Transition elbow 90° - female threaded - N - 28mm-Rp1" IVAR.IVN30

Product detailed description

This 90° transition elbow is a critical component in press and threaded piping systems where a change in direction is required. It is commonly used in residential and commercial buildings for heating, plumbing and industrial applications. Installers typically encounter this fitting in systems requiring both press and threaded connections, such as those involving high-pressure water circuits or chemical-resistant piping. The fitting ensures secure and leak-free transitions between press and threaded components, particularly in environments where corrosion resistance and long-term reliability are essential.

The elbow is suitable for a wide range of applications including fire suppression, solar thermal systems, compressed air lines and sanitary installations. Its stainless steel construction provides durability and resistance to aggressive media, making it ideal for both indoor and outdoor installations where exposure to moisture or chemicals is expected.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM sealing ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN30.2810
Brand	IVAR

The nominal pressure rating of PN 16 indicates the maximum pressure the fitting can withstand under standard operating conditions. The operating temperature range from -20 °C to +120 °C allows for use in both cold and hot water systems. These parameters are essential for proper sizing and system design, ensuring compatibility with other components and adherence to safety standards.

Installation and connection

To install the elbow, align the press end with the pipe and apply the appropriate pressing force using a certified tool. The threaded end should be cleaned and inspected for damage before tightening. The minimum expansion length must be achieved to ensure a secure connection. Common installation mistakes include insufficient pressing depth, incorrect thread alignment and failure to inspect the sealing ring for damage. Always verify the expansion indicator reaches the specified 54 mm mark to confirm a proper seal.

Compatibility and accessories

This elbow is compatible with press and threaded fittings of the same nominal size. It is designed for use with stainless steel pipes and should be paired with compatible press tools and sealing rings. No additional accessories are required for standard installation. Ensure all components are from the same system to maintain integrity and performance.

Technical background for designers

The elbow operates by creating a directional change in the piping system while maintaining a tight seal through the EPDM O-ring. The stainless steel 1.4404 material offers high corrosion resistance and mechanical strength, making it suitable for aggressive environments. The integration into the system depends on the hydraulic requirements, such as flow rate and pressure drop. Long-term efficiency is influenced by the quality of installation, including proper pressing and alignment, as well as the use of compatible materials.

Service and operation

Periodic inspection of the connection for leaks and wear is recommended, particularly in high-pressure or high-temperature applications. Check the sealing ring for signs of degradation and replace if necessary. Ensure the expansion indicator remains within the specified range during reinstallation. No specific service intervals are provided in the technical documentation; maintenance should be carried out according to system requirements and observed performance.

Frequently asked questions

Can this elbow be used in solar thermal systems?
Yes, it is suitable for solar thermal systems due to its high temperature resistance and corrosion-resistant stainless steel construction.

Is this elbow compatible with press tools from other manufacturers?
It should be used with certified press tools designed for the specific system to ensure a secure and leak-free connection.

What is the maximum allowable operating temperature?
