Fire protection flange fitting-FIREBAG - DN 50 4 holes IVAR.TASF

Product detailed description

Gas pipeline systems in commercial and industrial buildings require critical safety components to prevent hazardous situations. Fire protection flange fittings are essential in such environments, particularly in gas distribution lines where a fire could cause catastrophic failures. These fittings are typically installed in boiler rooms, utility areas, and gas distribution points. Installers must ensure that all connections are secure and compatible with the system’s pressure and temperature requirements.

This fire protection flange fitting is part of a passive fire safety strategy. It is used in systems where gas supply interruption during a fire is necessary to prevent further risk. The component is designed to integrate seamlessly into standard gas piping layouts and is commonly found in heating, ventilation, and industrial gas applications. It is suitable for both new installations and retrofitting in existing infrastructure.

Technical parameters

Installation and connection

Installation requires precise alignment of the flange with the connected piping. The four-hole design allows for secure bolting using standard bolts and nuts. The fitting must be positioned in a location accessible for inspection and maintenance. Before tightening the bolts, verify that the sealing surface is free from debris and undamaged. Common mistakes include misalignment of the flange faces, which can compromise the seal, and over-tightening, which may damage the threads or the body of the fitting.

Compatibility and accessories

This flange fitting is compatible with standard gas piping systems using DN 50 connections. It is typically used with gas pipes made of steel or other approved materials. For installation, standard bolts, nuts, and sealing washers are required. Additional components such as support brackets or expansion joints may be needed depending on the system layout and thermal expansion characteristics of the piping.

Technical background for designers

The fire protection function is activated when ambient temperature reaches approximately +100 °C, within a tolerance of -5 K. At this point, a release element inside the fitting is triggered, closing the gas supply to prevent further flow. The galvanized steel construction provides corrosion resistance and structural integrity. When designing systems, consider the positioning of the fitting relative to potential fire sources and the thermal response time of the activation mechanism. The system’s overall efficiency depends on proper placement and compatibility with other components.

Service and operation

Periodic visual inspections are recommended to check for signs of wear, corrosion, or mechanical damage. Ensure that the flange remains aligned with the connected piping and that the sealing surfaces remain intact. No regular maintenance is required beyond these checks. If the fitting has been exposed to high temperatures or has triggered during a fire, it should be replaced according to the manufacturer’s guidelines.

Frequently asked questions

Can this fitting be used in high-temperature environments?
Yes, the fitting is designed to withstand temperatures up to +650 °C for 30 minutes. However, it is not intended for continuous operation at elevated temperatures outside its normal operating range.

Is the fitting compatible with other IVAR gas components?
Yes, it is designed for use with standard IVAR gas piping systems. Ensure that all components have matching nominal diameters and pressure ratings.

How is the fire protection mechanism triggered?
The mechanism activates when the ambient temperature reaches approximately +100 °C. At this point, an internal element releases, sealing the gas supply path to prevent leakage.

What should be checked after installation?
After installation, verify that the flange is properly aligned, the sealing surface is undamaged, and all bolts are tightened to the specified torque. Also confirm that the fitting is positioned in an accessible location for future inspection.
