PRESS-GAS fire protection fitting - direct, 1" M x 32

Product detailed description

This fire protection fitting is used in industrial and commercial gas installations where the ALPEX-GAS pipe transitions from a structural component into internal piping. The device ensures safe operation in case of fire by isolating the gas supply. Installers working on gas distribution systems in buildings such as factories, warehouses and large residential complexes will find this fitting essential for maintaining code compliance and system integrity.

The fitting is commonly used in systems requiring fire-resistant gas shut-off solutions. It is installed at points where the gas line passes through walls or floors and continues within the building structure. The device must be correctly sized and positioned to ensure it functions effectively during emergency conditions.

Technical parameters

The nominal pressure rating PN 10 indicates the maximum allowable operating pressure under normal conditions. The operating temperature range from -20°C to +60°C determines the environmental limits for installation. These parameters are crucial for ensuring correct system sizing and compatibility with other components in the gas network.

Installation and connection

The fitting connects directly to an internal 1-inch male thread and to the 32 mm ALPEX-GAS pipe. The installation process requires cutting the pipe to size, preparing the ends, and crimping the fitting using approved tools. Installers must verify that the thread is clean and free of debris before tightening the connection to the recommended torque.

Common mistakes include improper crimping, which can lead to leaks, and incorrect alignment of the fitting with the pipe. After installation, a visual inspection should confirm that the connection is secure and that the sealing ring is properly seated. A pressure test at a reduced level can also be performed to detect potential faults early.

Compatibility and accessories

This fitting is designed for use with ALPEX-GAS piping systems. It requires compatible crimping tools and must be used in conjunction with standard internal threaded components. Additional fittings and valves should be selected based on the overall system design and local regulations.

Technical background for designers

The fitting operates by maintaining a sealed connection between the rigid piping and flexible ALPEX-GAS pipe. The galvanized steel body provides resistance to corrosion while the CW617N brass and HNBR seal ensure durability under varying temperatures. The device integrates into the gas network by acting as a fire barrier that prevents gas flow in high-temperature conditions.

The service life depends on proper installation, correct operating conditions and regular inspections. The material properties ensure long-term reliability in environments with moderate temperature fluctuations and low chemical exposure. The design allows for easy replacement if damage occurs during installation or operation.

Service and operation

No specific service intervals are defined for this component. However, periodic visual inspections are recommended to check for signs of wear, corrosion or leakage. If any issues are detected, the fitting should be replaced immediately to maintain system safety.

Frequently asked questions

Can this fitting be used with other pipe types besides ALPEX-GAS?
No, it is specifically designed for ALPEX-GAS piping and will not function correctly with other materials.

Is it possible to install this fitting in a vertical orientation?
Yes, the fitting can be installed vertically, horizontally or at an angle, depending on the system layout.

What tools are required for crimping this fitting?
Approved crimping tools compatible with ALPEX-GAS systems are required to ensure a secure connection.

Can this fitting be used in high-pressure gas systems?
It is rated for nominal pressure PN 10, so it is suitable for systems operating within this limit.
