Piping is a system of pipes (hollow, cylindrical tubes) used to convey liquids, gases and sometimes other materials from one location to another within industrial facilities such as petroleum refineries, chemical and petrochemical manufacturing, natural gas processing, electricity-generating power plants and many others. The adjacent photo depicts a complex piping system in an industrial plant.
Industrial plant piping and the accompanying in-line components can be manufactured from various steel alloys, titanium, aluminum, copper, glass or various plastics. The in-line components are known as fittings and valves. Process control systems use in-line sensors and control valves to monitor and regulate the desired temperatures, pressures, flow rates and process vessel liquid levels of the fluids being transported and processed. Piping and control systems are documented in drawings referred to as Piping and Instrumentation Diagrams.
Piping design
The engineering discipline of piping design studies the efficient transport of fluid.[1][2]
Process piping and power piping are typically checked by pipe stress engineers to verify that the routing, nozzle loads, hangers, and supports are properly placed and selected such that allowable pipe stress is not exceeded under the appropriate ASME code.[3][4] This checking is usually done with the assistance of a (finite element) pipe stress analysis program such as Caesar II, ROHR2, CAEPIPE and AUTOPIPE.
Plumbing
Plumbing is a piping system that most people are familiar with, as it constitutes the form of fluid transportation that is used to provide potable water and fuels to their homes and business. Plumbing pipes also remove waste in the form of sewage, and allow venting of sewage gases to the outdoors. Fire sprinkler systems also use piping, and may transport potable or nonpotable water, or other fire-suppression fluids.
