Study of natural gas pipeline behaviour

[摘要] In order to prevent incidents due to uncontrolled gas leakage and explosion/fires were devastating look at the factors that determine the safety in operation of gas networks made of polyethylene. Sustainability and safety in operation, lines of distribution networks and installations for use in natural gas represents a complex issue with implications for economic, social and environmental. Underground natural gas pipes are subjected to a series of prompts both static and dynamic which could lead to. damage. The complexity of the problems stemming from the diversity of stress factors acting on the related pipelines supply natural gas. In this context, the authors analyse the behaviour of pipelines under the effect of the stresses to which they are subject by using finite element modelling.
