Faced arc 15° - N - 22mm IVAR.IVN75

Product detailed description

The IVN75.22 15° faced arc is a precision component used in stainless steel press-fit systems for heating, plumbing, and industrial applications. It is commonly installed in systems requiring directional changes in pipe routing, such as in underfloor heating layouts, industrial gas lines, or pressurised water circuits. The 15° angle allows for fine adjustments in alignment, particularly useful in tight spaces or where minimal flow disruption is required. Installers working on systems with tight tolerances or complex geometries will find this component suitable for maintaining hydraulic efficiency and structural integrity.

Its stainless steel construction ensures compatibility with a range of fluids and gases, including potable water, inert gases, and solar system media. The component is suitable for use in both residential and commercial environments, including industrial facilities where corrosion resistance and durability are critical. It is often used in conjunction with other press-fit fittings to create leak-tight connections without the need for welding or threading.

Technical parameters

Material	stainless steel grade Wst. Nr. 1.4404 (AISI 316L)
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN75.22
Brand	IVAR

The PN 16 rating indicates the component is suitable for systems operating at a nominal pressure of 16 bar. The operating temperature range from -20°C to +120°C allows for use in both cold and hot applications, including heating and solar systems. These parameters are essential for ensuring correct sizing and compatibility with the system’s design pressure and temperature conditions.

Installation and connection

The IVN75.22 is installed using a press-fit tool to compress the fitting around the pipe. The pipe must be cut cleanly and deburred to ensure a proper fit. The connection size is 22mm nominal, with external threading for compatibility with other threaded components. During installation, the installer must verify the correct depth of insertion and ensure the press tool is properly aligned with the fitting. Common installation errors include misalignment of the press tool, which can lead to incomplete compression, or failure to check for burrs on the pipe end, which can compromise the seal.

Compatibility and accessories

This 15° faced arc is compatible with other IVAR press-fit components in the IVN70, IVN73, IVN74, and IVN75 series. It is typically used in conjunction with straight pipes, elbows, and tees of the same nominal size. For systems requiring threaded connections, the external threading allows for integration with standard R1/2" components. No additional accessories are required for standard installation, but a press tool and suitable dies are necessary for the press-fit process.

Technical background for designers

The 15° faced arc operates by redirecting the flow of media through a controlled angular change. The use of 1.4404 (AISI 316L) stainless steel ensures high corrosion resistance and mechanical strength, making it suitable for aggressive environments. The press-fit system eliminates the need for welding, reducing installation time and potential for leaks. The material’s properties also contribute to long-term durability and minimal maintenance requirements. The angle of the arc is designed to reduce turbulence and pressure loss, making it ideal for applications where flow efficiency is important.

Service and operation

The component requires no regular maintenance under normal operating conditions. However, during routine inspections, installers should check for signs of mechanical stress or corrosion, particularly at the press-fit connection. If the system is exposed to high temperatures or aggressive media, additional monitoring may be necessary. There are no specified service intervals for this component under standard conditions.
