Course Description
This course discusses the design, installation, inspection, and repair of refractory systems for processing & power generation applications in pressure vessels, piping systems, and fired equipment. The discussions include practical examples of refractory systems in demanding applications (such as FCCU's, Fluid Cokers, process vessels, fired heaters and steam generation equipment) and are illustrated by photos and a video. The course will present these topics in the context of API Recommended Practice 936 Guidelines for Refractory Installation Quality Control. Attendees will be well prepared to challenge the API 936 Inspector certification exam upon completion of this course.
The Training Course Will Highlight ?
Training Objective
Target Audience
This course is intended for individuals who are responsible for the design, installation, inspection, or repair of refractory systems in refinery, power generation and petrochemical applications
Training Methods
This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations.
