Leveraging Hydraulic Cyber-Monitoring Data to Support Primitive Condition Assessment of Water Mains
(ASCE, 11/1/2021)Buried water pipelines deteriorate in response to several variables such as pressure transients, corrosion, and pipeline material degradation, among others, that are dynamic processes, and it is therefore difficult to ... -
Improved Design Guidelines for Pipelines Subjected to Vertical Fault Movement in Dry Sand
(ASCE, 11/1/2021)Practicing engineers use the uncertain bilinear soil spring methodology recommended by engineering guidelines to predict soil loads acting on buried pipelines. Even though more advanced solutions are available in the ... -
Finite-Element Analysis of the Influence of Structural Parameters of a New-Type Wedge Ring Gasket on the Contact Pressure of the Main Sealing Surface
(ASCE, 11/1/2021)As a kind of a detachable connection, flange sealing joints are widely used in chemical, nuclear power, and other industries. Research on new gaskets is one of the hotspots of flange connection technology. In this paper, ... -
Statistical Analysis for the Seismic Risk Assessment of Pipelines in India
(ASCE, 11/1/2021)Pipelines are one of the most important lifeline facilities that play a vital role in maintaining the public safety and economic wellbeing of a nation. They traverse over a large area with nonuniform soil conditions and ... -
Modeling Time-Dependent Behavior of Medium-Density Polyethylene Pipes
(ASCE, 11/1/2021)Medium-density polyethylene (MDPE) pipes are widely used for gas transmission and distribution systems. The behavior of the pipes buried in the ground is governed by soil–pipe interaction. MDPE possesses a time-dependent ... -
Numerical Modeling of Buried Steel Pipe Subjected to Impact Load
(ASCE, 11/1/2021)Rockfall is an extremely rapid process involving long travel distances, so the vulnerability of buildings and infrastructure is quite likely. This paper aims to simulate the response of steel buried pipe subjected to impact ... -
Novel Data-Driven Framework for Predicting Residual Strength of Corroded Pipelines
(ASCE, 11/1/2021)For the residual strength prediction of corroded pipelines, the existing standard has a small application range, and the finite-element method has too many assumptions. This paper proposes a new data-driven prediction ... -
Gaussian Fields for Predicting Drift of Oil and Gas Pipes
(ASCE, 11/1/2021)In the oil and gas industry, empirical models are used to estimate the drift of pipes. These models encode pipe geometrical features, measured along the pipe length. If the estimated drift does not meet the operability ... -
Wave Propagation for Axisymmetric Wave Motion in Buried Pipes Conveying Viscous Flowing Fluid
(ASCE, 11/1/2021)This work investigated the wave propagation characteristics of buried pipes conveying viscous flowing fluid under axisymmetric wave motion, where the coupling pipe–soil and pipe–fluid effects are both taken into account. ... -
Analysis of Economic Leakage Level and Infrastructure Leakage Index Indicator by Applying Active Leakage Control
(ASCE, 11/1/2021)Active leakage control (ALC) has an important place in the management and prevention of leaks in water or/and gas distribution systems. However, cost–benefit components and the amount of economically recoverable leakage ... -
Assessing the Fracture Risk of Corroded Cast-Iron Pipes in Expansive Soils
(ASCE, 11/1/2021)It is estimated that 82% of the cast-iron pipe stock in North American water distribution systems have outlived their useful service life. Previous studies have shown that moisture-induced soil expansion is a dominant ... -
Analysis of Water Distribution System under Uncertainty Based on Genetic Algorithm and Trapezoid Fuzzy Membership
(ASCE, 11/1/2021)In most studies of hydraulic simulation of water distribution systems (WDS), the uncertain input parameters such as nodal demands, pipe roughness coefficients, pipe diameters, water levels in reservoirs, and pump characteristics ... -
Optimization of Water Distribution System Operation with Multiple Tanks and Pumps: Application for Asmara, Eritrea’s Water Supply System
(ASCE, 11/1/2021)Pump energy consumption is the major operational cost of water distribution systems (WDS). Defining better pump operation policies can reduce the cost and the enhance service provided. The nonlinear hydraulic behavior of ... -
Small Leak Detection Based on the Combination of Improved Fast Differential Algorithm and Integral Algorithm
