What is Isometric
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.
Piping isometrics allow the pipe to be drawn in a manner by which the length, width and depth are shown in a single view.
Isometric drawings are commonly used in technical drawing to show an item in 3D on a 2D page.
Isometric drawings, sometimes called isometric projections, are a good way of showing measurements and how components fit together.
1.SOME IMPORTANT CHECK LIST FOR ISOMETRICS.

- Shoe Not Required For Condansate Line When Line Will Be On Pipe Rack.
- Nozzle Orientations Should Be Keep As Per Piping Requirement.
- Avoid The Obstacles. Keep A Piping Routing Neat And Clearly.
- Control Stations Locates Side Of Near The Walls Or Columns
- Give A Trunion Supports To Control Station Both Side Of Control Valves.
- Use A Dike Wall Around The Equipments For Avoid The Liquid To Spread In The Plant Area. The Volume Of Dike Wall Is 1.5 Times More Than Total Capacity Of Equipments.
