Arch 45° PRESS GAS - 28mm IVAR.IVN22 GAS

Product detailed description

Gas distribution systems in residential, commercial and industrial buildings require reliable fittings that maintain integrity under varying conditions. This 45° press elbow is commonly used in gas supply lines for natural gas, biogas and liquid propane. Installers working on gas networks will find this fitting suitable for applications where directional change is required while maintaining system safety and efficiency.

The design allows for secure press connections, ensuring leak-free performance in gas piping systems. The elbow is intended for use in systems where directional changes are necessary, particularly in tight spaces where a 90° bend would be impractical. It is suitable for both new installations and system modifications, where flexibility and precision are required.

Technical parameters

Material	Stainless steel Wst. Nr. 1.4404 (AISI 316L), sealing O-ring HNBR yellow
Operating temperature	-20 °C
Nominal pressure	PN 5
Code	IVNGAS22.28
Brand	IVAR

The nominal pressure rating of PN5 indicates the fitting is suitable for low-pressure gas systems. The operating temperature range from -20°C to +70°C ensures functionality in environments with seasonal temperature variations. These parameters are critical for proper system sizing and compatibility with existing gas infrastructure.

Installation and connection

The fitting connects via press technology using compatible 28mm pipes. The connection requires a press tool calibrated for the specified pipe size. Installers should ensure the pipe end is clean and free of burrs before insertion. The sealing ring must be correctly seated in the groove to prevent misalignment during pressing. Common errors include over-pressing, which can damage the sealing ring, and under-pressing, which compromises the joint’s integrity. After installation, the joint should be visually inspected for even compression marks around the circumference.

Compatibility and accessories

This elbow is compatible with other IVAR.IVN22 GAS series components, including straight pipes and other press fittings. For larger diameters (76.1mm, 88.9mm and 108mm), the fitting is available upon special order. No additional accessories are required for standard installation, though system-specific tools may be necessary depending on the installation environment.

Technical background for designers

The elbow functions as a directional component in press-fit gas systems. The stainless steel construction offers resistance to corrosion and ensures long-term durability in gas environments. The HNBR sealing ring provides flexibility and maintains a tight seal under thermal expansion and contraction. The choice of material and sealing technology is essential for system longevity and safety. Designers should consider the elbow’s nominal pressure and temperature range when integrating it into larger gas distribution systems, particularly where multiple directional changes are required.

Service and operation

No regular maintenance is required for this fitting during normal operation. However, periodic visual inspections are recommended to check for signs of mechanical stress or deformation. The integrity of the press joint should be verified during routine system checks. If the fitting is suspected of failure, it should be replaced immediately to avoid potential gas leaks.

Frequently asked questions

Can this elbow be used with biogas systems?
Yes, the fitting is approved for use with biogas and meets the necessary requirements for gas distribution systems.

Is the sealing ring replaceable after installation?
No, the sealing ring is integrated into the fitting and cannot be replaced separately after the press connection is made.

What is the maximum allowable temperature during installation?
The fitting should be installed at ambient temperatures within the operating range of -20°C to +70°C to ensure proper sealing and joint integrity.

Can this elbow be used with non-IVAR press pipes?
It is recommended to use only IVAR press pipes to ensure compatibility and maintain the integrity of the press connection.
