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。

"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。

在加热时间（s）＝kd，d为工件的厚度，mm，k为系数，和出厂数据。（3）冷却。不同的冷却系统用于不同的组织。它通常在静态空气中冷却。如果工件很大，可以通过吹风或雾来冷却。长度一般为5～8m或4～7m，主要由热轧碳结构和ST65组成。进口规格直径小，305mm，大规格7813mm。7.3。小口径薄壁无缝钢管，如183mm、223 mm、23.93mm等，分别从法国、西班牙进口。

It can be said that, to a certain extent, this is because of excessive interference and other local power from the private interest, the steel industry not only delayed the transfer to the upstream of the industrial chain to achieve the goal, but also made the T overcapacity problem of the steel industry more and more serious. In this regard, the problem of overcapacity in the steel industry has not been alleviated. In essence, it should be a question of the relationship between power and market, whether the market should play a decisive role or not.

太原无缝钢管（集团）有限公司董事长李晓波认为，“带钢”产能属于非法和非法产能，扰乱市场，污染环境，带来隐患。因此，在我国无缝钢管行业从增量发展进入减产阶段时，解决产能过剩问题，禁止“地板钢筋”势在必行。这既是一场“艰苦的战斗”，又是一场“持久战”。

Affected by the financial crisis and economic recession, the United States has frequently used trade remedy measures since 2009. A new study by Chad of trade restrictions imposed globally in 2009, such as countervailing, anti-dumping and special protection, increased by 29.5% compared with 2008. Trade protectionism measures have become an important hidden trouble affecting the world economic recovery.
