![]() ![]() No attempt is made to represent a pipe’s actual size or pound rating graphically. Isometric symbols for fittings, flanges, and valves represent all sizes of pipe. Isometrics are also drawn as a schematic, which means they are not drawn to scale. The isometric must provide a detailed description of the pipe’s routing from beginning to end. Piping isometrics are typically drawn in single lines irrespective of the pipe’s size, with each pipe line drawn on a separate sheet. Most engineering and construction companies draw a piping isometric of every piping configuration to be installed in the facility. Once drawn and properly dimensioned, isometrics are provided to fabricators who will build each piping configuration.Īfter configurations are fabricated, isometrics serve as an aid to the construction and erection of the facility by providing workers with the locations of tie-ins, connections, and routings ![]() Isometrics are also used by many companies as fabrication drawings. Piping material take off is generated from isometrics in which each individual component that makes up a pipe configuration is tabulated for purchase or procurement. Isometrics in a single view provide a pictorial representation of the height, width and depth dimensions in a single view to provide a pictorial representation. ![]() In isometric drawings, the three principal axes make equal angles with the image plane. An isometric drawing is one of three types of axonometric drawings they are created based on parallel projection technique. ![]()
