What is Pipe Class Ratings and PN Comparison about?
This document compares pipe class ratings and pressure numbers (PN). It provides a table that lists the equivalent ASME flange class and ISO pressure nominal (PN) ratings. It notes that PN ratings do not have a proportional relationship between numbers, while class numbers do. It recommends using class numbers over PN ratings. Finally, it notes that the piping rating must follow the pressure-temperature rating of the weakest component in the system.
