes C, Si, Mn, S, P, and Cr. Compared with solid steels such as round steel, seamless steel pipes are lighter in weight when the bending and torsional strengths are the same. They are economical cross-section steel and are widely used in the manufacture of structural parts and mechanical parts.

Compared with solid steels such as round steel, seamless steel pipes are lighter in weight when the bending and torsional strengths are the same. They are economical cross-section steel and are widely used in the manufacture of structural parts and mechanical parts. While inheriting the advantages of seamless steel pipes, precision steel pipes also have some of their own characteristics. Precision manufacturing of annular parts can improve material utilization, simplify manufacturing processes, and save materials and processing time. For example, rolling bearing rings, jack sleeves, etc. have been widely manufactured with precision steel pipes. The promotion and application of precision seamless steel pipes are of great significance to saving steel, improving processing efficiency, reducing processing procedures or equipment investment, saving costs and processing time, increasing production and material utilization, and at the same time helping to improve product quality and reduce costs, which is of great significance to improving economic benefits. Generally, industries with high precision requirements use precision seamless steel pipes, and those without precision requirements mostly use seamless steel pipes. After all, the price of precision seamless steel pipes of the same specifications is higher than that of seamless steel pipes.

Second, the characteristics of precision seamless steel pipes
1. High precision, saving the loss of mechanical processing users’ labor and materials.
2. Many specifications and a wide range of applications.
3. The cold-rolled finished product has high precision, good surface quality, and good straightness.
4. The inner diameter of the steel pipe can be made into a hexagon.
5. The performance of the steel pipe is superior and the metal is denser.

Third, what are the uses of precision steel pipes? It is widely used in steel pipes for hydraulic systems, steel pipes for injection molding machines, steel pipes for hydraulic machines, steel pipes for shipbuilding, EVA foaming hydraulic machinery, steel pipes for precision hydraulic cutting machines, shoemaking machinery, hydraulic equipment, high-pressure oil pipes, hydraulic oil pipes, ferrule joints, steel pipe joints, rubber machinery, forging machinery, die-casting machinery, engineering machinery, high-pressure steel pipes for concrete pump trucks, sanitation vehicles, automobile industry, shipbuilding industry, metal processing, military industry, diesel engines, internal combustion engines, air compressors, construction machinery, agricultural and forestry machinery, etc., and can completely replace imported seamless steel pipes of the same standard.
