Arc 90° - N - 88,9mm IVAR.IVN20

Product detailed description

This 90° stainless steel elbow is commonly used in residential and commercial heating systems, plumbing installations, and industrial applications where reliable, leak-free connections are essential. It is suitable for use in press-fitted stainless steel piping systems, particularly in environments requiring resistance to corrosion and high temperatures. Installers working on central heating, solar systems, or industrial piping will find this fitting ideal for creating directional changes in the piping layout without compromising system integrity.

Its design supports integration into press-fitted systems, where the fitting is joined to the pipe using a press tool and a sealing ring. The elbow is intended for use in press-to-press connections, ensuring a secure and durable joint. It is suitable for a range of applications including sanitary installations, fire sprinkler systems, and inert gas systems, where the operating conditions require resistance to both high and low temperatures.

Technical parameters

Installation and connection

Installation of the IVN20.89 requires a press tool compatible with the fitting's dimensions. The elbow is connected to stainless steel pipes using a press process that compresses the fitting around the pipe, creating a secure joint. The connection sizes are standard for press systems, and the installer must ensure that the pipe is correctly sized and prepared before pressing. A critical step is verifying the press depth indicator, which must align with the specified 54 mm mark to confirm a successful connection. Common installation errors include incorrect press depth, using a mismatched press tool, or failing to check the sealing ring for damage before installation.

Compatibility and accessories

This elbow is designed for use with stainless steel pipes of the same class and is compatible with press tools that support the specified dimensions. It is intended for press-to-press connections and is not suitable for use with other types of fittings such as soldered or threaded connections. For complete system integration, ensure that all fittings and pipes are from the same press-fitting system. No additional accessories are required for standard installation, but the sealing ring must be checked for integrity before use.

Technical background for designers

The elbow operates on the principle of mechanical compression, where the press tool forms a secure joint between the fitting and the pipe. The stainless steel material (Wst. Nr. The EPDM sealing ring ensures a tight seal and contributes to the longevity of the connection. The integration into the system depends on the overall design of the piping network, including the flow rate and pressure conditions. The service life of the fitting is influenced by the quality of the installation, the operating conditions, and the compatibility of the materials used in the system.

Service and operation

During operation, the elbow requires no regular maintenance. However, periodic inspections should be carried out to check for signs of wear, corrosion, or leakage. The integrity of the press joint should be visually inspected, and the sealing ring should be checked for any damage. If the joint shows signs of leakage, it must be replaced immediately. There are no specified service intervals for this fitting, as it is designed for long-term use under normal operating conditions.

Frequently asked questions

Can the IVN20.89 be used in solar heating systems?
Yes, the elbow is suitable for solar heating systems due to its operating temperature range and resistance to corrosion.

Is the elbow compatible with other press fittings from different manufacturers?
No, it is designed for use with press tools and pipes from the same system to ensure proper sealing and mechanical integrity.

What is the maximum allowable temperature for continuous operation?
The maximum continuous operating temperature is +85°C, with a short-term maximum of +120°C.

Can the elbow be used in industrial gas systems?
Yes, it is suitable for inert gas systems, provided the gas is non-corrosive and the operating conditions are within the specified parameters.
