Development of technology of manufacturing pipes with an inner diameter of 6-12 mm

The article presents the results of the research work aimed at developing the technology of manufacturing pipes with an inner diameter of 6-12 mm at JSC “Sinarsky Pipe Plant” (Kamensk-Uralsky). To test the proposed technology a number of experimental and practical works have been performed. It was shown that the most effective is the technology of using a free floating-plug drawing method. Based on the results of the mathematical modeling, main parameters of the free floating-plug drawing method were analyzed, such as rational profiles of technological tools and deformation regimes. Estimation of the efficiency of technological lubricants was carried out and recommendations for the equipment selection were presented. Technical and economic estimation of the proposed solutions showed that the most effective process of manufacturing pipes of this assortment is bull-block drawing. Proposals for the organization of the shop of bull-block drawing pipes at JSC “Sinarsky Pipe Plant” were developed. Technical solutions were proposed as intellectual property objects.
