With plastic pipes with increased axial and radial sustainable domestic plastic pipes

摘要

With plastic tube with enhanced axial and radial stability of inner plastic tube, it relates to protect steel pipes from corrosion during transportation of corrosive media. With plastic tube with enhanced axial and radial stability of inner plastic tube, comprising an outer steel pipe, the inner plastic tube, where new is that the overall length of the plastic tube is separated into portions of reduced length by setting the nozzle, thus achieving the increase in axial and radial stability of the plastic tube in during operation of the pipeline. At the same time, the conditions for increasing the temperature of the transported medium. 1- Fig. 4 ZP f-ly.
