Transition elbow 90° - male thread - N - 54mm-R2" IVAR.IVN31

Product detailed description

This 90° transition elbow is commonly used in residential and commercial buildings to connect press-fit stainless steel pipe systems with threaded components. It is suitable for a wide range of applications such as hot water supply, heating circuits, fire sprinkler systems, compressed air lines and industrial gas distribution. The elbow allows for secure and leak-free transitions between different connection types, ensuring system integrity under varying thermal and mechanical loads. Installers often use it in conjunction with stainless steel piping systems where flexibility between press and threaded fittings is required.

Correct installation ensures long-term performance and prevents leaks. The elbow is designed for use in environments with fluctuating temperatures and pressures, making it suitable for both indoor and outdoor installations provided thermal expansion is accounted for. Its robust construction supports integration into closed-loop systems and allows for easy maintenance when necessary.

Technical parameters

Material	Stainless steel grade 1.4404 (AISI 316L), EPDM sealing ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN31.5420
Brand	IVAR

The elbow is rated for a nominal pressure of PN 16 and can operate continuously within a temperature range of -20 °C to +85 °C, with short-term exposure up to +120 °C. These parameters are essential for selecting the correct component based on the system's operating conditions. The material grade and sealing ring type also influence compatibility with different fluids and gases. The specified temperature range ensures the EPDM seal remains effective under normal and transient thermal loads.

Installation and connection

The elbow features a male thread on one end and a press-fit connection on the other. Before installation, ensure the press-fit side is correctly sized to match the 54 mm pipe diameter and that the thread matches the mating component. Use a suitable pressing tool to compress the fitting according to the manufacturer's specifications. Always verify that the seating surface is clean and free from debris before tightening the threaded connection. Common errors include over-tightening the thread, which can damage the sealing surface, and improper pressing depth, which can compromise the seal. Check the alignment of the elbow to avoid stress on the pipe joints.

Compatibility and accessories

This elbow is compatible with press-fit stainless steel piping systems using 54 mm nominal diameter. It is intended for use with IVAR press fittings and stainless steel pipes of the same class. When installing, ensure that all adjacent components are also rated for the same pressure and temperature range. Additional accessories such as sealing rings and pressing tools should be sourced separately. Related products include press fittings, straight couplings and threaded adapters from the IVAR range.

Technical background for designers

The elbow functions as a directional change in the piping system, redirecting flow at 90°. The use of 1.4404 stainless steel provides high corrosion resistance, making it suitable for aggressive media and long-term exposure to moisture. The EPDM sealing ring ensures a tight connection under pressure and temperature fluctuations. The elbow is designed to integrate seamlessly with other press-fit components, maintaining system integrity. System longevity depends on proper installation, correct pressure and temperature management, and avoiding mechanical stress on the joints.

Service and operation

Routine inspection is recommended to ensure the integrity of the connection. Check for signs of leakage, especially after initial commissioning or following significant temperature changes. Verify that the press mark is fully engaged and that the thread is not over-tightened. No regular maintenance is required beyond visual checks unless the system is exposed to particularly harsh conditions. Replace the sealing ring if any degradation is observed.
