Arch 45° - N - 18mm IVAR.IVN22

Product detailed description

45° elbows are essential components in the design and installation of heating, plumbing and technical piping systems. They are commonly used in residential, commercial and industrial buildings to create directional changes in piping layouts. In heating systems, these fittings help to route pipes around obstacles or to adjust the direction of flow in radiators, underfloor heating or boiler circuits. In technical installations, they are used in sprinkler systems, compressed air lines, solar systems and industrial gas lines. The IVAR IVN22.18 is designed for use in such applications, where reliable sealing and resistance to thermal and mechanical stress are required.

Correct selection of elbow fittings is crucial for system performance and longevity. The operating conditions, including temperature range and pressure, must be matched to the fitting’s specifications. In systems with fluctuating temperatures or high thermal expansion, the flexibility and sealing properties of the fitting become especially important. The IVAR IVN22.18 is designed to meet these demands, with a stainless steel body and EPDM sealing ring that provide long-term stability and resistance to common installation challenges.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), O-ring EPDM
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN22.18
Brand	IVAR

The operating temperature range of -20 °C to +120 °C allows the fitting to be used in both cold and hot water systems, as well as in heating circuits. The nominal pressure rating of PN 16 ensures compatibility with medium-pressure systems. These parameters are essential for determining the suitability of the fitting for a given application and for ensuring that the system remains leak-free and functional over time.

Installation and connection

The IVAR IVN22.18 is a press-fit elbow with one press connection and one socket end. The socket end allows for insertion of a pipe, which is then secured using a press tool. The press connection must be made according to the manufacturer’s instructions to ensure a tight seal. The elbow is designed for use with 18 mm nominal pipe size. During installation, it is important to ensure that the pipe is fully inserted into the socket and that the press tool is correctly aligned with the connection point. Common installation mistakes include insufficient insertion depth, incorrect press tool positioning and failure to check the alignment of the elbow with the surrounding piping. After installation, the connection should be inspected for any visible misalignment or damage.

Compatibility and accessories

The IVAR IVN22.18 is compatible with stainless steel pipes of 18 mm nominal size. It is designed for use with press-fit systems that use the same type of sealing ring and connection method. For complete system integration, it is necessary to use compatible press tools and accessories. No additional products are required for standard installation. The elbow is suitable for use in systems that require resistance to corrosion and thermal expansion, such as those found in heating, plumbing and industrial applications.

Technical background for designers

The IVAR IVN22.18 is a 45° elbow made from 1.4404 (AISI 316L) stainless steel, a material known for its high corrosion resistance and mechanical strength. The EPDM O-ring provides a flexible seal that compensates for minor misalignments and thermal expansion. The elbow is designed to be integrated into press-fit systems, where the connection is made using a press tool that compresses the fitting around the pipe. The operating principle relies on the tight fit between the pipe and the fitting, ensuring a leak-free connection. The choice of stainless steel ensures long-term durability in environments with fluctuating temperatures and chemical exposure. The elbow is suitable for use in a wide range of systems, including those with high thermal expansion or where airtightness is critical.

Service and operation

The IVAR IVN22.18 requires no regular maintenance under normal operating conditions. However, it is important to periodically inspect the connections for signs of leakage or damage, especially in systems with high thermal cycling. If a leak is detected, the connection should be checked for proper insertion and press-fit integrity. The fitting is designed for long-term use and does not require scheduled service intervals. In the event of a failure, the elbow should be replaced with a new fitting of the same type and size.

Frequently asked questions

Can the IVAR IVN22.18 be used in solar heating systems?
Yes, the elbow is suitable for use in solar heating systems due to its resistance to thermal expansion and its operating temperature range of up to +120 °C.

Is the IVAR IVN22.18 compatible with press tools from other manufacturers?
Compatibility depends on the specific press tool and its ability to match the dimensions and requirements of the fitting. It is recommended to use the manufacturer-recommended tools to ensure a secure connection.

Can the IVAR IVN22.18 be used in compressed air systems?
Yes, the elbow is suitable for use in compressed air systems, provided that the operating pressure and temperature are within the specified limits of PN 16 and -20 °C to +120 °C.

What is the maximum allowable temperature for the IVAR IVN22.18?
The maximum allowable temperature is +120 °C, beyond which the fitting may lose its sealing properties and structural integrity.
