"In order to seize the opportunity of the reform of state-owned enterprises, the reform of the public service sector can be tried first, relying on employees to realize the vision of development." In December 2014, the chairman of Xu Lejiang Company, Secretary of the Party Committee, put forward requirements and expectations for the branch of steel pipe and strip, and pointed out the direction of "winter training" for the branch. Steel pipe workers are moving. From 2015 onwards, the Ministry of Railways has been exploring and practicing on deepening reform by changing its concept and overcoming bottlenecks. In reform, 山东大鼎钢管厂、山东大鼎金属材料有限公司精密无缝钢管是采用冷拔或冷轧工艺生产的高精度、高亮度的无缝钢管。内外径可细化1～0.1mm，弯曲强度和扭转强度相同时，重量轻。精密无缝钢管用于精密机械结构、轴承液压、机械加工、液压设备、钢套管。广泛用于汽车、摩托车、电动汽车、石化、电力、船舶、航天、轴承、气动元件、中低压锅炉无缝钢管。

Some distributors seize this point and work with downstream end users to inform seamless steel mills of their respective requirements for precision steel pipes and then send the products directly to end users for use. This method is helpful for dealers to firmly grasp the needs of the downstream end-users. It can not only transport precision steel pipes from the precision steel pipe mill to the downstream end-users, but also ensure that the end-users can use seamless steel pipe products more quickly. In this way, the efficiency of the precision steel pipe is improved,of pure trade has become increasingly limited, to expand the precision steel pipe processing business, so that they can not be replaced in order to survive.液压和气动缸筒用精密内径无缝钢管（GB8713-88）是制造液压和气动缸筒用的具有精密内径尺寸的冷拔或冷轧精密无缝钢管。供暖采用聚氨酯保温管那是一种趋势 直埋式外压波纹补偿外壳及导向套筒保护下实现自由伸缩补偿冷拔或冷轧精密无缝钢管（GB3639-83）是用于机械结构、液压设备的尺寸精度高和表面光洁度好的冷拔或冷轧精密无缝钢管。选用精密无缝钢管制造机械结构或液压设备等，可以大大节约机械加工工时，提高材料利用率，同时有利于提高产品质量。精密钢管的种类很多。许多精密钢管需要在下游用户使用之前进行加工。
