Abstract. In recent years, polyethylene pipes are used more and more often in the gas industry. In the construction of pipeline, especially for trenchless laying and repairing, they are subject to considerable bending stresses. The magnitude of the stress in the pipe wall can briefly approach the yield point. The article is devoted to the study of mechanical characteristics of polyethylene pipes at short bending. The results can be used for engineering calculations at trenchless laying and repairing of pipelines.
