"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。

Domestic pipes are mainly made up of hot rolled or cold drawn and root carbon welded pipes. Precision tubes are usually used under high temperature and high pressure conditions. When pipes are used as boiler tubes for high temperature flue gas and steam, they will be oxidized and corroded. The steel pipe is required to have high durability, high oxidation resistance, corrosion resistance and good microstructure stability. According to the high temperature performance of boiler tubes, the boiler tubes are divided into common boiler tubes and high-pressure boiler tubes. General boiler tubes or high pressure boiler tubes can be divided into various types of pipes according to their needs.高压锅炉用无缝钢管（GB5310-2008）是用于制造高压及其以上压力的水管锅炉受热面用的优质碳素钢、合金钢和不锈耐热钢无缝钢管。5.化肥设备用高压无缝钢管（GB6479-2000）是适用于工作温度为-40~400℃、工作压力为10~30Ma的化工设备和管道的优质碳素结构钢和合金钢无缝钢管。精密管制造方法一般精密管在350℃以下使用。
The vacuum carburizing temperature is generally higher than that of ordinary gas carburizing. Carburizing and diffusion are often used at 920~1040 C. As shown, there are two stages: pulse ventilation, stop gas, multi-stage carburizing and diffusion. The effect is better. Vacuum carburized layer is formed faster than ordinary gas, liquid and solid carburized layer because of its high temperature, especially its clean surface and high activity. If the carburized layer needs 1 millimeters, it will take 927 hours and 1 hours at 1033 degrees Celsius, only 5 hours.
Precision steel pipe has the advantages of no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, small cold bending deformation, high flatness, no cracks and so on. It is mainly used to produce pneumatic or hydraulic components. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe
