After establishing a 3-D model in PDMS, SP3D, or any other software, Piping designers have to communicate the same information to the person who is executing that piping job either in the yard for fabrication or in the field for Erection/Construction. The conveyed information must be enough for the execution person. So that, they can understand well and get a vision of the fabrication of Spools and how the piping is connected with other equipment or special items.
Here comes the role of Piping Isometric drawing. This kind of drawing helps a designer to transfer his vision of piping connections to the team executing construction projects. Piping isometric is a representation of a single pipe line in a process plant with exact dimensions and Bill of Material (BOM). It is the most important deliverable of any project where piping plays a vital role.
By Definition, Isometrics drawings are a graphic representation of a 3D routed line in a 2D plane that combines height, length of pipe in a single drawing with a 30º angle on both sides from horizontal.
The main body of a piping Isometric drawing is consist of:
Weld joint type and its location
Continuation isometric number
Co-ordinates and Elevation of Pipe
Connection details with equipment
Section of Left or right of Piping Isometric drawing includes:
