山东大鼎金属材料有限公司The main characteristics of precision seamless steel pipe in precision steel pipe mill are: high precision, high inner and outer wall finish, no oxide layer after heat treatment, high inner wall cleanliness, high pressure bearing, cold bending deformation, flattening, no crack. It can be used for all kinds of complex deformation and machining. Steel tube color: bright white medium, high metallic luster. Precision seamless steel pipe process: high quality carbon steel, finish rolling, non-oxidizing bright heat treatment state, non-destructive testing, steel pipe inner wall with special equipment cleaning, high pressure flushing, rust-proof oil coated on the steel pipe, used for rust prevention. When installing, two end covers are used for dust prevention.山东大鼎钢管厂石油裂化用无缝钢管（GB9948-88）是适用于石油精炼厂的炉管、热交换器和管道无缝钢管。7.地质钻探用钢管（YB235-70）是供地质部门进行岩心钻探使用的钢管。8.金刚石岩芯钻探用无缝钢管（GB3423-82）是用于金刚石岩芯钻探的钻杆、岩心杆、套管的无缝钢管。
精密钢管由于具有内外壁无氧化层、高压无泄漏、精度高、精度高等优点，主要用于生产气动或液压元件，如气缸或气缸等无缝或焊接产品。SH，没有冷弯变形，平整和无裂纹。精密钢管主要生产10、20、35、45、40cr、42CrMo级钢管等精密无缝钢管也可咨询供应。Through continuous improvement of service competitiveness, won the praise of the market. 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.
