What is API 936 and what does it cover? Which aspects of refinery engineering are covered by API 936 today? Why is it important to inspect refractories in accordance with API 936 requirements? These are some of the most frequently asked questions in our TheAnees.Com FAQ sections and in our tea office of the inspection department.
What is API 936 and what does it cover?
In 1996, The American Petroleum Institute (API) developed and published API 936, Refractory Installation Quality Control-Inspection and Testing of Monolithic Refractory Linings and Materials, which provides installation quality control guidelines for monolithic refractory linings and may be used to supplement owner specifications.
Which aspects of refinery engineering are covered by API 936 today?
A very simple example of refractories in an oil refinery’s fluid catalytic cracking unit (FCCU), refractory is primarily used for its abrasion and heat resistant properties. Other processing units, such as sulfur recovery facilities, use it for its chemical and heat resistant qualities. Refractories are used to meet a variety of needs, including heat resistance, abrasion resistance, and chemical resistance.
Why is it important to inspect refractories in accordance with API 936 requirements?
The act of inspecting the physical condition of monolithic refractories in order to determine if and for how long they will perform as intended is known as refractory inspection. The primary aim of refractory is to remain stable and efficient in harsh settings; if it fails, the risk of asset life reduction increases; therefore, such failures should be avoided. Inspection intervals and inspection methodologies are pre-determined.
Why are the API 936 Personals numbers so less?
API 936 certified personals are not like other API inspection certified personals such as API 510, API 570, and API 653, because they’ve defined needs, which is why more people are interested in them, but for API 936 there are no defined needs. The second reason for the lower number of API 936 certified people is due to lower encouragement than other API ICPs in the market. On the other hand, in the inspection field, if you want to be a good inspection professional, you must have a strong grasp of API 936 refractory inspection, just as you must have a strong grip on other required inspection certifications. All required assets are open for inspection, maintenance, and/or required work during every major turnaround, special shutdown, emergency shutdown, or other opportunities. That’s when a API 936 certified person’s appearance is required for inspection, material selection, and installation because a certified person knows all the requirements as per standards to control quality aspects.
