In the process of operation, the cold drawn pipe is a kind of high-precision steel pipe material mainly after cold drawing or hot rolling. In use, there will be no oxide layer and cold bending in the inner and outer walls of the cold drawn pipe. It is more powerful and widely used for mouth, high precision, high gloss, flattening and crack-free. It is suitable for automotive and mechanical parts.
The standard configuration of the cold drawn pipe can withstand the advantages of high temperature without leakage and high density. In the process of operation, it is mainly used to produce pneumatic or hydraulic components, such as cylinders or cylinders, which can be seamless pipes. There are also welded pipes. The chemical composition of precision steel pipes includes various organic elements such as carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, and chromium Cr, as well as some special heavy metals and rare metal elements. This guarantees the quality of the product.
Cold-drawn pipes are relatively heavy to some extent relative to some steel pipes. The procedures that will be experienced to a certain extent are also very diverse, but his production process is similar to that of ordinary fine-drawn pipes. Pickling cold rolling procedure.
The cold drawn tube has a large tensile strength, and under the action of external force, it is mainly resistant to plastic deformation and fracture during use. Automobiles, machinery parts, etc., which have high requirements on the accuracy and smoothness of steel pipes. Due to the high precision of the precision brightening tube, the fine tube or round steel is slowly transformed into a precision brightened tube.
Cold drawn pipes attach great importance to the process and process of their products to a certain extent. In the process of production, there will be special technology, and the quality of production is fully qualified. Therefore, the cold drawn tube can achieve relatively durable, wear-resistant, in the production is achieved without fading, non-corrosive, with good stamping and various stability. Cold drawn tubes are usually produced by a series of cold drawing and extraction at very low temperatures. It can be said to be a more durable and better type of steel.www.ht-tube.com
