Fire protection flange fitting-FIREBAG - DN 40 4 holes IVAR.TASF

Product detailed description

Fire protection flange fittings are essential components in gas systems where fire safety is a critical requirement. These fittings are commonly installed in industrial and commercial buildings, particularly in areas where gas lines pass through fire-rated walls or partitions. The IVAR TASF04000 is designed for integration into such systems, ensuring that gas supply is automatically cut off in the event of a fire. This prevents the spread of flames and minimizes the risk of gas-related hazards. Installers working on gas distribution systems must ensure that these fittings are correctly positioned and connected to maintain system integrity and safety.

When installing in gas supply lines, the fitting must be positioned at points where fire barriers are present. This includes locations such as through-wall penetrations or under raised floors. The fitting is designed to remain functional under normal operating conditions but will activate when exposed to high temperatures, sealing the pipeline to prevent gas escape. This is particularly important in compliance with fire safety regulations for gas installations.

The technical parameters of the IVAR TASF04000 are crucial for correct sizing and selection. The nominal diameter of DN 40 ensures compatibility with standard gas pipelines of the same size. The operating pressure rating of PN 16 defines the maximum allowable working pressure for the fitting. The temperature range from -20°C to +60°C indicates the environmental conditions under which the fitting can be used. These parameters must be considered when designing gas systems to ensure that the fitting meets both operational and safety requirements.

Installation and connection

The IVAR TASF04000 is installed using a flange connection according to DIN 2501 standards. The fitting is equipped with four holes for bolting to adjacent flanges, ensuring a secure and leak-tight connection. The installer must verify that the flange surfaces are clean and free from debris before tightening the bolts. It is important to use the correct torque values for the bolts to avoid over-tightening or under-tightening, which can compromise the seal. A common mistake during installation is misalignment of the flanges, which can lead to uneven stress on the fitting and potential failure. To prevent this, the installer should use alignment tools and ensure that the flanges are parallel before tightening.

Compatibility and accessories

The IVAR TASF04000 is compatible with standard gas pipelines and flange systems designed for DN 40 connections. It is intended for use with galvanized steel flanges and must be connected using bolts and washers of the appropriate size and material. No additional accessories are required for basic installation, but it is recommended to use high-quality sealing materials to ensure a durable connection. There are no related products listed for this model, but installers should always refer to the manufacturer’s technical documentation for specific compatibility information.

Technical background for designers

The IVAR TASF04000 operates on a thermal release mechanism. When the ambient temperature reaches approximately +100°C (with a tolerance of -5 K), a release element within the fitting is triggered, causing the internal valve to close and block the gas flow. This mechanism is designed to activate quickly and reliably, ensuring that gas does not escape into the fire zone. The fitting is constructed from galvanized steel, which provides corrosion resistance and mechanical strength. The material is suitable for use in both indoor and outdoor environments, provided that the temperature and pressure conditions remain within the specified limits. The integration of the fitting into a gas system requires careful planning to ensure that it is positioned where it can effectively isolate the gas supply in the event of a fire.

Service and operation

Once installed, the IVAR TASF04000 requires minimal maintenance. There are no service intervals specified in the technical documentation, and the fitting is designed to remain functional without regular intervention. However, it is recommended to inspect the fitting during routine system checks to ensure that the flange connection remains secure and that there are no signs of corrosion or damage. If the fitting has been activated during a fire event, it must be replaced with a new unit, as the thermal release mechanism is a one-time-use component. The fitting should not be reactivated or repaired after activation.

Frequently asked questions

Can the IVAR TASF04000 be used in high-temperature environments?
The fitting is designed to withstand temperatures up to +650°C for 30 minutes during a fire, but it should not be used in environments where the normal operating temperature exceeds +60°C.

Is the IVAR TASF04000 compatible with other flange types?
The fitting is designed for use with flanges according to DIN 2501 and is not compatible with other flange standards without additional adapters or modifications.

Can the fitting be manually closed?
No, the IVAR TASF04000 is an automatic thermal release device and cannot be manually closed. It is designed to activate only when the ambient temperature reaches the specified threshold.

What happens after the fitting has been activated?
Once activated, the internal valve closes permanently. The fitting must be replaced with a new unit, as the thermal release mechanism is a one-time-use component.
