Arch 45° FF, 28 x 28

Product detailed description

Press-fit elbows like the IVAR IVC22.28 are commonly used in central heating, fire suppression, and industrial fluid systems. They allow for directional changes in piping without the need for welding or threading, which is particularly useful in tight spaces or where rapid assembly is required. Installers working in residential, commercial, and industrial buildings often use these components in closed-loop systems, such as those found in underfloor heating, solar thermal installations, and air-conditioning ducts. The elbow is suitable for systems operating with water, inert gases, and dry air, but not for potable water applications.

These fittings are especially useful in environments where high-pressure resistance is required, such as in fire suppression systems or industrial cooling circuits. The compact design and lightweight nature of the component make it ideal for installations where access is limited or where aesthetics are a concern. The press-fit system ensures a secure connection without the need for additional tools or sealants, reducing installation time and potential for leaks.

Technical parameters

The operating temperature range of -20°C to +120°C allows the fitting to be used in both cold and hot environments. The PN16 rating means it can withstand pressures up to 16 bar, making it suitable for high-pressure systems. These parameters are essential for determining compatibility with the system's operating conditions and for ensuring correct sizing during design and installation.

Installation and connection

Installation of the IVAR IVC22.28 requires the use of press tools compatible with Type M jaws. The fitting is connected using a press method, which forms a secure joint without the need for welding or threading. The connection size is 28 x 28, and the installer must ensure that the mating ends are clean and free from debris before pressing. A molding indicator is present to confirm that the press operation has been completed correctly.

Common installation mistakes include using incompatible press tools or failing to align the components properly before pressing. This can result in an incomplete joint or a weakened connection. After installation, the system should be tested for leaks, and the molding indicator should be visually checked to confirm that the press operation was successful.

Compatibility and accessories

This 45° elbow is compatible with other IVAR press-fit components of the same size and material. It is designed to work with carbon galvanized steel pipes and requires no additional sealing materials. When assembling a system, it is important to ensure that all fittings and pipes are from the same manufacturer and system type to avoid compatibility issues. No additional surface coatings or limiting agents are required for the connection.

Technical background for designers

The IVAR IVC22.28 is made from carbon galvanized steel, which provides good resistance to corrosion and mechanical damage. The EPDM O-ring ensures a tight seal and is resistant to a wide range of temperatures and media. The press-fit system allows for quick and secure assembly, eliminating the need for welding or threading. This makes it ideal for use in systems where rapid installation is required, such as in retrofit projects or temporary installations.

The operating principle is based on the deformation of the pipe wall during the pressing process, which creates a mechanical and hydraulic seal. The material properties of the steel and the EPDM O-ring contribute to the long-term durability and performance of the fitting. The system's efficiency is also influenced by the correct selection of components and adherence to installation guidelines.

Service and operation

Once installed, the fitting requires minimal maintenance. Regular visual inspections should be carried out to check for signs of wear, corrosion, or damage. The system should also be tested periodically for leaks, especially after any modifications or repairs. No specific service intervals are provided, but it is recommended to follow the manufacturer's guidelines for system maintenance.
