Coatings and Cathodic Protection for Underground Pipelines - What a Corrosion Engineer Should Know
Coatings control corrosion by providing a barrier against oxygen and water. Although coatings are extremely effective, all organic coatings are semi-permeable to O2 and water. The water permeability coefficient of fusion bonded epoxies, one of the best coating systems, is approximately 10 gms/mil/24 hours, but minimum concentration of oxygen and water that can start the corrosion process is 10 ...
متن کاملSaltwater icephobicity: Influence of surface chemistry on saltwater icing
Most studies on icephobicity focus on ice formation with pure water. This manuscript presents studies to understand the influence of surfaces on saltwater ice nucleation and propagation. Experiments are conducted to quantify the influence of surface chemistry on saltwater ice nucleation and to understand the utility of superhydrophobic surfaces for saltwater icephobicity. These experiments are ...
متن کاملInvestigation Results of Properties of Stripe Coatings in Oil and Gas Pipelines
The studies have been done on the navy tube lines, land and the metal workforces that are related to the oil and gas industries, shows that in most cases, weld lines and edge of a sharp regions has been influencing on location of corrosion and eroding of effective thickness of coating film. So by initializing of coating separation is from the surface of tube and the other metal workforces, from...
متن کاملEffect of Montmorillonite Nanogel Composite Fillers on the Protection Performance of Epoxy Coatings on Steel Pipelines.
Montmorillonite (MMT) clay mineral is widely used as filler for several organic coatings. Its activity is increased by exfoliation via chemical modification to produce nanomaterials. In the present work, the modification of MMT to form nanogel composites is proposed to increase the dispersion of MMT into epoxy matrices used to fill cracks and holes produced by the curing exotherms of epoxy resi...
متن کاملWCET Coverage for Pipelines
Hybrid measurement-based (MB) approaches for computing WCET estimates are gaining popularity due to difficulties modelling advanced microprocessor speed-up features. These approaches combine measured data of program segments by using static analysis techniques in order to reconstruct the longest path through the program. To this end, execution times of program segments are collected by first in...
