Definition of inside and outside the device
Thread Content
While studying the *National Training Manual for Personnel Involved in the Design and Approval of Pressure Pipelines*, I encountered the chapter on road facilities within installations, and I was unable to understand the concept of installations as described in the book. I would like to ask what the exact definition of the inside and outside of the device here is? Can it be understood in a simple and easy way? Is a work area a plant area? Or is a workshop a plant area?
Regarding your question, refer to clauses 2.0.10, 2.0.11, 2.0.12, and 2.0.13 of the \"GB 50160-2008 Code for Fire Protection Design of Petrochemical Enterprises\", and you should be able to understand it. For your reference, the 2.0.10 Process Plant Area refers to an area composed of one or more separate petrochemical plants or integrated complexes. 2.0.11 A multiple process plant is composed of two or more independent units that are arranged together in a compact manner; feed is transferred directly between these units, and there are no intermediate material storage tanks for maintenance purposes. The startup and shutdown for maintenance of such plants take place simultaneously, and they are considered as a single unit. 2.0.12 A process plant is a combination of one or more interrelated process units. 2.0.13 A process unit within a device is a combination of equipment, pipelines, and instruments that carry out a specific technological process in production.
