Flanges, valves, and other fittings have their own pressure-temperature limits, which are independent of the pipe schedule. The most common standard is , which covers flanges for pipe sizes up to NPS 24. This standard defines flange "classes" (e.g., Class 150, 300, 600, 900, 1500, and 2500), which correspond to a maximum allowable working pressure that decreases as the design temperature increases. A piping system is only as strong as its weakest component; therefore, all flanges and fittings must be rated for at least the design pressure and temperature of the pipe itself.
