Environmental management groups are cracking down on industries by imposing tighter discharge limits and making industries everywhere contemplate in-house pretreatment programs—and dilution is no longer an acceptable solution.

Interpreting Piping and Instrumentation Diagrams

. by Robert Cook

Learning to read and interpret piping and instrumentation diagrams via dry text-based articles (unlike those produced by yours truly) can be painful. To make this critical topic a bit more engaging, a series of videos intended to complement the series provided here are offered. They review the fundamentals of virtually every aspect of symbology and tag application.

Interpreting Piping and Instrumentation Diagrams-Symbology

. by Robert Cook

Get a thorough explanation of symbology as it relates to Piping and Instrumentation-controls symbology, tag identification, I/O devices, valve symbol, primary flow element, horizontal line types, dashes, and more.

As I mentioned in Part 2, the meanings of the various symbols used on P&IDs (aka, symbology) are defined on separate drawings called “Lead Sheets” (or Legend Sheets). These are your “secret decoder rings” to P&ID symbology interpretation. Every company that builds process plants should have a set of lead sheets customized to their particular ways and means.
