2. Piping Avoidance Areas
According to Pipe Routing guidelines, what areas should piping avoid?
Explanation: Piping should avoid areas designated as equipment and instrument maintenance space, vertical access hatches, crane and monorail travel spaces, and normal personnel access and egress lanes.
3. Bottom-Supported Piping while Pipe Routing
How should bottom-supported piping with no insulation or with insulation for personnel protection be routed?
Explanation: Bottom-supported piping with no insulation or with insulation for personnel protection shall be routed with bottom of pipe (BOP) resting on top of steel (TOS) or top of concrete (TOC).
4. Drain Piping to Oily Water Sewer Drain Cup
What should be the distance between drain piping and the top lip of the oily water sewer drain cup?
Explanation: Drain piping to an oily water sewer drain cup shall stop 1 inch (25mm) above the top lip of the drain cup.
5. Minimum Pipe Size in Pipe Rack
What is the minimum pipe size allowed in the pipe rack?
Explanation: The minimum pipe size in the pipe rack shall be 2 inches.
6. Piping Sizes Not to be Used
According to Pipe Routing, in which cases should piping sizes of 3/8 inch, 1-1/4 inch, 2-1/2 inch, and 5 inch not be used?
Explanation: Piping sizes of 3/8 inch, 1-1/4 inch, 2-1/2 inch, and 5 inch should not be used unless mating to these sizes on equipment and instruments.
7. Pipe Size Change at Equipment Connection
What should be done at any mechanical equipment connection for piping sizes of 3/8 inch, 1-1/4 inch, 2-1/2 inch, and 5 inch?
Explanation: At any mechanical equipment connection of piping sizes 3/8 inch, 1-1/4 inch, 2-1/2 inch, and 5 inch, the size of the connecting piping shall be changed to another size immediately adjacent to the equipment or the compatible fitting(s) shall be provided by the equipment vendor.
