Modeling the Behavior of Smart Oil Well Cements and Offshore Pipe-Soil Interaction in Very Soft Soil
… gas production infrastructures from borehole to pipelines. Rheology properties and hardening characteristics are some of the important parameters for cementing slurry during installation. Also over the last decade, health monitoring of the plugging material during service life became more …

An evaluation of rural public water systems
… not be ignored as has been done in some cases. Plastic pipe, utilized for its economic benefit, was found to be generally satisfactory. Criteria other than those recommended by FHA are suggested for domestic water consumption, instantaneous flow rates, and distribution storage. Finished water …

Low-Cost Grain Bin Moisture Sensor Using Multiple Capacitive Elements
… of wheat samples in a six inch by five foot plastic pipe. Grain with different moisture levels from 9.7% wet basis (w.b) to 16% w.b. was used. The sensor accuracy was found to measure grain moisture content to ±0.5% w.b. for the majority of cases, and ±1.5% w.b. for all tested cases. A number …

Evaluation of Strength and Hydraulic Properties of Buried Pipe Systems Used for Stormwater Harvesting
… In this study, high-density polyethylene (HDPE) pipes used as an underground storage was evaluated and a Microsoft EXCEL based model was developed, called PIPE-R Model. To study the structural integrity of the pipes, laboratory and field testing were conducted. For the water harvesting, UCF …

Nitrification in premise plumbing and its effect on corrosion and water quality degradation
… biofilms. But with nitrification and in pipe materials that are relatively non-reactive with chlorine, chloramine was much less persistent and less effective than chlorine. In materials that are reactive with chlorine such as iron pipes, the relative efficacy of chloramine versus chlorine …

Assessing the Potential of Granular Activated Carbon Filters to Limit Pathogen Growth in Drinking Water Plumbing Through Probiotic Versus Prebiotic Mechanisms
… biofilms that form within the interiors of pipes and fixtures that deliver drinking water to the point of use. These pathogens are especially problematic within premise (i.e., building) plumbing, where intermittent use throughout the day leads to long periods of stagnation, increased water …

Impact of Premise Plumbing Conditions, Materials, Corrosion Control, Temperature, and Water Heater System Design on the Growth of Opportunistic Pathogens in Drinking Water
… Review of the Propensity of Premise Plumbing Pipe Materials to Enhance or Diminish the Growth of Legionella and Other Opportunistic Pathogens." It examines the complex environments found in premise systems, focusing primarily on the role of pipe materials. The effects of metallic (copper, …

Accelerated Testing Method to Estimate the Lifetime of Polyethylene Pipes
… material more rapidly. In the case of polymeric pipes, previous studies have shown that there are two possible time-dependent failure mechanisms corresponding to ductile and brittle failure. The ductile mechanism is evident at shorter times-to-failure and results from the stretching of the …
