Abstract
The fact of increasing the elasticity of polyethylene gas pipelines in the process of long-term aging has been found. resumably, the increase in elasticity is due to the accumulation of mercaptans present in natural gas in the wall of the polyethylene pipe. It is shown that a specific mechanism for increasing elasticity during long-term operation consists in creating conditions for the development of secondary necking.
