Section - 8A: General Guidelines for Equipment and Piping Location, Spacing, Distances and Clearances
This article should only be used as a guide. It's intended purpose is to help the piping designer who is responsible for placement of one specific item in a typical refinery, chemical or petrochemical process plant or someone who may need help in developing a total plot plan for a complex unit.
The guidelines given here are based on my many years of experience with one of the world's largest engineering, design and construction companies along with the U. S. OSHA Part 1910 and the NFPA (National Fire Protection Association) Code No. 30.
