摘要

发现了聚乙烯输气管道在长期老化过程中弹性增大的事实。同样，弹性的增加是由于天然气中硫醇在聚乙烯管壁中的积累。结果表明，在长期运行过程中增加弹性的具体机制在于为二次颈缩的发展创造条件。

Investigation of the growth of elasticity in gas polyethylene pipes during long-term aging

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.
