Actual line size can be obtained from BOM or NB (nominal bore) mention in isometric. The line diagram shown in the isometric drawing can’t define line size.All isometric drawings are prepared irrespective of Line length and size as well as piping components but this gives the exact dimension of everything mentioned in the drawing.Some important feature of any piping isometric is as follows:

Isometric drawing is a 2D drawing that enables a person to get a vision of a 3D view of a line. More Resources: Heat Tracing in Piping: Types, Working, Use, Installation, Comparison (Steam Tracing vs Electrical Tracing) Features of Piping Isometric Drawings

The volume of Water required for hydro testing: π x ² x Length of Pipe.

Weight of Pipe: π x diameter of the pipe (in m) x length (in m) x thickness (in mm) x density of pipe material.

Insulation Area (in m²): (all in meter) x Length of Pipe ( in meter ).

Inch Dia: Size of Pipe joint ( in inch) x No, of Joints.

Inch Meter: Length of pipe (in meter) x Size of pipe ( in inch ).

The main body of a piping Isometric drawing is consist of: It is the most important deliverable of any project where piping plays a vital role.īy 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. Piping isometric is a representation of a single pipe line in a process plant with exact dimensions and Bill of Material (BOM). This kind of drawing helps a designer to transfer his vision of piping connections to the team executing construction projects. Here comes the role of Piping Isometric drawing. 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. The conveyed information must be enough for the execution person. 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.
