Next-Gen Sealing Tech for Volatile Pipelines

John Crane has unveiled the Type 8628VL, a breakthrough mechanical seal designed to withstand the extreme demands of multiphase ethane and ethylene pipelines, where fluid can rapidly shift between liquid, vapour, and supercritical states.

By leveraging spiral groove non-contacting technology, the 8628VL offers:

• Superior phase-change resilience
• Zero-wear operation
• Reliable sealing under volatile pressure & temperature

A leading US Gulf Coast operator reported zero failures and minimal leakage after months of continuous use. This innovation not only boosts uptime and performance but also cuts refurbishment costs and enhances environmental compliance.
