Fire protection flange fitting-FIREBAG - DN 25; 4 holes IVAR.TASF

Product detailed description

Fire protection flange fittings are essential components in gas distribution systems where fire safety is a critical requirement. These fittings are typically installed in residential, commercial and industrial buildings where gas lines run through areas at risk of fire exposure. Installers and system designers use such fittings to ensure that gas supply is automatically cut off in the event of a fire, preventing further hazards. The IVAR TASF02500 is designed for integration into gas pipelines with a nominal diameter of DN 25, ensuring compatibility with standard flange connections according to DIN 2501.

Correct installation of fire protection fittings is crucial for system integrity. The fitting must be positioned in a way that allows it to respond quickly to temperature changes, ensuring the gas supply is interrupted before the fire spreads. This is particularly important in areas such as boiler rooms, utility areas and gas storage zones. The fitting is not intended for use in high-temperature environments beyond its rated tolerance and must be installed in accordance with relevant standards such as TPG 704 01.

The technical parameters of the IVAR TASF02500 define its suitability for specific applications. The nominal diameter of DN 25 ensures compatibility with standard gas pipe sizes, while the PN 16 pressure rating indicates the maximum allowable operating pressure. The operating temperature range of -20°C to +60°C ensures the fitting can function in a wide range of environmental conditions. The material, galvanised steel, provides corrosion resistance and structural integrity, making it suitable for both indoor and outdoor installations.

Installation and connection

Installation of the IVAR TASF02500 requires careful attention to flange alignment and sealing. The fitting is designed for flange connections according to DIN 2501, and must be secured using appropriate bolts and gaskets. The four-hole flange configuration allows for even distribution of load and secure fastening. Installers should verify that the flange surfaces are clean and free of debris before tightening the bolts to the manufacturer’s recommended torque. Common installation errors include misalignment of flange faces, use of incorrect gasket materials and failure to check for proper sealing after installation.

Compatibility and accessories

The IVAR TASF02500 is compatible with standard DN 25 gas piping systems and can be integrated with other IVAR gas fittings and valves. For complete system functionality, it may be necessary to order additional components such as gaskets, bolts and sealing compounds. Installers should ensure that all accessories are compatible with the operating conditions and pressure ratings of the system. No specific related products are recommended for this model.

Technical background for designers

The IVAR TASF02500 operates on a thermal release mechanism. When the ambient temperature reaches approximately +100°C, a fusible element within the fitting body melts, triggering the closure of the gas supply. This prevents the spread of gas during a fire, reducing the risk of explosion or further combustion. The galvanised steel construction provides durability and resistance to corrosion, ensuring long-term performance. The fitting is designed to integrate seamlessly into gas distribution systems, with its flange connection allowing for easy installation and maintenance. The service life and efficiency of the fitting depend on correct installation, regular inspection and adherence to operating conditions specified by the manufacturer.

Service and operation

Regular inspection of the IVAR TASF02500 is recommended to ensure it remains in working condition. Installers should check for signs of corrosion, mechanical damage or improper sealing. The fitting does not require routine maintenance, but any visible damage or deformation should be addressed immediately. There are no specified service intervals for this model, and no internal components are designed for periodic replacement. In the event of a fire, the fitting will automatically activate and must be replaced after use.

Frequently asked questions

Can the IVAR TASF02500 be used in high-temperature environments?
No, the fitting is rated for a maximum operating temperature of +60°C. Exceeding this may affect its performance and integrity.

Is the IVAR TASF02500 compatible with other IVAR gas fittings?
Yes, it is designed to integrate with other IVAR components in DN 25 gas systems.

How does the fire protection mechanism activate?
When the ambient temperature reaches approximately +100°C, a fusible element melts and triggers the closure of the gas supply.

Can the IVAR TASF02500 be manually opened after activation?
No, once activated, the fitting must be replaced as it is not designed for reuse.
