Arch 90° - N - 18mm IVAR.IVN20

Product detailed description

This 90° elbow is commonly used in heating systems, plumbing networks, fire sprinkler systems and industrial installations where reliable and durable piping solutions are required. It is particularly suited for applications involving water, steam, air and inert gases. The component is ideal for use in residential, commercial and industrial buildings where press-fit stainless steel piping systems are specified. The installation requires precise alignment and pressing to ensure a leak-tight connection.

During installation, the elbow is pressed into position using a certified press tool. The pressing process must be carried out according to manufacturer guidelines to achieve a secure joint. The elbow is designed to integrate with other components in the same system, including straight pipes, tees and other fittings, ensuring a consistent and robust piping layout. It is important to verify the correct dimensions and alignment before pressing to avoid misalignment or damage to the fitting.

Technical parameters

Material	Stainless steel grade 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN20.18
Brand	IVAR

The elbow is rated for a nominal pressure of PN 16 and can operate within a temperature range from -20°C to +85°C, with a maximum of +120°C. These parameters are essential for selecting the correct component based on the system's operating conditions. The pressure rating ensures suitability for medium-pressure applications, while the temperature range allows for use in both cold and hot water systems.Installation and connection The elbow is connected using a press-fitting technique. Ensure that the pipe ends are clean and free from burrs before assembly. Align the elbow with the pipe axis and apply the press tool evenly around the joint until the pressing indicator reaches the specified dimension of 54 mm. After pressing, inspect the joint for even deformation and proper alignment. Common installation errors include insufficient pressing force, misalignment and use of non-certified tools, which can lead to leaks or reduced system performance.Compatibility and accessories This elbow is compatible with other stainless steel press-fit components from the same system, including straight pipes, tees and other elbows. For complete system assembly, ensure that all components are from the same manufacturer and specification. Additional components such as straight pipes and tees should be selected based on the system design and flow requirements.Technical background for designers The elbow is constructed from stainless steel grade 1.4404 (AISI 316L), known for its corrosion resistance and mechanical strength. The EPDM O-ring provides a flexible seal that compensates for minor misalignments and thermal expansion. When integrated into a system, the elbow contributes to the overall hydraulic balance and structural integrity. Long-term performance depends on proper installation, correct operating conditions and system maintenance. Avoid exposure to aggressive media beyond those specified in the manufacturer’s documentation.Service and operation No specific service intervals are required for this component. Regular visual inspections are recommended to detect signs of wear, corrosion or leakage. In case of suspected leaks, inspect the pressing joints and re-press if necessary. Ensure that the system is depressurized before carrying out any inspection or repair work. Maintain the system according to standard maintenance practices for stainless steel piping systems.Frequently asked questions

Can the IVN20.18 be used in solar heating systems?
Yes, the elbow is suitable for solar heating systems provided the operating conditions remain within the specified temperature and pressure limits.

Is it compatible with inert gas applications?
Yes, the elbow is approved for use with inert gases within the defined operating parameters.

What is the role of the pressing indicator during installation?
The pressing indicator ensures that the tooling has applied sufficient force to create a leak-tight joint. The indicator should reach the specified dimension of 54 mm during the pressing process.

Can this elbow be used in fire sprinkler systems?
Yes, the component is suitable for fire sprinkler systems as long as the system operates within the stated pressure and temperature ranges.
