How to determine the explosion protection rating? Which major determines it?
Thread Content
Before the design of a chemical engineering project begins, flammable and explosive substances need to be classified into categories, such as Class A or Class B, or other categories; this classification is determined based on the flash point of the substance； So, how is the explosion protection rating determined? For example, if this product contains propylene or DMAC, how can the explosion-proof rating be determined based on these components? Was it determined by the process engineering department? Was it also decided by the electrical engineering department?
Determined by the process engineering team; the process is clear
The process engineering department provides the source locations and preliminary layout diagrams, while the electrical engineering department creates the explosion-proof zoning diagrams based on the process requirements; the explosion-proof classification is determined using these diagrams
The classification of explosion-proof areas is determined by electrical factors. Of course, the degree of hazard is first determined through the engineering process, and then provided to the electrical team so that the explosion-proof areas can be identified
The process is based on the preliminary layout diagrams prepared by the pipeline layout team to identify the source of release and to determine the electrical explosion-proof zones.
I think so too! Are you from a design institute? Is that what you do?
