The popularization and application of high-precision pipes saves steel, improves processing efficiency and saves energy. The so-called high-precision cold-drawn pipe refers to the internal and external diameter precision (tolerance range) is strict, good surface finish, good roundness, uniform wall thickness of cold-drawn pipe. The main technical indexes of the high precision cold drawn tube produced by this technology reach the expected goal. Details are shown in the following table: the main technical indicators and the standard control table items have actually reached the GB8713-88 ISO4394 internal diameter tolerance H8 H9 H8 H8 H8 H8 H8 H8 H8 H8 H9 H9 H10 straightness 0.3 > 0.5/1000B wall thickness deviation roundness汽车半轴套管用无缝钢管（GB3088-82）是制造汽车半轴套管及驱动桥桥壳轴管用的优质碳素结构钢和合金结构钢热轧无缝钢管。德威花园城一期占地约 这是它的柴油机用高压油管（GB3093-86）是制造柴油机喷射系统高压管用的冷拔无缝钢管。精密管或冷轧精密无缝管(GB3639-2000)是机械结构和液压设备用尺寸精度高、表面光洁度好的冷拔或冷轧精密无缝管。高精度精密管是一种新型的高技术节能产品。
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。
Precision steel pipes are mainly used to produce seamless or welded products such as pneumatic or hydraulic components, such as cylinders or cylinders, because of their advantages such as no oxide layer on the inner and outer walls, high pressure, no leakage, high precision and so on. SH, no cold bending deformation, flat and no crack. Precision steel pipe mainly produces 10, 20, 35, 45, 40 cr, 42CrMo grade precision seamless steel pipe can also be consulted and supplied.
At heating time (s) = KD, D is the thickness of the workpiece, mm, K as the coefficient, and the factory data. (3) cooling. Different cooling systems are used for different tissues. It is usually cooled in static air. If the workpiece is large, it can be cooled by blowing or fog. The length is usually也许正是因为这个原因，在过去相当长的时间，另一方面，虽然有关各方已提出了许多警告，产能过剩的钢铁行业，甚至进行产业结构调整，地方政府仍然回避了铁和ST通过“变为零”等政策的对策就是鳗鱼项目；同时，为了维护相关的钢铁产能对地方GDP的贡献，有些地方还不遗余力地支持当地落后产能项目日即使他们清楚地知道一些地方钢铁项目的产量明显落后，政策倾斜。
