Abstract:

Factors influencing the performance of underground gas pipes are identified through a literature search and contacts with several utility companies. These factors are categorized as (i), those related to soil, (ii) factors related to pipe itself and, (iii) other factors related to the environment or man made facilities. In the second part of the paper, the role of the influencing factors and the uncertainties in them in the failure of underground gas pipes have been investigated. The failure probability of an underground gas pipe under the effect of three influential factors is investigated and calculated.
