Through continuous improvement of service competitiveness, won the praise of the market. Song style; precision steel pipe is a high precision steel tube material after cold drawing or hot rolling. Precision steel pipes are mainly used for the production of pneumatic or hydraulic components, such as cylinders or cylinder products, they can be seamless or welded, but most of them are precision seamless steel. Precision pipe has the advantages of high outer surface of pipe after heat treatment, no flattening crack, cold bending deformation, high pressure resistance, and various complex deformation and mechanical processing. Deep processing. It mainly produces steel pipe grades 10, 20, 35 and so on. Precision steel pipe;
山东大鼎钢管厂A set of equipment can be used for pipeline insulation: steel pipe shot peening and rust removal, ternary PE winding equipment, SIMN seamless PE pipe black and yellow jacket pulling machine, sand blasting and rust removal equipment, polyurethane low-pressure tendering, foaming platform, GL donkey fiber reinforced plastic winding machine, two-layer PE coating, cement mortar spraying machine and other anti-corrosion and insulation test equipment. In the tensile test, the ratio of the large reduction of the cross-section area to the original cross-section area when the specimen shrinks is called the cross-section shrinkage.

In addition, the company sells a variety of seamless steel pipe, alloy pipe welded pipe Chengdu Iron and Steel Group production, smelting iron and steel group, Baotou Iron and Steel Plant, Baosteel Group,and so on. Perhaps the fluid pipes used in previous transportation are seamless steel pipes. . However, with the continuous development of science and technology, technology and innovation research and development, welded pipe is now a very good development. Compared with seamless pipe, the thickness of the steel pipe wall is more uniform, and the accuracy is much better than that of seamless pipe. Now, in the United States or some developed countries in Europe, many seamless steel tubes are replaced by welded pipes.
