Faced 45° arc - N - 76,1mm IVAR.IVN73

Product detailed description

Stainless steel elbows are essential components in the installation of heating, sanitary and industrial piping systems. These fittings are used in residential and commercial buildings, including systems for hot and cold water distribution, heating circuits, fire suppression and industrial gas lines. The 45° angle allows for directional changes in tight spaces while maintaining smooth flow characteristics. The IVAR IVN73.76 is specifically designed for press-fit installation, ensuring a secure and leak-free connection when properly seated. It is commonly used in systems where corrosion resistance and long-term durability are critical.

Correct selection and installation of such fittings are crucial to system performance. The elbow must be compatible with the pipe diameter and system pressure to avoid leaks or failures. Installers must ensure that the fitting is fully seated and that the press-fit indicator is engaged to the specified dimension. This ensures a reliable seal and structural integrity of the connection.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L)
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN73.76
Brand	IVAR

The technical parameters define the operating limits and material properties of the fitting. The nominal pressure rating of PN 16 indicates the maximum pressure the fitting can withstand at standard operating temperatures. The temperature range from -20°C to +85°C with a maximum of +120°C defines the conditions under which the fitting remains functional and structurally sound. The material, 1.4404 (AISI 316L) stainless steel, is selected for its high corrosion resistance and mechanical strength, making it suitable for a wide range of media and environments.

Installation and connection

The IVAR IVN73.76 is installed using a press-fit method. The elbow is placed over the prepared pipe end and secured using a compatible pressing tool. The press-fit indicator must be engaged to the specified 54 mm dimension to ensure a secure connection. The fitting features an internal thread (22 mm-Rp3/4") for compatibility with threaded components. During installation, it is important to check that the pipe end is clean and free from burrs. A common mistake is insufficient pressing, which can lead to leaks or failure under pressure. Installers should also verify that the fitting is correctly aligned and that the press-fit tool is properly calibrated for the fitting size.

Compatibility and accessories

The IVAR IVN73.76 is compatible with standard stainless steel piping systems that use press-fit connections. It is designed to work with pipes of the same material and diameter. For threaded connections, the internal Rp3/4" thread allows for integration with other threaded components. No additional accessories are required for standard installation, but a compatible pressing tool is essential for correct assembly. The fitting is suitable for use in systems with inert gases, hot water, and industrial media as specified in the manufacturer's documentation.

Technical background for designers

The 45° elbow functions by redirecting the flow of media within the piping system. The stainless steel construction ensures resistance to corrosion and mechanical stress, making it suitable for long-term use in aggressive environments. The press-fit connection relies on a mechanical deformation of the fitting to create a tight seal. The material's properties, including its high tensile strength and resistance to thermal expansion, ensure that the fitting maintains its integrity under varying operating conditions. The elbow is designed to integrate seamlessly into systems with nominal pressure ratings up to PN 16. The service life and efficiency of the fitting depend on correct installation, proper alignment and the absence of mechanical stress from misalignment or over-tightening.

Service and operation

The IVAR IVN73.76 requires no regular maintenance under normal operating conditions. However, periodic visual inspections are recommended to check for signs of wear, corrosion or mechanical stress. If the fitting is suspected of being compromised, it should be replaced immediately. No specific service intervals are provided in the technical documentation, but the fitting should be replaced if it shows signs of leakage or structural damage. The press-fit indicator should be checked during installation to ensure that the fitting is correctly seated and that the connection is secure.
