Security of Cross-Country Oil and Gas Pipelines: A Risk-Based Model
(American Society of Civil Engineers, 2016)Pipelines are primarily instrumental for the transportation and distribution of bulk products from one part of a country to another as well as removing finished products from refineries to terminals and depots. Petroleum ... -
Strength Assessment of a Corroded Pipeline through the Burst Test: Case Study
(American Society of Civil Engineers, 2016)Failure due to corrosion has become one of the major problems in maintaining pipeline integrity. Smart -
Optimal Operation of Water Distribution Networks under Water Shortage Considering Water Quality
(American Society of Civil Engineers, 2016)Water shortages are caused by hydrological droughts and by the disruption of the operation of water distribution networks (WDNs). The water pressure and residual chlorine concentration are examples of quantitative and ... -
Field Installation Effect on Steel-Reinforced High-Density Polyethylene Pipes
(American Society of Civil Engineers, 2016)A full-scale field study was conducted in Kansas to investigate the installation effect on steel-reinforced high-density polyethylene (SRHDPE) pipes. Four 2.13 m-long SRHDPE pipes with a diameter of 0.61 m were connected ... -
Mathematical Model of Leakage during Pressure Tests of Oil and Gas Pipelines
(American Society of Civil Engineers, 2015)Leakage may occur during pressure tests of gas pipelines. Locating the position of leakage followed by immediate repair work becomes very important. On the basis of both the theory of natural gas pipeline transportation ... -
Effect of the Number of Broken Wire Wraps on the Structural Performance of PCCP with Full Interaction at the Gasket Joint
(American Society of Civil Engineers, 2016)Broken prestressing wire wraps are the main cause of failure in prestressed concrete cylinder pipes (PCCP). The effect of the number and location of broken wire wraps on the structural performance of PCCP is investigated ... -
Optimizing the Cross-Sectional Area of the Break Pressure Tanks
(American Society of Civil Engineers, 2016)For transporting a large quantity of water over a long distance, large pipes are used. In most cases, water is transported by pumping. Installation of break pressure tanks (BPTs) at proper locations on such pipelines ... -
Three-Dimensional FEM Parametric Analysis of Stiffened Steel Liners in Hydroelectric Pressure Tunnels
(American Society of Civil Engineers, 2016)The availability of tools for safety evaluation of a pressure liner is a relevant issue in both structural and hydraulic engineering. Parametric studies for assessing the stability of stiffened steel liners in hydroelectric ... -
Rotational Characteristics of a Gasketed Bell and Spigot Joint in a Pressurized Reinforced Concrete Pipeline
(American Society of Civil Engineers, 2016)Joints in gravity flow pipelines can be subjected to internal or external pressure, depending on the conditions. Such conditions will influence the rotational stiffness of the joints and therefore may affect the behavior ... -
Impact of Model Errors of Burst Capacity Models on the Reliability Evaluation of Corroding Pipelines
(American Society of Civil Engineers, 2016)This paper quantifies the impact of model error associated with the burst capacity model on the probability of burst of corroding oil and gas pipelines due to the internal pressure. Three burst pressure models that are ... -
Evaluation and Application of the Flexural Rigidity of a Reinforced Concrete Pipe
(American Society of Civil Engineers, 2016)Design of reinforced concrete pipes focuses on circumferential bending moment. Analytical or numerical methods can be used to estimate these, but an adequate representation of the soil conditions and pipe properties is ... -
Uplift Resistance of Interfering Pipelines Buried in Sand
(American Society of Civil Engineers, 2016)The vertical uplift resistance of interfering pipelines buried in sands has been computed using the lower-bound limit analysis in conjunction with finite elements and nonlinear optimization. The soil mass is assumed to ... -
Using the Unit Force Method to Analyze Thrust Acting on Anchor Blocks Caused by Thermal Expansion Displacement of X80 Tunnel Pipelines
(American Society of Civil Engineers, 2016)To restrict the thermal expansion displacement of X80 tunnel pipelines, anchor blocks are commonly designed and installed at entrances and exits of tunnels, which makes the anchor block design one of the most important ... -
Field Inspection of Corrugated HDPE Pipeline Network under Heap Piles at a Copper Mine Site in Chile
(American Society of Civil Engineers, 2016)In-service conditions of a corrugated high density polyethylene (HDPE) pipeline network embedded within a bioleaching pad in the Atacama Desert in Chile were assessed. The pipes provided air for the copper extraction process ... -
