摘要：
The results of testing the existing restrictions on bending of polyethylene pipes at different temperatures are presented. According to the mathematical model using the dependences of the elastic modulus and yield point, the stresses arising in the walls of pipes of different diameters during bending at different temperatures were calculated. The obtained dependences assume that if the design of the guide unit of the plow-type pipe-layer will provide the above conditions, the stresses arising in the pipe will not exceed the yield point, that is, the required installation conditions will be met.
