"Pressure of not more than 33% above the design pressure at the temperature of the increased condition is permitted
for a maximum of 10 hours at any one time and for less than 100 hours per year,
provided the restrictions in Par. 11.3.4 are met."
To comply with B31.3 you also need a means to measure and document overpressure occurrences.
The main impact of operating above a pipe's design pressure is administrative i.e. are you following acceptable Industry standards. If not, some legal issues may be triggered.
There is no legal exposure operating below the design pressure if the pipe is designed to Code.
It is gross negligence to operate above the hydrotest pressure.

If you have a flammable. cumbustable or toxic liquid and you operate above the design pressure, the lawyers may come to knock on your door.
Flanges commonly (but not always)leak before piping fails....
