Piping engineering and its management

The starting point for piping design, as for all disciplines, is the development of design criteria. The essence of these is the system of materials specifications, as previously discussed, but several other aspects must be addressed. Previous project design criteria are invaluable as a starting point the following are a few of the more important contents. 

The fundamental tool for the management of piping work is the pipeline (or line) list. This lists each pipeline and usually includes its number, process service and material specification (possibly included in the numbering system), origin and destination, diameter, and process conditions of pressure and temperature. Test pressure and requirement for insulation may also be shown, if not considered obvious from the design pressure and the material specification system, and there may be a requirement for special remarks, such as the need for pickling the hne. 

Problems sometimes encountered in the preparation of this list include the following.
