The production and use of natural gas in China is growing quickly, and the same applies to the natural gas industry. Nowadays, several regions are crossed by natural gas pipeline networks. This document introduces the main gas transportation systems in this Country. Furthermore, it analyses the causes of the main gas pipeline incidents occurred in recent years in China, United States and Europe, as well as the most popular monitoring and failure prevention methods. Finally, the detrimental effects on safety due to the stress concentration induced by the possible presence of defects on the pipe wall is analyzed by the finite element method.
La produzione e l’uso di gas naturale in Cina stanno crescendo rapidamente, e contemporaneamente cresce il relativo comparto industriale. Attualmente, sono numerose le regioni cinesi attraversate da condotte per il trasporto di gas naturale. Questa tesina introduce le principali reti di trasmissione di questo Paese ed analizza le cause e i metodi di monitoraggio e prevenzione degli incidenti in Cina, ma anche negli Stati Uniti e in Europa. Infine, si utilizza il metodo degli elementi finiti per verificare l’incidenza sui limiti di sicurezza della concentrazione degli sforzi che si realizza in corrispondenza di possibili difetti presenti sulla superficie delle tubazioni.

Abstract
The production and use of natural gas in China is growing quickly, and the same applies to the natural gas industry. Nowadays, several regions are crossed by natural gas pipeline networks. This document introduces the main gas transportation systems in this Country. Furthermore, it analyses the causes of the main gas pipeline incidents occurred in recent years in China, United States and Europe, as well as the most popular monitoring and failure prevention methods. Finally, the detrimental effects on safety due to the stress concentration induced by the possible presence of defects on the pipe wall is analyzed by the finite element method.File | Dimensione | Formato | |
