In petrochemical industry, process piping is mostly carbon steel pipes, up to 12″ size. Because of process requirement, piping is exposed to very large temperature range and piping routing required special consideration. Since almost all refinery plants has same type of equipment, we can at least have some guidelines, if not standards, for pipe routing concerning each type of equipment.
Piping design
Mining piping
In mineral processing industry pipe routing and design is different from petrochemical piping. Temperature range is small, but pipes are larger and transporting medium is slurry or paste. Slurry transportation is big and complex subject and all aspects of slurry transportation cannot be presented in just one blog.
Nozzle orientation
Exchanger nozzle
The manufacture’s outline will show suggested nozzle location. The piping designer should be aware that nozzle location and arrangement can be changed to suit piping design.
Underground gravity piping
In this blog I will review underground gravity pipes – oily water, potentially oily water and storm water. Please do not get confused with terminology since other plants might have other terms for the same services. For example some plants will use term contaminated rainwater sewer for potentially oily water.
