石油、地质用管在使用过程中最容易损坏的地方是其丝扣连接部分。为了提高丝扣连接强度,钢管端部须进行加厚。钢管端部加厚所采用的加厚设备有平锻机和卧式水压机两种。这两种加厚机的工作性质和管端加厚的变形状态都完全一样,仅机械结构和作用原理有所不同。 Oil, geological pipe in the process of using the most vulnerable areas of its threaded connections. In order to improve the threaded connection strength, the pipe ends must be thickened. Thickened pipe end thickened equipment used for flat forging machine and horizontal hydraulic machine two. The working properties of these two kinds of thickening machines are the same as those of the thickened end of the pipe, and only the mechanical structure and the principle of action are different.
