Arch 45° - N - 28mm IVAR.IVN22

Product detailed description

This 45° stainless steel press elbow is commonly used in residential and commercial buildings for directional changes in heating and plumbing circuits. It is frequently found in closed-loop systems such as underfloor heating, domestic hot water supply, and fire suppression systems. The component is designed for use in environments where corrosion resistance and long-term reliability are essential. Installers working on HVAC systems, solar thermal installations, or industrial piping applications will find this fitting suitable for its material grade and pressure rating.

During installation, the fitting is pressed using a certified tool to ensure a leak-free seal. The EPDM sealing ring provides a flexible yet durable connection between the pipe and the fitting. The elbow’s stainless steel body ensures compatibility with aggressive media and high-temperature conditions typical in central heating and industrial applications.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM sealing ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN22.28
Brand	IVAR

The operating temperature range of -20°C to +85°C with a maximum of +120°C allows for use in both cold and hot water systems, as well as steam applications within defined limits. The nominal pressure rating of PN 16 ensures suitability for medium-pressure systems. These parameters are crucial for selecting the correct fitting for a given application and verifying compatibility with system design specifications.

Installation and connection

To install the Arch 45° press elbow, first ensure the pipe ends are clean and free from burrs. The fitting is slid over the pipe until the stop mark is reached. A certified press tool is then used to compress the fitting around the pipe, ensuring the indicator reaches the specified dimension. After pressing, verify the indicator position and recheck the alignment of the elbow. Common installation errors include insufficient pressing depth, misalignment, or using non-certified tools, which can compromise the integrity of the connection.

Compatibility and accessories

This press elbow is compatible with other IVAR press fittings and stainless steel pipes of the same diameter. For complete system integration, additional components such as straight couplings, unions, or valves may be required. Always refer to the manufacturer’s technical documentation for recommended combinations and system layouts.

Technical background for designers

The 45° elbow operates by redirecting fluid flow through a controlled angular bend, reducing turbulence compared to sharper bends. The use of 1.4404 stainless steel ensures high corrosion resistance and mechanical strength, making it ideal for long-term exposure to aggressive media. The EPDM sealing ring ensures a tight connection under pressure while maintaining flexibility. Designers should consider the elbow’s nominal pressure and temperature limits when planning system layouts and material selections.

Service and operation

Routine checks should include visual inspection of the press marks and the integrity of the connection. No scheduled maintenance is required unless leaks or system anomalies are observed. In the event of suspected failure, the entire section should be isolated and inspected using appropriate diagnostic tools.

Frequently asked questions

Can the Arch 45° press elbow be used in solar thermal systems?
Yes, the elbow is suitable for solar thermal systems due to its resistance to high temperatures and compatibility with closed-loop circuits.

Is the EPDM sealing ring compatible with all fluids?
The EPDM sealing ring is suitable for most water-based and inert gas applications but should not be used with aggressive chemical media outside the manufacturer's guidelines.

Can the elbow be used in fire suppression systems?
Yes, the elbow meets the requirements for use in sprinkler and fire suppression systems due to its pressure and temperature capabilities.

Can the elbow be reused after removal?
No, once the elbow has been pressed and removed, it must be discarded and replaced with a new fitting to ensure a secure connection.
