Corrosion rate and pipe design

By
Corrosion is a serious issue. However, corrosion engineers are rarely asked about it during the designing of components. It is only when the components fail that people remember there are people who have studied corrosion for their whole life and would provide a solution. The design problems are really quite simple, and the loss of money could have been avoided had the company bothered to involve a corrosion engineer in the first place. Let me illustrate this with an example of a factory near the sea. Suppose a mild steel pipe is fitted inside the factory to transport 1 wt. % hydrochloric acid. The engineer has a choice between selecting pipes of 5 mm and 10 mm thickness. To save money, they go for the pipe with the 5 mm thickness because it has been 'successfully used by the other customers'. Over the course of a year, it is seen that the pipe has started leaking at certain places. Further investigation reveals that those sections have thinned to half of their thickn...

What is a Corrosion Loop - PART 2 - EXAMPLE

By
How to prepare a corrosion loop? To prepare a corrosion loop, the person in charge will look at the overall picture and answer the following questions - 1. What is the process? 2. What are the components? 3. What are the materials for each component? 4. What are the common features among them? 5. Where does the commonality end? -  This is important as that will mark the beginning of a new corrosion loop. 6. Can I use the same inspection procedure for all of them? 7. Do they corrode/get damaged in the same manner due to the same reasons? WATCH THE VIDEO FOR A DETAILED EXPLANATION -       Read part 1 here! https://corrospective.com/ 😀Happy learning! 😀

What is a Corrosion Loop - PART 1 - CONCEPT

By
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.  Source: Rachman, A. and Ratnayake, R.M.C. (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! 😀
