Adequacy: Piping design must be adequate to meet the process specification and physical conditions in which the plant is to operate.
Economy: Adequate piping technology must be adopted at an economic cost & must be minimized by maximizing the use of standardized methods of detailing and data presentation
Clarity: Much of the piping data is derived from and used by other engineering departments and must be clear, consistent and reliable.
Accuracy: Details of piping and materials must be complete and accurate. Rectification of mistakes in these activities at a later stage may prove to be very costly and can cause heavy financial losses.
Therefore, the basic requirements are:
