Step-by-step explanation:
The main purpose of a single line piping drawing over a double line piping drawing is simplicity and clarity.
Single line piping drawings use a single line to represent pipes, equipment, and connections, making it easier to understand the overall layout of the system. Double line piping drawings, on the other hand, use two lines to represent pipes, providing more detailed representation.
Single line piping drawings are commonly used for initial design and conceptualization, providing a high-level overview of the system. They are also easier to read and understand, reducing the possibility of confusion during construction or maintenance.
