Arch 90° - N - 35mm IVAR.IVN20

Product detailed description

The IVAR IVN20.35 90° elbow is a critical component in press-fit stainless steel piping systems used in professional heating, plumbing and industrial applications. It is commonly installed in closed-loop systems such as underfloor heating, solar thermal circuits, and industrial process lines where resistance to corrosion and high temperatures is essential. The fitting is designed for use in environments where the system media may include water, steam, inert gases or non-aggressive chemical solutions. The elbow is typically used in conjunction with straight pipe sections and other press-fit fittings to create directional changes in the piping layout without the need for welding or threading.

Its compact design and precise geometry allow for efficient space utilisation in tight installation areas such as mechanical rooms, underfloor cavities or within wall cavities. The elbow is suitable for both new installations and system retrofits where minimal disruption is required. It is particularly valued in applications where system integrity and long-term reliability are critical, such as in hospitals, commercial buildings and industrial facilities.

Technical parameters

Installation and connection

Installation of the IVN20.35 requires a press-fit tool compatible with the fitting’s dimensions. The elbow is connected to stainless steel pipes using a press tool that compresses the fitting around the pipe, creating a secure and leak-tight joint. The nominal pipe size is 35 mm, and the fitting is designed for use with pipes of the same size. It is important to ensure that the pipe is properly inserted into the fitting to the correct depth before pressing. A misalignment or incomplete insertion can lead to a weak joint and potential leaks. The press tool must be calibrated to the correct pressing force and depth to ensure a consistent and reliable connection. Common installation errors include using an incorrect press tool, failing to check the pipe insertion depth, or attempting to reuse a fitting after pressing.

Compatibility and accessories

This 90° elbow is compatible with other press-fit fittings and stainless steel pipes of the same nominal size. It is typically used in conjunction with straight pipe sections, T-joints and other elbows to create complex piping layouts. For system integrity, it is important to use press-fit tools and accessories from the same manufacturer to ensure compatibility and performance. No additional accessories are required for installation, but it is recommended to verify the compatibility of the press tool with the fitting before use.

Technical background for designers

The elbow operates by redirecting the flow of the system media through a 90° angle. The EPDM O-ring ensures a tight seal between the pipe and the fitting. The press-fit connection eliminates the need for welding or threading, reducing installation time and potential for human error. The system’s efficiency and service life depend on correct installation, proper alignment of components and adherence to the manufacturer’s technical specifications.

Service and operation

Once installed, the elbow requires minimal maintenance. Regular visual inspections should be conducted to check for signs of wear, corrosion or leakage. If the system is used in high-temperature or aggressive environments, more frequent inspections may be necessary. There are no scheduled service intervals for this component, but any signs of damage or degradation should be addressed immediately to prevent system failure.

Frequently asked questions

Can the IVN20.35 be used in solar thermal systems?
Yes, the elbow is suitable for solar thermal applications as it can handle temperatures up to +120°C and is compatible with press-fit stainless steel piping systems.

Is the elbow compatible with other IVAR press-fit fittings?
Yes, the IVN20.35 is designed to be used with other IVAR press-fit fittings and stainless steel pipes of the same nominal size.

Can the elbow be used in industrial gas applications?
Yes, the elbow is suitable for inert gas applications due to its stainless steel construction and EPDM sealing ring.

What is the maximum allowable temperature for this fitting?
The maximum allowable temperature is +120°C, beyond which the performance and integrity of the fitting may be compromised.
