What is precision seamless tube? What are the characteristics and advantages?

Precision seamless pipe is a kind of high precision steel pipe material after cold drawing or hot rolling. Due to the advantages of no oxide layer on the inner and outer wall, no leakage under high pressure, high precision, high finish, no deformation in cold bending, flaring, flattening and no cracks, precision steel pipe is mainly used for the production of pneumatic or hydraulic components, such as cylinders or oil cylinders, can be seamless pipe, also have welded pipe. The chemical composition of precision steel pipe is carbon C, silicon Si, Manganese Mn, sulfur S, phosphorus P, chromium Cr.

Common materials for precision seamless tubes

The common materials of precision seamless tube are 10#, 20#, 35# and 45#.

The characteristics and advantages of precision seamless tube:

There are many materials that can be produced. As long as steel is not too hard, it can be produced according to needs.
Precision seamless tubes are usually produced by cold rolling process. The specific process is as follows:
Round steel → piercing → pickling → cold rolling → saw head → baling
Seamless tube → pickling → cold rolling → saw head → baling
The characteristics of precision seamless tube:
1, high precision, saving the loss of user quantity in mechanical processing.

2, specifications, a wide range of applications.

3, cold rolled finished products with high precision, good surface quality and good straightness.

4. The inner diameter of steel pipe can be made into hexagonal shape.

5, the steel pipe performance is superior, the metal is relatively dense.

Compared with solid steel, such as round steel, seamless steel tube has the same flexural and torsional strength and light weight. It is a kind of economical cross section steel, widely used in manufacturing structural parts and mechanical parts.
Precision steel tube inherits the advantages of seamless steel tube, but also has its own characteristics. Using precision manufacturing ring parts can improve the material utilization rate, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack covers, etc., have been widely used in precision steel pipe manufacturing.
The popularization and application of precision seamless tube is of great significance to saving steel, improving processing efficiency, reducing processing process or equipment investment, saving cost and processing hours, improving production capacity and material utilization rate, and improving product quality, reducing costs, and improving economic benefits. Generally, the industry with high precision requirements uses precision seamless tube, no precision requirements of most seamless tube, after all, the price of the same specifications of precision seamless tube is higher than that of seamless tube.
