:"For other uses, see
Pipe ."Withinindustry , piping is a system of pipes used to conveyfluid s (liquid s andgas es) from one location to another. Theengineering discipline of pipingdesign studies the efficient transport of fluid.

wood ,glass ,steel ,aluminum ,plastic ,copper , andconcrete . The in-line components, known as fittings,valves , and other devices, typically sense and control thepressure , flow rate andtemperature of the transmitted fluid, and usually are included in the field of piping design. Piping systems are documented inPiping and Instrumentation Diagram s. If necessary, pipes can be cleaned by thetube cleaning process.Plumbing is a piping system that most people are familiar with, as it constitutes the form of fluid transportation that is used to provide potablewater and fuels to their homes and business. Plumbing pipes also remove waste in the form ofsewage , 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.Piping also has many other industrial applications, which are crucial for moving raw and semi-processed fluids for refining into more useful products. Some of the more exotic materials of construction are
titanium , chrome-moly and various other steelalloy s.Pipe stress analysis
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.
