The pipe class may be used beyond the temperature range given after reviewing the usability of each of the piping components included in the pipe class. In such a case the applicable pressure shall be selected based on the relevant codes and standards. 6.2. The maximum pressure given is at the minimum temperature of the temperature range mentioned. For temperatures higher than the minimum value, the corresponding allowable pressure is given in each pipe class. The maximum pressure given in piping classes are less than the maximum allowable pressure of flanges given in ASME B 16.5 for that flange rating. In such cases, the pressure temperature rating chart in the piping class is indicated in “italics”. 6.3. Service category indicates if the pipe class is suitable for the service category “A” or “B” as given in ADMA-OPCO Code of Practice CP-111. Since service category A has stringent requirement in CP-111, pipe class with service category-A is also suitable for fluids with service category-B.. Pipe Class.
