What is the difference between “Rated Pressure” and “Test Pressure”?

The Rated Pressure (e.g., 60MPa / 6,000m) is the safe Working Pressure for continuous operation. The Test Pressure is typically set higher (e.g., 1.5x or specific batch protocol) for a short duration during qualification to verify safety margins. HYSF tests every production batch to ensure zero leakage at the Rated Pressure.

Safety margins are critical in subsea engineering.

  • Working Pressure (SWP): 60MPa. This is the depth at which the connector is designed to operate 24/7.
  • Burst/Failure Pressure: The theoretical limit where structural failure occurs, which is significantly higher than 60MPa.
  • Our Protocol: We utilize 100MPa High-Pressure Pumps in our lab. Routine batch testing confirms seal integrity at the rated depth for 60 minutes to catch any infant mortality failures.
