P & ID (Piping and Instrumentation Diagram: The drawing includes piping systems, equipment, instrument and control signals (Get detailed instructions in other documents). Therefore, this document can not be used for the process engineer or related issues in the design and procurement. The course content is limited to the monitoring, the piping engineer newly graduated should remain many shortcomings. There is a no size but stature most important (P & ID), there are drawings of size but not right ratio (isometric), with drawings only show ground floor (Piping GA ), have detailed drawings to each section (Pipe Support).
The drawing is the main base to manufacture and install and test the simple to the more complex device clusters, so the information from drawings provided are varied and plentiful. In general engineering and the petroleum industry in particular is drawing the main tool for the development of design ideas to actual construction.
