PRESS-GAS fire protection fitting - corner, 3/4" M x 26

Product detailed description

This fire safety fitting is designed for integration into gas distribution systems where ALPEX-GAS piping transitions from an external to an internal installation. It is commonly used in residential and commercial buildings where gas supply lines pass through structural elements such as walls or ceilings. The fitting ensures a secure and fire-resistant connection between the flexible ALPEX-GAS pipe and rigid threaded components. Installers working on gas systems in new builds or renovations will find this fitting suitable for applications where the pipe route changes direction after exiting a structural barrier.

Such fittings are essential in maintaining the integrity of the gas supply and preventing leaks in the event of a fire. The operating temperature range and pressure ratings are critical for ensuring the fitting remains functional under normal and emergency conditions. The installation should be carried out in accordance with relevant technical standards to ensure system safety and compliance.

Technical parameters

The nominal pressure rating of PN 10 indicates the maximum pressure the fitting can handle under normal operating conditions. The operating temperature range from -20°C to +60°C ensures the fitting remains functional in a wide range of ambient conditions. These parameters are essential for correct sizing and selection to match the system's requirements and environmental conditions.

Installation and connection

Installation involves connecting the ALPEX-GAS pipe to the internal threaded connection using the corner fitting. The 3/4 inch male thread must be matched with a compatible female thread on the pipe or component. The installer should ensure the thread is clean and free of debris before tightening. A torque wrench may be required to achieve the correct tightening force without damaging the threads or seals.

Compatibility and accessories

This fitting is specifically designed for use with ALPEX-GAS piping systems. It requires a compatible internal threaded connection to complete the installation. No additional accessories are typically required for standard installations. Installers should verify that the system components are compatible with the fitting's material and pressure ratings to ensure long-term performance and safety.

Technical background for designers

The fitting operates as a fire safety device by maintaining a secure connection between the flexible and rigid parts of the gas system. The galvanized steel body provides corrosion resistance, while the brass components offer durability and compatibility with gas media. The HNBR sealing material ensures a tight seal under varying pressure and temperature conditions. The integration into the system depends on the correct alignment of the pipe and the threaded connection, ensuring no stress is applied to the fitting during operation. The service life is influenced by the quality of the installation, the operating conditions, and the maintenance of the system.

Service and operation

Regular inspection of the fitting is recommended to ensure the connection remains secure and leak-free. The installer should check for signs of corrosion, wear, or damage to the threads and sealing surfaces. No specific service intervals are provided in the technical data, but any signs of degradation should be addressed promptly. The fitting does not require routine maintenance under normal operating conditions.
