The Henry Technologies 5526-450-CE Rupture Disc is a critical safety bypass component designed for high-pressure refrigeration systems and industrial pressure vessels. Built with a robust 1/2" MPT steel connection, ??? assembly features a precision-engineered nickel alloy foil disc that is domed against the direction of fluid pressure. This reverse-acting rupture disc design allows the component to buckle under compression forces before bursting, providing superior fatigue life and resistance to temperature fluctuations compared to forward-acting alternatives. Supporting a burst pressure of 450 PSI (31.0 barg), it is an essential secondary relief device often paired with Henry Technologies pressure relief valves to prevent refrigerant weeping and ensure ASME Section VIII Division 1 compliance.

Engineered for compatibility with HCFC, HFC, and CO2 refrigerant gases, the 5526-450-CE utilizes a non-fragmenting design to protect downstream piping and delicate system components from debris after a discharge event. Each unit is helium leak tested and CE marked, ensuring high flow capacity and operational reliability in temperatures ranging from -40°F to 300°F. For veteran contractors, this 1/2-inch MPT rupture disc provides a compact, tamper-proof solution for safeguarding receivers and heat exchangers against catastrophic overpressure caused by fire or system malfunction.

Key Benefits

• Reverse-acting architecture increases durability and reduces sensitivity to system pressure cycles.
• Non-fragmenting foil disc hinges upon rupture, maintaining a clear flow path without shedding metal into the line.
• 1/2" MPT steel body provides excellent corrosion resistance and high-torque mechanical strength for industrial environments.
• Precision-scored burst point maintains a +/- 5% tolerance for predictable safety performance at 450 PSI.
• Leak-proof construction allows for integration with pressure gauges to detect relief valve discharge immediately.

Common Questions

• What is the difference between the 55 and 56 series? The 55 series, like this 5526-450-CE, typically features a brass or steel construction suitable for standard HFC/HCFC/CO2 refrigerants, whereas the 56 series uses stainless steel specifically for ammonia applications.
• Can this disc be used for liquid over-pressure? No, these rupture discs are specifically designed for gas and vapor applications and should not be used to prevent liquid over-pressure.
• How often should these be replaced? For optimal system integrity, it is recommended to replace high-side rupture discs every 2 years and low-side discs every 5 years, or immediately following any discharge event.
