Product catalog summary
Introduction
The document discusses the Chesterton® Manway Sealing System, designed to enhance the safety and reliability of steam drum manway doors. This system addresses the challenges of sealing in thermal cycles by focusing on selecting the appropriate gasket and maintaining gasket sealing stress.

Key Features
  • Safety and Reliability: The system reduces the need for hot retorque requirements, thereby improving plant safety and reliability by minimizing unscheduled downtime.
  • Maintenance Simplification: A standardized program simplifies maintenance requirements.

Chesterton Manway Sealing Solution
The solution includes live loading technology, which involves an in-plant survey and engineering review to select the proper gasket and improve sealing stress. This technology is suitable for applications with vibration, pressure surges, and thermal cycling.

Live Loading System
Ensures proper bolt load to maintain gasket performance and prevent leakage. It uses discs to maintain bolt loads and gasket seating stress above the minimum required.

Gasket Technologies
  • SteelTrap™ Manway Gaskets: Encapsulates graphite sealing elements within a stainless steel carrier, suitable for temperatures up to 650˚C (1200˚F) and pressures up to 415 bar g (6000 psig).
  • 459 Graphite Manway Gasket: A graphite sheet with nickel foil reinforcement for high-pressure, high-temperature applications, with excellent chemical resistance.
