The ability of metal materials to resist indentation of hard objects has a small circumference/area ratio on all geometric sections, i.e., large internal sections can be obtained with the same number of materials. Because of its low cost and high strength, steel pipe has been widely used in modern fluid transportation. According to the different production process, the steel pipe is divided into seamless steel pipe and welded steel pipe, they are divided into high frequency longitudinal welded pipe (ERW), spiral welded pipe (SSAW), submerged arc welded pipe (UOE) and so on. In the past, traditional seamless pipes were used for fluid pipelines.山东大鼎钢管厂

精密钢管是冷拔或热轧后的一种高精度钢管材料。精密钢管主要用于生产气动或液压元件，如气缸或气缸的产品，它们可以是无缝的或焊接的，但大多数是精密无缝钢。管。精密钢管具有尺寸精度高、表面光洁度高、热处理后管内外表面无氧化膜、管材无压扁裂纹、冷弯变形、耐高压、能进行各种复杂变形和机械加工等优点。深加工。主要生产钢管牌号：10, 20, 35、45、40Cr、42CRMO等。精密钢管；GB/T699—2008；GB/T3639－2008。

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.
