Arch 90° - with one socket end - N - 22mm IVAR.IVN21

Product detailed description

Stainless steel press fittings are essential components in modern heating, plumbing and sanitary systems. They are used in residential, commercial and industrial buildings for their durability and reliability. Installers and technicians often use these fittings in systems such as heating circuits, sprinkler systems, solar installations and industrial gas lines. The IVAR IVN21.22 90° elbow is specifically designed for applications requiring a single socket end connection, ensuring secure and leak-free joints in press-fitting systems.

When working with press fittings, it is important to understand the system requirements and the compatibility of components. This elbow is suitable for use in press systems where a 90° directional change is needed. It is commonly used in tight spaces or where a compact design is required. The fitting must be installed with care to ensure the correct press depth and alignment, which are critical for long-term performance.

Technical parameters

The technical parameters of the IVAR IVN21.22 are crucial for proper system design and component selection. The nominal pressure rating of PN 16 indicates the maximum pressure the fitting can handle under normal operating conditions. The operating temperature range from -20°C to +120°C ensures the fitting is suitable for both cold and hot media. These parameters are essential for determining the fitting's suitability for specific applications and for ensuring system integrity under varying conditions.

Installation and connection

Installation of the IVAR IVN21.22 90° elbow involves pressing the fitting onto the prepared pipe end using a certified press tool. The fitting has one socket end, which must be aligned with the pipe before pressing. The press depth must be checked using the manufacturer's indicator to ensure a secure connection. Common installation mistakes include incorrect alignment, insufficient press depth and using non-certified tools, which can lead to leaks or joint failure.

Before installation, the pipe must be cut cleanly and deburred. The O-ring must be inspected for damage and properly seated in the groove. The press tool must be calibrated and used according to the manufacturer's instructions. After pressing, the joint should be visually inspected for correct press depth and alignment. Any deviation from the specified press depth can compromise the integrity of the joint.

Compatibility and accessories

This 90° elbow is compatible with standard press-fitting systems using 1.4404 stainless steel pipes and fittings. It is designed to work with EPDM O-rings and must be used with press tools certified for this type of fitting. No additional accessories are required for standard installation. However, it is important to ensure that all components in the system are from the same manufacturer and are compatible with each other to avoid performance issues.

Technical background for designers

The IVAR IVN21.22 90° elbow is a directional fitting used to change the flow direction in a piping system. The EPDM O-ring provides a reliable seal against the media passing through the system. The press connection ensures a leak-free joint by compressing the O-ring between the pipe and the fitting. The material properties of stainless steel and the sealing mechanism of the O-ring are critical for the long-term performance of the fitting in various operating conditions.

When designing a system, it is important to consider the operating temperature and pressure, as well as the media being transported. The fitting's ability to withstand thermal expansion and contraction is a key factor in system reliability. Proper sizing and spacing of fittings are also important to prevent stress on the joints and ensure smooth flow through the system.

Service and operation

Once installed, the IVAR IVN21.22 requires minimal maintenance. The press joint is designed to be a permanent connection, and no regular service intervals are required. However, it is recommended to periodically inspect the joint for signs of wear, corrosion or leakage. If any issues are detected, the fitting should be replaced immediately to prevent system failure. The integrity of the joint can be checked by visually inspecting the press depth and alignment.
