Faced arch 90° - N - 15mm IVAR.IVN70

Product detailed description

This 90° faced arch is commonly used in residential and commercial buildings for connecting pipes in heating, sanitary and industrial systems. Installers often use it in wet systems such as underfloor heating, domestic hot water circuits and fire suppression systems. The fitting ensures tight connections in environments with fluctuating temperatures and moderate pressure levels. It is particularly suited for applications requiring corrosion resistance and long-term durability.

In typical installations, this component is used to change the direction of flow in a piping system. It is often found in HVAC systems, solar thermal installations and compressed air systems. The stainless steel construction allows for use in aggressive environments where standard materials might degrade over time. The fitting requires proper crimping to ensure a leak-free connection and must be selected according to the pipe size and system requirements.

Technical parameters

Material	stainless steel grade Wst. Nr. 1.4404 (AISI 316L)
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN70.15
Brand	IVAR

The rated pressure of PN 16 means the fitting can handle systems operating up to 16 bar. The temperature range from -20 °C to +120 °C ensures it is suitable for both cold and hot water applications. These parameters are essential for correct sizing and selection in accordance with system design and operating conditions.

Installation and connection

To install the 90° faced arch, the installer should first ensure that the pipe ends are clean and free from burrs. The fitting is pressed onto the pipe using a compatible crimping tool. The recommended crimping dimension is 54 mm, which must be verified during the process. Common installation errors include improper crimping depth, misalignment of the fitting and failure to check for leaks after installation. It is important to confirm that the seal is intact and that the connection is secure before commissioning the system.

Compatibility and accessories

This fitting is compatible with stainless steel pipe systems of the same material and diameter. It is typically used with other components from the IVAR IVN70 series. For complete system assembly, additional fittings such as straight couplings, unions and valves may be required. Accessories like crimping tools and sealing rings should also be considered when planning the installation.

Technical background for designers

The 90° faced arch functions by providing a directional change in the piping layout while maintaining a sealed connection. The stainless steel material offers high resistance to corrosion and thermal expansion, making it ideal for use in both low-temperature and high-temperature applications. The fitting integrates seamlessly into closed-loop systems and contributes to the overall efficiency and longevity of the installation. The service life is influenced by the quality of the crimping process, the chemical composition of the fluid and the operating temperature range.

Service and operation

No regular maintenance is required for this fitting unless a leak is detected. In the event of suspected leakage, the connection should be inspected for damage or improper crimping. The seal integrity should be visually checked and, if necessary, the fitting replaced. There are no defined service intervals for this component under normal operating conditions.

Frequently asked questions

Can the 90° faced arch be used in solar thermal systems?
Yes, the fitting is suitable for solar thermal applications due to its resistance to thermal cycling and compatibility with hot water.

Is the fitting compatible with other stainless steel pipe fittings?
Yes, provided they are from the same series and have the same nominal diameter and thread type.

What is the maximum allowable temperature for this fitting?
The fitting is rated for a maximum operating temperature of +120 °C.

What should be done if the fitting does not seal properly after installation?
The connection should be rechecked for correct crimping depth and alignment. If the issue persists, the fitting should be replaced.
