Pressure Ratings for Pipes, Tubes and Fittings (PDF)

All Pipes and various pipe fittings are most commonly classified based on their pressure temperature rating or commonly known as P-T Rating. So, the pressure rating (also known as pressure class) is the maximum pressure a pipe, fitting or valve should be capable of withstanding at given temperature in normal conditions.

So Pressure and Temperature Rating tables of ASME codes provide a limit of Maximum working pressure at which the flange can be subjected for longer duration at a specified temperature. For intermediate temperatures, linear interpolation can be done.

Also known as Maximum Allowable Working Pressure (MAWP), a pressure rating lets an engineer determine which material will work best at any certain point of piping system.

The most common way of specifying pipe pressure temperature rating is given by ASME 16.5, using pound ratings (or lb ratings) – #150, #300, #400, #600, #900, #1500 and #2500. The pressure rating or pound rating for a pipe is determined using the design pressure and design temperature for the pipe.
