Construction crew use the isometrics to mark the actual versus the designed dimensions and use colored markups to show the deviations. Isometric drawings are very important for all engineering concerns, but Isometrics Drawings of Piping Systems are particularly relevant for EPC companies in the Oil and Gas sector because it brings clarity to contractors, construction crew and the overall project regarding the general arrangement drawing. Isometrics are also called Iso – are oriented on the grid relative to the north arrow on drawing plans. Isometric Piping Design is typically drawn on pre-printed paper with lines of equilateral triangles form of 60 degree. Symbols used for fittings, valves and flanges are modified to scale to the isometric grid. If the piping system is complicated, then individual pipe runs are represented on separate isometric diagrams.īut piping isometrics are different from orthographic drawings, in that the drawing shows the pipe in a way that the length, width and depth are detailed in a single view.Must also include a table that lists the numbers and description of each type of fittings represented in the drawings.All other components such as flanges, valves, elbows, and other fittings need to be clearly drawn.The environment: that is the operating and process conditions (temperature and pressure) for the pipe run should be ideally conveyed on the isometric.The line number indicates the fluid service, piping class and material, insulation details etc. Indicating the line numbers for pipe runs clearly within the drawing.It shows the straight lengths of all the pipe runs on the drawing as clearly as possible.Isometric drawings typically portray a graphical representation of the 3D piping system.What Kind Of Data Is Typically Conveyed In Piping Iso Drawings? Isometric drawings are comprehensive documents that hold valuable info used by different project stakeholders at different times.

Isometric is one of the most important part of the overall piping design engineering project. The term Isometric originates from the Greek word ‘isometros’ (of equal measure) – meaning objects measured with the same unit. The importance of isometric drawings can be seen as below: With the help of sophisticated computer aided design (CAD) tools, piping engineers and designers can produce isometric drawings from 3D models with ease. An isometric drawing is nothing but a detailed orthographic drawing that represents the details of 3D structure of the piping system in a 2D format. It is a standard practice for engineering companies to create isometric drawings of piping systems to present all details in –depth.
