"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。

Oil quenching causes surface deterioration easily. Due to the high surface activity, significant thin layer carburization can occur under the action of short and high temperature oil film. In addition, the adhesion of carbon black and oil on the surface is not conducive to simplifying the heat treatment process. The development of vacuum quenching technology mainly lies in the development of single gas cooled quenching furnace with excellent performance. Double chamber furnace can also be used for gas quenching (front chamber air jet cooling), but the operation of the two stations makes it difficult to load a large number of furnace, and easy to cause workpiece deformation or change the direction of workpiece quenching. NG deformation during high temperature movement.
山东大鼎钢管厂公式计算钢管的理论重量：W=(D-S)＊S＊0.02466，其中W=钢管每米的重量；S=钢管的公称壁厚；D=钢管的公称外径，光亮管的表面质量i清洁、无氧化层、无裂纹、折叠、轧制、结疤、分离层和条纹。
