Faced 45° arc - N - 88,9mm IVAR.IVN73

Product detailed description

45° faced elbows are essential components in the installation of heating, plumbing and industrial systems. These fittings are commonly used in residential and commercial buildings to change the direction of flow in piping systems. Installers often work with these fittings in applications such as sanitary installations, fire sprinkler systems, heating systems and industrial gas lines. The IVAR IVN73.89 is designed for use in press-fit systems, where accurate alignment and secure connections are critical to system performance and safety.

When installing press-fit systems, it is important to ensure that the elbow is correctly sized and positioned to avoid stress on the piping. The 45° angle allows for gradual directional changes, reducing turbulence and pressure loss. This is particularly important in systems where flow efficiency and noise reduction are key considerations.

Technical parameters

Installation and connection

The IVN73.89 is designed for press-fit installation, which requires the use of a dedicated pressing tool and die set. The fitting must be inserted into the pipe and then compressed to form a secure, leak-tight connection. The internal thread allows for the connection of threaded components. During installation, it is important to verify that the pressing tool is correctly aligned and that the indicator mark reaches the specified dimension of 54 mm. Common installation errors include incorrect pressing depth, misalignment and the use of incompatible tools, which can lead to leaks or system failure.

Compatibility and accessories

This 45° faced elbow is compatible with other press-fit components from the IVAR IVN70, IVN73, IVN74 and IVN75 series. For a complete installation, it is recommended to use the appropriate pressing tool and die set. Additional components such as straight pipes, other elbows and tees may also be required, depending on the system layout and design specifications.

Technical background for designers

This material is particularly suitable for applications involving aggressive media or high temperatures. The press-fit connection ensures a reliable and durable joint without the need for additional sealing materials. The 45° angle allows for smooth directional changes in the piping system, reducing flow resistance and energy consumption. The design and material properties of the fitting contribute to its long service life and efficient performance in a wide range of environments.

Service and operation

During operation, it is important to periodically check the integrity of the press-fit connection. Any signs of leakage or deformation should be addressed immediately. The fitting does not require regular maintenance, but it is recommended to inspect the system during routine service checks. The absence of moving parts or seals means that the fitting is generally low-maintenance and reliable over its service life.
