Precision seamless steel pipe

Precision seamless steel pipeis a kind of steel pipe which after cold drawn or hot rolling process . Because of the precision steel tube inside and outside wall without oxidation layer, under high pressure without leakage, high precision, high finish, cold bending deformation, flaring, flattening without cracks a bit, it is mainly used to produce pneumatic or hydraulic components products, such as a cylinder or cylinder, can be a seamless steel pipe, welded pipe. The chemical composition of precision steel tube with carbon sulfur C, Si, Si, Mn, Mn, S, P, P, chromium Cr.

Precision seamless tube usually takes the process of cold rolling production. Specific process is as follows:

Round steel to punch to pickling, cold rolling, he saw the head - banding

The seamless pipe to pickling, cold rolling - saw the head - banding

Precision seamless tube characteristics and advantages

The characteristics of precision seamless tube

1, high precision, saves machining user quantity at the time of the loss.

More than 2, specifications, wide range of applications.

3, cold-rolled products high accuracy, good surface quality, straightness is good.

4, steel pipe diameter can make hexagonal.

5, steel pipe is superior performance, more dense metal.

Seamless steel pipe and round steel, compared to solid steel in the bending torsional strength phase at the same time, the weight is lighter, is a kind of economic cross section steel, widely used in the manufacture of structural and mechanical parts. Precision steel tube in inherits the advantages of seamless steel tube at the same time, also has some characteristics of its own. Made circular parts with precision and can improve the material utilization, simplifying the manufacturing process, material saving and processing time, such as rolling bearing ring, jack sets, etc., has been widely used to manufacture precision steel pipe. Application of precision seamless tube to save steel, improve the machining efficiency and reduce the processing process or equipment investment is important, can save cost and processing time, increase production and material utilization, at the same time to improve product quality, reduce costs, to improve the economic benefit is important. Generally used for high precision demand industry precision seamless tube, mostly with which do not require precision seamless tube, after all the same specifications precision seamless pipe price is higher than that of seamless tube.
