During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational investigations, such as a Hazard and operability study (HAZOP). To do this, it is critical to demonstrate the physical sequence of equipment and systems, as well as how these systems connect.
Pipelayers should not be confused with pipefitters. Both trades involve pipe and valves and both use some of the same tools. [2] However, pipelayers usually work outside, laying pipe underground or on the seabed, while pipefitters typically work inside, installing piping in buildings or ships. [2] One author summarizes the different tasks this way:
