In every field of profession, there are some abbreviations used frequently. In Piping too, there are many frequently used abbreviations that a piping professional must know. Here we are providing you a list of abbreviations that you should keep in mind while reading a Piping isometric drawing or doing fabrication and Erection work.
How abbreviations are useful in Piping?
For describing anything in the piping isometric drawing there are lots of abbreviations used frequently to understand the vision of the designer. A designer can’t type all description for specifying everything on Isometric. This will take huge work effort as well as will be time consumable. abbreviations are much helpful in the following manners:
- This gives a complete description of pipe fittings in fewer words. For e.g: POE x TOE has simply meant that a fitting required with “Plain one End and Threaded One End“.
- With help of it, communication becomes easier. For e.g.: Instead of asking “TOP of Steel”, it is much easier to ask TOS of structure.
- This gives you a clear understanding of what the designing person wants to describe to you about something.
