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.

They are excellent starting point in visualization and design and are often used to supplement multi view drawings.Īn isometric drawing is one of three types of axonometric drawings they are created based on parallel projection technique. They tend to present images of objects in a form that mimics what the human eye would see naturally. Pictorial drawings consist of visible object faces and the features lying on the faces with the internal features of the object largely hidden from view. The principal dimensions are the limits of size for the object along the three principal directions. Piping isometrics drawing are a type of pictorial drawings that show the three principal dimensions of an object in one view. This topic of discussion gives basic information for piping isometrics, its preparation details, drafting requirements, material take off in isometrics, supports etc. Introduction to Piping Isometrics Piping Isometrics Introduction
