Precision steel pipe is mainly used to produce pneumatic or hydraulic components because of its advantages such as no oxide layer on the inner and outer walls, high pressure, no leakage, high precision, high finish, no deformation in cold bending, flatness and no cracks. As a cylinder or an oil cylinder, it can be a seamless tube. The chemical composition of cold drawn precision steel pipe is carbon, silicon, Si, manganese, sulfur, phosphorus, phosphorus and Cr.. The popularization and application The so-called high-precision cold-drawn pipe is characterized by strict internal and external diameter accuracy (tolerance range), good surface finish, good roundness, uniform wall thickness. Some or exceed the requirements of standard GB and standard ISO434/i-1980
2011年10月，美国应美国钢铁公司和美国钢铁工人联合会的请求，提交了反补贴案。当时，中国官员说，他们盲目地指责从中国进口产品倾销或补贴，缺乏事实依据，中国坚决反对这种做法。
对于高碳钢，正火可以重组渗碳体，促进球化。对于截面变化剧烈的大型精密钢管或铸钢件，可以采用正火代替淬火，也可以采用变形和开裂倾向，或者可以制备淬火组织。精密钢管的淬火、修复部分会受到正火和过热的影响，从而发生再硬化。

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。
山东大鼎钢管厂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。加强对精密钢管焊工基本技能的培训无缝精密钢管价格，根部不熔合缺陷；注意层间修整，避免槽带不当导致不熔合；严格按照要求，合理使用。山东大鼎金属材料有限公司Adjust the current and correctly handle the grinding angle and welding retention time of tungsten wire. Precision steel pipe has the characteristics of high dimensional accuracy, high surface finish, no oxide film on the inner and outer surface of the pipe after heat treatment, flat and crack-free pipe, cold bending deformation, high pressure resistance, etc. It can be used for various complex deformation and mechanical processing. CAL deep processing. The difference is that the main feature of seamless steel pipe is no welded joints, which can withstand greater pressure. The products can be rough castings or cold parts.
