Fire protection flange fitting-FIREBAG - DN 32; 4 holes IVAR.TASF

Product detailed description

Fire protection flange fittings are essential components in gas distribution systems installed in residential, commercial and industrial buildings. These fittings are typically used in gas supply lines to prevent the uncontrolled release of gas in the event of a fire. Installers working on gas infrastructure must ensure that all fire protection devices are correctly integrated into the system to meet safety regulations. The IVAR TASF03200 is designed for use in gas pipelines where fire safety is a critical requirement. It is commonly found in gas installations in kitchens, boiler rooms, and industrial gas processing areas.

Technical parameters

Material	Galvanised steel
Operating temperature	-20 °C
Nominal diameter	DN 32
Nominal pressure	PN 16
Weight	4.2 kg
Code	TASF03200
Brand	IVAR

The nominal diameter of DN 32 ensures compatibility with standard gas pipe sizes, while the PN 16 pressure rating indicates the maximum allowable operating pressure. The operating temperature range from -20°C to +60°C allows the fitting to function in a wide range of environmental conditions. These parameters are essential for proper sizing and selection to ensure the device performs reliably under expected operating conditions.

Installation and connection

The IVAR TASF03200 is installed using a flange connection according to DIN 2501 standards. The fitting has four holes for bolting to adjacent flanges. Installers must ensure that the flange surfaces are clean and free from debris before tightening the bolts to the recommended torque. The galvanised steel construction requires no additional corrosion protection, but the integrity of the flange seal must be verified during installation. Common installation errors include misalignment of the flange faces or over-tightening of bolts, which can damage the sealing surface.

Compatibility and accessories

This fire protection flange is compatible with standard gas piping systems using DN 32 pipes. It is intended for use with other fire safety components such as gas shut-off valves and pressure regulators. No additional accessories are required for basic installation, but sealing gaskets and bolts must be provided separately. The fitting is not interchangeable with non-fire-rated flanges and must be used in accordance with TPG 704 01 guidelines.

Technical background for designers

The IVAR TASF03200 operates by releasing a sealing element within the fitting when the ambient temperature reaches approximately +100°C. This action closes the gas supply to prevent the spread of flammable gas during a fire. The galvanised steel construction provides resistance to corrosion and mechanical stress. The device is designed to maintain structural integrity at temperatures up to +650°C for a minimum of 30 minutes. The integration of the fitting into the gas system must account for the thermal expansion of the piping and the need for secure flange alignment.

Service and operation

The device requires no regular maintenance under normal operating conditions. However, periodic inspections should be carried out to check for signs of corrosion, mechanical damage or misalignment. The integrity of the sealing element should be verified during routine safety checks. No specific service intervals are defined in the technical data, but the device should be replaced if any damage is detected.

Frequently asked questions

Can the IVAR TASF03200 be used in low-temperature environments?
Yes, the fitting is rated for operation down to -20°C, making it suitable for use in cold storage facilities and outdoor installations.

Is the IVAR TASF03200 compatible with other IVAR gas system components?
Yes, the fitting is designed for integration with IVAR gas piping systems and is compatible with standard DN 32 gas pipes and flanges.

What happens when the ambient temperature reaches +100°C?
At this temperature, the internal sealing element is released, which closes the gas supply to prevent the uncontrolled release of gas during a fire.

Can the IVAR TASF03200 be used in high-pressure gas systems?
Yes, the fitting is rated for a maximum operating pressure of PN 16, making it suitable for use in standard gas pressure ranges.
