Pipelines in general therefore represent a small risk to Pipelines in general therefore represent a small risk to human life and to the environment. However, pipelines represent large capital cost, and any pipeline failure has significant economic impact because of the cost of repair and the loss of transportation capacity. Introduction. Service failures and safety incidents of machines, structures, and pressure equipment have been experienced in the oil and gas industry for many years without warning, with varying degrees of consequential damages to health, safety, environmental, business, and reputation. $,$, per mile, depending on the size of the pipeline.9 In spite of these high upfront costs, there are currently o miles of pipeline either under construction or planned in North America This suggests that, despite their high upfront costs, pipelines are considered a worthwhile investment. In this study, the effect of the friction factor on the pressure drop calculations for gas flow is presented. Various correlations for friction factors are utilized to demonstrate their impact on the design of natural gas pipelines. Also, a summary and a comparison of results are presented for different flow rates, pipe sizes, and for field by: 3.

Abstract - This research work on the analysis of oil pipeline failures in oil and gas industries in the Niger delta area of Nigeria was carried out to ascertain the causes of these failures. Information on pipeline conditions was gathered for the period between and Observations showed that the major. Normally the pipelines carry high sulphur fuel oil (HSFO), low sulphur fuel oil (LSFO), or gas oil. • The total sulphur by weight is 4% max in HSFO, 1% max in LSFO and 1% max in gas oil. • Small amounts of water are regularly drained from station tank bottoms. H 2 S is not apparent in tanks. • Occasionally crude oil has been carried.

Reading this book on Oil and Gas Pipeline Fundamentals has been quite educational. In reviewing the aspects of Oil and Gas Pipeline issues currently being talked about it is good to know what the pipelines are all about. This is the basis of what can be a challenging debate.4/5(3).

Predicting corrosion in pipelines, oil wells.   AbstractThe internal corrosion of pipelines in the petroleum industry is highly risky, and induced pipeline cracking may give rise to potential injury to personnel and environmental issues. The oil-water two-phase flow and the oil-gas-water three-phase flow are often observed in gathering and transportation pipelines. It is generally accepted that corrosion is induced by the presence of water Cited by: 2.
