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。



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)。
