Arch 90°, 108 x 108

Product detailed description

Long radius 90° elbows are essential components in pressurised piping systems for heating, industrial and fire protection applications. These fittings are used in closed systems where smooth flow transitions are required to reduce turbulence and pressure loss. Installers working in central heating, refrigeration, air-conditioning and solar systems frequently use these components to create safe, leak-free connections without the need for welding or threaded joints. The IVAR IVC70.108 model is designed for use in pressurised environments with a wide operating temperature range, making it suitable for both cold and hot applications.

When installing in industrial or commercial buildings, the elbow must be integrated into a system that maintains consistent pressure and flow. The use of press fittings ensures rapid assembly and eliminates the need for additional sealing materials. The elbow is particularly useful in systems where space is limited, as the long radius design allows for smoother directional changes compared to short radius alternatives. The galvanized steel construction provides resistance to corrosion and mechanical damage, ensuring long-term reliability in a variety of environments.

The operating temperature range of -20 °C to +120 °C makes this elbow suitable for both cold and hot systems, including heating and industrial applications. The PN 16 pressure rating indicates that the fitting is designed to withstand pressures up to 16 bar, which is essential for systems with high hydraulic demands. These parameters are critical for selecting the correct component for a given system, ensuring compatibility with the operating conditions and media being transported.

Installation and connection

The IVAR IVC70.108 is installed using a press tool compatible with Type M jaws. The elbow has a nominal size of 108 x 108 and is designed for direct connection to pipes of the same diameter. During installation, it is important to ensure that the molding indicator is fully engaged and that the press tool applies even pressure to both sides of the fitting. A common mistake is using an incorrect jaw type or applying insufficient pressure, which can result in a weak connection. Installers should also verify that the pipe ends are clean and free from burrs before pressing to ensure a secure and leak-free joint.

Compatibility and accessories

This elbow is compatible with other IVAR press fittings and pipes in the same size range. It is not certified for use with drinking water and should not be used in potable water systems. For larger systems, additional components such as straight pipes, tees and couplings may be required. Installers should also consider the need for expansion joints or supports in long runs to accommodate thermal expansion and contraction.

Technical background for designers

The elbow is constructed from carbon galvanized steel, which provides a balance of strength and corrosion resistance. The press fitting technology eliminates the need for welding or threading, reducing installation time and improving system integrity. The long radius design minimises flow resistance and pressure drop, making it suitable for systems where energy efficiency is a priority. The operating temperature range and pressure rating are key factors in system design, as they determine the suitability of the component for specific applications. The absence of surface coating limiting agents means that the elbow can be used in systems where chemical compatibility is a concern.

Service and operation

The elbow requires minimal maintenance due to its durable construction and press fitting design. There are no service intervals specified for this component, as it is intended for long-term use without disassembly. During operation, it is important to monitor for signs of mechanical damage or corrosion, particularly in environments with high humidity or chemical exposure. The absence of a surface coating means that the elbow may be more susceptible to environmental factors, so proper system design and installation are essential to ensure longevity.
