Piping and instrumentation diagrams (P&IDs) are considered fundamental for companies running process systems. P&IDs play a significant role in the maintenance and modification of the process that it describes and should be maintained to reflect an up to date status. These drawings are critical in demonstrating the physical sequence of equipment and systems, as well as how these systems connect. During design the P&ID provides a basis for the development of control systems allowing safety and operational investigations including a hazard and operability study commonly known as a HAZOP.
The first thing to understand is that P&IDs can’t be created directly from 3D scan data. The data captured from the laser scanner is 3 dimensional whereas a P&ID is drawn in 2 dimension and on occasions in a schematic format.
With our unique 2D P&ID structuring index we are able to quickly and easily create and export .csv files listing asset, equipment and line numbers directly from the CAD file, which later can be used to build or validate your existing asset management system.
ALS has accumulated over 40 years’ experience creating, surveying and updating P&IDs across petrochemical, chemical, detergents, pharmaceutical, food and gas industries. Our experience ensures P&IDs are drawn to a high CAD standards using correct symbology. ALS can advise clients with drawing standards and best practices based on each client’s particular process.
A P&ID is a diagram which shows the piping of the process flow together with the installed equipment and instrumentation. P&IDs enable engineers and even HSE to be able to clearly understand the process and safety features incorporated into the process design philosophy.
