A CONTEMPORARY GUIDE TO MECHANICAL SEAL LEAKAGE

on physical phenomena and mathematical behavior of face seal dynamics. Mechanical seals rely on thin film lubrication in order to support axial loads in a low-friction regime at a film thickness that limits leakage as much as possible. Many sources derive the relationship that governs this effect for face seals (Lebeck, 1991; Panton, 1996).

Carbon Seal - an overview | ScienceDirect Topics

The life of carbon seals (radial and face seal) is significantly reduced in dry gas applications where the N 2 dew points are below −30°C (−22°F). Lessons Learned. The use of 'bone dry' N 2 (dew points below −30°C) for intermediate and separation sealing duties has resulted in low seal MTBFs (below 12 months).
