Important terms in API certifications - CRV & IOW - I

CRV stands for critical reliability variables.

It notes the variables, i.e. parameters which are the most important in damaging the reliability of the equipment.

In simple terms, it is that parameter which if changed will damage your equipment.

This parameter is important in risk-based inspection.

It helps to note the exact parameters, may be temperature, pressure, pH, which will increase the risk of corrosion and damage.

What is a Corrosion Loop - PART 1 - CONCEPT

Corrosion loop is used to simplify inspection procedures in refining processes. Corrosion loop is defined as a group of components with common materials, processes, and operating parameters.

(2020), "Corrosion loop development of oil and gas piping system based on machine learning and group technology method", Journal of Quality in Maintenance Engineering, Vol. 26 No. 3, pp. 349-368. https://doi.org/10.1108/JQME-07-2018-0058 It is needed when the scenario has - 1. Complex process 2. Several variables such a materials of construction, process parameters, functions 3. Multiple damage mechanisms WATCH THE VIDEO FOR A DETAILED EXPLANATION - Click here for part 2 ! https://corrospective.com/ 😀Happy learning! 😀

Isocorrosion chart snapshot

concept Isocorrosion chart Use Estimate corrosion rates for an alloy Select an alloy for a particular application with specific parameters Definition A plot of temperature versus electrolyte concentration, with lines depicting combination where similar corrosion rates are found example how to use it? An application needs a temperature and concentration as depicted by point 1 in the image above. We can plot it on the isocorrosion chart for that alloy and estimate the corrosion rate. The design of the component and corrosion allowance can be decided accordingly. A method to determine the suitability of the alloy for an application and electrolyte-temperature combination.
