51316-7363-Suitability of High Alloyed Materials in Molten Salts at 600 °C

Product Number: 51316-7363-SG

ISBN: 7363 2016 CP

Due to the composition of heat transmission media and temperatures, service conditions in solar facilities are, in many cases, extreme in terms of corrosion. By electrochemical measurements and exposure tests, the suitability of two alloys - X8NiCrSi38-18() and NiCr25FeAlYB - in molten nitrate salt (60 % NaNO3/40 % KNO3) was characterized at 600 °C.

Classification Of Active And Passive Conditions Based On Different Relaxation Response For External Corrosion Coated Pipelines

External corrosion on buried pipelines can result in gradual and usually localized metal loss on the exterior surface of failure coating, resulting in reduction of the wall thickness of the metallic structure. Indirect technologies, such as DC basis (i.e. DCVG, CIPS) have been able to detect and pinpoint two conditions in the pipeline, intact and holiday (active surface or coating anomaly) with good confidence. Classic DC methodologies monitor and characterize the state of the coating and effectiveness of cathodic protection by using transfer function principle (i.e. resistance). The formation of an electrochemical cell, such as buried coated pipeline with cathodic protection (steel in electrolyte) is formed at macro scale conditions [1-2]. The expected damage evolution of the coated pipeline includes the electrolyte (soil+water) uptake within the coating
