Cool coatings can play an important role in reducing global energy consumption and increasing interior comfort. They do this by minimizing solar absorption on a surface whilst maximizing thermal emission. Used in this way, a cool coating is able to reduce the flow of heat from the exterior coated surface into the building, resulting in lower internal temperatures.
Energy producing companies use pipelines to transport energy from point A to point B. When the pipeline thickness at a location falls below a certain threshold, there is risk of leakage that could result in serious economic losses, personal injury, or damage to the environment. Pipeline integrity management is a performance-based process that handles pipeline serviceability and failure prevention.
It is well understood that unless a surface is properly prepared prior to the application of a coating or surface treatment, adhesion and the expected lifetime of the material is quite minimal. Preparation generally falls under one of two options: either utilization of particle or grit-blasting, or the use of waterjetting. Typically, waterjetting of surfaces in preparation for application of coatings or surface treatments is only conducted on metal substrates that contain a previous profile from either operational wear (corrosion pitting) or previously abrasive blasted surfaces.
Asbestos containing textured coatings and other various asbestos containing components are not often thought of as being used on bridges. However, their use on bridges, especially concrete bridges is widespread in some regions and because of this, specific regulatory compliance is required. Knowing how to comply and how proper abatement is performed will keep the contractors and facility owners in compliance, avoid associated liabilities, provide proper employee safety and keep bridge maintenance projects on schedule.
This paper focuses on a case history and projects that involve both multiple design teams and contractors to demonstrate how establishing a centralized corrosion control program benefits the utility owner, and to also point out the challenges.
The potential for structural alloys to undergo environmentally assisted cracking in molten salts is relatively unexplored due to their limited industrial application. However, fluoride salts are of prime interest to many advanced reactors including the Kairos Power FHR reactors. Table I summarizes literature studies of EAC in molten fluoride salts. For the ten studies shown, seven are for Ni-Mo-Cr family of alloys (INOR-8 / Hastelloy N or variants) that were used in the Molten Salt Reactor Experiment (MSRE), two studies investigate austenitic stainless steels, and there is one report of EAC in oxygen free high conductivity (OFHC) copper.
The power generation industry is seeking solutions to prevent failures in high energy piping systems including main steam and hot reheat steam pipelines. A thorough review of prior failures in these systems has shown that 60-70% of all failures can be attributed to hanger and strain monitoring systems not performing within specification for extended periods of times (typically 1-5 years). The typical failure mode has been creep in seam welds. The consequence of failure for high energy piping can be severe and the effect of unexpected or unknown displacements cannot be quantified when estimating remaining life.In this case study we developed wireless LIDAR sensor networks that can be installed on either hangers or above insulation on these piping systems. The purpose of the sensor network is to protect life property and environment by reducing the likelihood catastrophic failures of high energy piping. The wireless sensors would communicate with the central control system at a power station and alert plant staff when the piping strain / bulk displacement is outside of design limits. A Bayesian network model was created which links the piping displacement to the remaining creep life predicted based on API 591 “API 579-1: Fitness-For-Service”. Therefore by knowing real-time pipe displacement measured using wireless sensor network the remaining creep life can be dynamically predicted though the Bayesian network model.
There is considerable interest in molten halide salts for several applications including thermal storage and next generation nuclear reactors. While molten salt as a working fluid and/or fuel media offers advantages, salt compatibility with structural and functional materials is a concern. Various reports in the literature suggest that chloride and fluoride salts can be highly corrosive to structural alloys but do not always clearly describe how the salt was handled and dried/purified prior to and during the corrosion experiment.
