Pressure Class Cross-Reference

Compare European (PN / MPa) and American (Class) pressure-rating systems and find the approximate equivalent between them.

Approx. Class

Note: PN–Class correspondence is an engineering approximation (based on nominal design pressure at room temperature), not a mandatory equivalence. Always verify against the applicable standard.
