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.
