三辊行星轧机(PSW)、顶管机和连轧管机三种钢管生产方法的几个重要方面的比较。 1.总论三辊行星轧管工艺可以以它的产量和尺寸范围与顶管机和连轧管机竞争。通过这三种生产方法的比较,可以清楚地说明PSW在技术和经济上的优点。在与PSW方法作比较的时候,顶管机和连轧管机这两种传统工艺的不同之处并不重要,因此没有必要单独考虑。
Three Roller Planetary Mill (PSW), pipe jacking machine and pipe mill three kinds of pipe production methods of several important aspects of the comparison. 1. General The three-roll Planetary Tube Rolling process can compete with pipe jacking and rolling mills in terms of its production and size range. The comparison of these three production methods clearly shows the technical and economic advantages of PSW. When compared with the PSW method, the difference between the two conventional processes, pipe jacking and tube rolling, is not important, so there is no need to consider it separately.
