Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another. The engineering discipline of piping design studies the efficient transport of fluid. Industrial process piping (and accompanying in-line components) can be manufactured from wood, fiberglass, glass, steel, aluminum, plastic, copper, and concrete. The in-line components, known as fittings, valves, and other devices, typically sense and control the pressure, flow rate and temperature of the transmitted fluid, and usually are included in the field of piping design (or piping engineering), though the sensors and automatic controlling devices may alternatively be treated as part of instrumentation and control design. Piping systems are documented in piping and instrumentation diagrams (P&IDs). If necessary, pipes can be cleaned by the tube cleaning process. This Database was designed to perform Process Piping & Pipeline Cost Estimates, based on generic cost curves for several Activity families types generated using benchmarking techniques. The benchmarked curves give Mhrs and Cost information as a function of a capacity variable or combination of variables. The cost curves and other information contained in this application can be used to develop the overall process plant capital cost.
