Advantages of cold drawn Seamless Steel Pipe

Precision seamless pipe is a kind of high-precision steel pipe material processed by cold drawing or hot rolling. Because the inner and outer walls of precision steel pipe have no oxide layer, withstand high pressure without leakage, high precision, high finish, no deformation in cold bending, expansion There are some points, such as flattening and no cracks, so it is mainly used to produce pneumatic or hydraulic components, such as cylinders or oil cylinders, which can be seamless pipes or welded pipes. The chemical composition of precision steel pipes is carbon C, silicon Si, manganese Mn , sulfur S, phosphorus P, chromium Cr, compared with solid steel such as Round Steel, seamless steel pipes are lighter in weight when they have the same flexural and torsional strength, and are an economical section steel, widely used in the manufacture of structural parts and machinery Component.

Cold drawn precision seamless tube

Cold-drawn precision seamless steel pipe is a precision cold-drawn seamless pipe with high dimensional accuracy and good surface finish for mechanical structures and hydraulic equipment. The use of precision seamless pipes to manufacture mechanical structures or hydraulic equipment can greatly save machining hours, improve material utilization, and help improve product quality.

If you want to obtain a small-diameter seamless steel pipe with a smaller size and better quality, you must use cold rolling, cold drawing or a combination of the two. Cold rolling is usually carried out on a two-roll mill, and the steel pipe is rolled in an annular pass formed by a circular hole groove with variable cross-section and a stationary tapered plug. Cold drawing is usually carried out on a 0.5-100T single-chain or double-chain cold drawing machine.
