The propagation of localized corrosion on API 5L X65 carbon steel in hydrogenocarbonated solution containing chloride ions was monitored during long immersion times by electrochemical noise (EN) measurements ZRA mode. Monitoring from the EN amplitude is possible but interpreting potential and current transients after made difficult different processes (metastable or stable pits, crevices, produ...

A novel method to classify the aggressiveness of soil considering its physicochemical content and development new synthetic solutions for lab uses is proposed. The results showed that main criteria existing in literature corrosivity classification might cause misunderstandings about real aggressiveness. proposed aim cover a wide range found worldwide order refine assessment their characteristic...

Low-carbon steel is widely used in industrial pipelines, and corrosion studies are focused mostly on erosion-corrosion, its prediction control. In this paper, the rate pipelines modeled using a flow loop measured by linear polarization resistance method (LPR) 3-electrode setup for API-5L-X65 QT steel. Optical microscopy SEM conducted to examine surface of sample products. The effect NaCl concen...

The present study is aimed to conduct the experiments in various corrosive environments at various temperatures and constant partial pressures of carbon dioxide (CO2) under dynamic condition to understand the basic mechanism and corrosion resistance of carbon steel. Usually, API grade steels are used in the pipeline for carrying the crude oil and gas. Corrosion problems constitute the major ope...
