Coatings are essential for protecting structural steel bridges from corrosion in harsh environmental conditions. The selection of a suitable coating system can significantly impact the performance and longevity bridge as well its footprint. This study investigates U.S. Canada’s ISO corrosivity map general environments to which exposed. Additionally, data road maintenance practices transportatio...

For enhanced engine performance, corrosivity of the coolants would play a significant role. In this work, corrosion investigation was performed on cast iron material in pre-mixed coolant environment to understand threshold limits contaminants. The contained combination organic additives viz. sebacate (SA), 2-ethylhexanoate (2-EH), and tolyltriazole (TTA) with varying concentrations chloride con...

The molten-salt catalytic conversion of biomass into synthetic fuels is one the promising renewable energy topics 21st century. Mixtures Zn–Na–K//Cl have gained attention, acting as catalytically active heat transfer fluids in process, due to their low costs and principally melting points which effectively lower required operating temperature reactor. Herein, corrosion behavior three candidate ...

European "Technical Recommendations" have proposed, in addition to the use of substance concentrations, a pH (≤ 2 or ≥ 11.5) and an acid / base buffering capacity classify waste into according their hazardous properties HP 4 'Irritant' 8 'Corrosive'. Buffer refers 2018 UK classification guide referring 'corrosive' level method proposed 1988 for substances preparations but not retained EU regula...

Potential health effects of drinking water quality changes caused by acid precipitation are presented. Several different types of water supply are discussed and their roles in modifying acid rain impacts on drinking water are explained. Sources of metals contamination in surface water supplies are enumerated. The authors present some results from their research into acid rain impacts on roof-ca...

The presence of H2S ( hydrogen sulphide ) gas in oil and gas exploration can give rise to critical safety problems because of its corrosivity and toxicity. In order to protect people and equipment, there is a need for a real-time,remote and reliable seneor that can detcet the concentration of H2S gas. The best way to monitor H2S gas concentration is optical-electrochemical sensor technology. At...

Dwr Cymru Welsh Water supplies over three million people with drinking water throughout most of Wales (UK). Ortho-phosphate has increasingly been dosed at around 1 mg/L (P) to further reduce the corrosivity of supplies to the lead pipes which connect approximately 30% of houses to water mains in the company's area, additional to long-establish pH adjustment measures. The installation of new ort...

Abstract The study’s goal is to analyze the suitability of sub-surface water Una district for drinking and agriculture purposes. data related physico-chemical parameters groundwater was obtained from Central Groundwater Board’s website compared BIS standard (10500:2012). values Ca 2+ , Cl − F SO 4 2- were found be below acceptable limit. pH, TDS, Alkalinity, Mg TH, NO 3 had that above limit at ...

Abstract Concentrated solar thermal technologies play an essential role in the energetic transition which is currently facing our society. The energy generation this technology vastly depends on optical behaviour of reflector materials field. Corrosion reflectors might be issue locations with high corrosive environments because excessive corrosion mirror could catastrophic for profitability con...
