ASSESSMENT OF THE CRITICAL STATE OF THE POLYETHYLENE PIPE IN THE AREA OF THE MECHANICAL METAL-POLYMER JOINT AT LOW CLIMATIC TEMPERATURES
A. S. Struchkov UDC 678.06:621.643 This paper analyzes the distributions of shearing forces arising in the area of the mechanical joint of polyethylene and metal pipes. The value of these forces at low climatic temperatures (down to -60oC) is determined. The results of the theoretical analysis for isothermal conditions permit estimating the working capacity of plastic under different conditions of joints with metal pipes.
