This in relation to pressurized pipe.

Many people use working pressure and operating pressure interchangeably. However, I don't believe the ANSI piping codes use the word rated pressure for piping systems. I believe it uses the term design pressure to define the maximum safe pressure at which a system can be operated.
The only place I can recall the code using the term rated or rating is with regards piping classes or flange ratings. It has been over ten years since I have had reason to look at the ANSI code but I believe I am correct.
The main point I would like to make is you need to be very careful what terms you use so that they are consistent with the codes you are using.

Rated pressure is the maximum safe pressure the pipe can handle. Working pressure is the pressure exerted by the fluid or process of which the pipe is a part of. It is lower then the rated pressure.

Working pressure is the nominal required operating pressure the pipe will be exposed to during normal operation. Rated pressure is the maximum safe pressure the pipe can be exposed to. Then there is the "burst pressure" which is the fracture point of the material.
