Semianalytical Solution for Buried Pipeline Subjected to Horizontal Transverse Ground Deformation
(ASCE, 11/1/2021)For buried pipelines, it is not always possible to avoid active zones where there is a possibility of ground deformation either due to earthquake or topographical reasons, and hence it is necessary to understand the impact ... -
Experimental Study of Flow Characteristics in Vortex Drop Shaft
(ASCE, 8/1/2021)Vortex drop shafts are utilized to dissipate and transport the energy of flows in sewerage networks. A vortex drop shaft is composed of three parts: the inlet structure, the vertical shaft, and the dissipation chamber. ... -
Assessment of Interaction Between a Dent and an Adjacent Corrosion Feature on Pipelines and the Effect on Pipeline Failure Pressure by Finite-Element Modeling
(ASCE, 8/1/2021)Dents and corrosion are two types of defects commonly found on pipelines. Although major efforts have been made to assess the defects of each type, there is a limited understanding of interaction between the two defects ... -
Comparison Case Study of Risk Assessment of Dropped Objects on Subsea Pipelines
(ASCE, 8/1/2021)Det Norske Veritas is a company that gives an available classification guidance, which can provide a systematic methodology to estimate the risk due to dropped objects for the purpose of subsea pipeline projection. Firstly, ... -
Blockage Detection in Gas Pipelines to Prevent Failure of Transmission Line
(ASCE, 8/1/2021)Gas pipelines are an integral part of each stage across several industries, including steel, oil, chemical, and pharmaceutics. Deposit of sediments causes blockages in pipelines, which leads to abrupt failure and functional ... -
Experimental Study on Uplift Mechanisms of Pipes Buried in Sloping Medium Dense Sand
(ASCE, 8/1/2021)Experiments are conducted to study the uplift behavior of buried pipes in medium dense sand with ground slopings of 0°, 10°, 20°, and varying burial depths. Test results show that the peak uplift resistance reduces with ... -
Lateral and Uplift Capacity of Pipeline Buried in Seabed of Homogeneous Clay
(ASCE, 8/1/2021)Buried offshore pipes are prone to upheaval and lateral buckling because of the high temperature and pressure of the materials being transported. An attempt has been made in the present study to evaluate uplift and lateral ... -
Seismic Behavior of Steel Pipeline Embedded in Controlled Low-Strength Material Subject to Reverse Slip Fault
(ASCE, 8/1/2021)Controlled low-strength material (CLSM) has been widely used for pipe backfilling applications with several advantages, as described in detail in numerous documents. Our previous study indicated that buried pipelines ... -
Transient Simulation and Diagnosis of Partial Blockage in Long-Distance Water Supply Pipeline Systems
(ASCE, 8/1/2021)A partial blockage usually results in undesirable consequences for long-distance conduits. In order to study the disturbance of partial blockages on transient responses, a numerical model was developed to simulate a partial ... -
Effect of Backfill Temperatures on Axial Restraint of Pipelines
(ASCE, 8/1/2021)One consideration for pipeline design is the Delta-T. There may be a tendency to assume a conservative value for winter construction, the extreme value being the air temperature. In applying a low restraint temperature ... -
Determination of Limit Deposition Velocity and Viscosity in Waste Brines Transported in Pipelines
(ASCE, 8/1/2021)The wastewater generated in the potash mines of the Bages region in Catalonia (Spain) was experimentally tested at the Paterson & Cooke slurry test facility in Cape Town, South Africa, to determine the flow behavior ... -
General Models for Optimal Design of Star–Star Gathering Pipeline Network
(ASCE, 8/1/2021)The arrangement of gas gathering stations (GGS) and central processing facilities (CPF) in the natural gas gathering pipeline network really counts. Their reasonable number and locations can make the pipeline network ... -
Standardization of Fixture Units for Modern Flush Valves by Optimizing Water Demand Using Modified Hunter’s Curve
(ASCE, 8/1/2021)Plumbing planners and architects choose to use the 1940s Hunter curve that articulated domestic demand to solve the complex and multifaceted difficulties they found in the probabilistic process. This curve was designed to ... -
Gradient Boosting Coupled with Oversampling Model for Prediction of Concrete Pipe-Joint Infiltration Using Designwise Data Set
(ASCE, 8/1/2021)Infiltration of groundwater through reinforced concrete pipe (RCP) joints under hydrostatic pressure has been a major costly challenge in municipal sewer network systems. Analysis of an exclusive designwise infiltration ... -
Mechanical Behavior Analysis of Suspended Pipelines Caused by Ground Subsidence
(ASCE, 8/1/2021)Long-distance pipelines are prone to suspend due to geological disasters, and large deformation may occur under gravity or other loads. In this study, mechanical behavior of a suspended pipeline caused by ground subsidence ... -
Culvert Renewal with Cementitious-Geopolymer Spray–Applied Pipe Lining: Field Data Collection and Assessment
