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.
山东大鼎金属材料有限公司Welded steel pipe is welded by butt weld or spiral weld. In the manufacturing method, it can be divided into low-pressure fluid conveying welded steel pipe, spiral welded steel pipe, direct rolling welded steel pipe, electric welded pipe and other precision steel pipe itself, metal deformation is more uniform, which makes precision steel pipe, part of which, in the process of hardening. For example, when the deformation part is hardened, the deformation will not spread to other non deformed parts. This ensures that the deformation of the pipeline during use will not cause damage or loss.山东大鼎钢管厂27siMn精密钢管的力学性能；抗拉强度屈服强度伸长率截面收缩率冲击吸收能冲击值力学性能试验方法；所有精密钢管都应满足要求。测试机械性能。测试力学性能的方法主要有两种，一种是拉伸试验，另一种是硬度试验。拉伸试验是将精密钢管制成试样，然后在拉伸试验机上拉断试样，然后测量一个或多个力学性能，通常只测量拉伸强度、屈服强度、断裂后伸长率和截面收缩率无缝钢管由优质碳素钢或合金钢制成，分为热轧和冷轧（拉拔）。
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。
