Faced arch 90° - N - 28mm IVAR.IVN70

Product detailed description

Stainless steel faced arches are essential components in press-fit systems for heating, sanitary, and industrial applications. These fittings are commonly used in residential and commercial buildings to create directional changes in piping systems. Installers working on heating circuits, fire suppression systems, and solar installations often rely on these components to ensure leak-free and durable connections. The IVAR IVN70.28 is specifically designed for use with press-fit stainless steel piping, where tight tolerances and high corrosion resistance are required.

When installing systems that require directional changes, faced arches like the IVN70.28 are used to maintain flow efficiency and system integrity. They are particularly suited for environments where exposure to aggressive media or high temperatures is expected. The press-fit design eliminates the need for welding or threading, reducing installation time and ensuring a secure, long-lasting connection.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L)
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN70.28
Brand	IVAR

The operating temperature range of -20°C to +120°C allows this fitting to be used in a wide range of environments, from cold water supply to heated systems. The PN 16 pressure rating ensures compatibility with standard press-fit stainless steel piping systems. These parameters are critical for correct sizing and selection, especially in systems where thermal expansion and pressure fluctuations are common.

Installation and connection

The IVN70.28 is installed using a press-fit tool that compresses the fitting around the pipe, creating a secure and leak-proof connection. The nominal size of 28 mm corresponds to a 15 mm internal diameter, with a 1/2 inch Rp thread for external connections. During installation, it is essential to ensure the pipe is cut cleanly and free of burrs. The press-fit tool must be correctly aligned to avoid misalignment or damage to the fitting. Common installation errors include using incorrect press tools or failing to check the press depth indicator, which can lead to incomplete compression and potential leaks.

Compatibility and accessories

This faced arch is compatible with standard stainless steel press-fit piping systems. It is typically used in conjunction with other IVAR press-fit fittings, such as straight connectors, elbows, and tees. For complete system integration, additional components such as pipe sections, valves, and pressure regulators may be required. Installers should ensure that all components are from the same press-fit system to maintain compatibility and system integrity.

Technical background for designers

The IVN70.28 is a 90° faced arch made from 1.4404 stainless steel, a material known for its high corrosion resistance and mechanical strength. This material is suitable for use in aggressive environments and is commonly used in sanitary, fire suppression, and solar systems. The press-fit design allows for quick and reliable installation without the need for additional sealing materials. The PN 16 rating ensures the fitting can withstand typical system pressures, while the temperature range of -20°C to +120°C allows for use in both cold and heated systems. The longevity of the fitting depends on proper installation and system design, including adequate support and expansion compensation.

Service and operation

The IVN70.28 requires minimal maintenance due to its robust stainless steel construction and press-fit design. No regular service intervals are required, but periodic visual inspections are recommended to check for signs of wear, corrosion, or mechanical damage. If the fitting is part of a system that experiences frequent pressure fluctuations or thermal cycling, additional checks may be necessary to ensure the integrity of the press-fit connection. Any signs of leakage or deformation should be addressed immediately to prevent system failure.
