Faced arc 15° - N - 18mm IVAR.IVN75

Product detailed description

This faced arc is commonly used in residential and commercial buildings for connecting piping systems at an angle. It is suitable for a variety of applications such as heating systems, water supply lines, fire sprinkler systems and industrial installations. The press-fit connection ensures a secure and leak-free joint when properly installed. Installers working on these systems will benefit from the component’s durability and ease of use in tight spaces.

The stainless steel construction provides resistance to corrosion and ensures long-term performance in environments with fluctuating temperatures. The design allows for integration into both new builds and renovation projects, particularly in areas where space constraints make traditional fittings difficult to use. The 15° angle is especially useful for directional changes in piping layouts that require minimal space.

Technical parameters

Material	Stainless steel grade 1.4404 (AISI 316L)
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN75.18
Brand	IVAR

The nominal pressure rating of PN 16 indicates that the component is suitable for systems operating under moderate pressure conditions. The material grade 1.4404 (AISI 316L) is selected for its resistance to corrosion and mechanical stress, making it appropriate for use with a range of fluids and gases. The operating temperature range ensures compatibility with both cold and warm water systems as well as low-temperature heating circuits.

Installation and connection

The installation process involves pressing the fitting onto the prepared pipe end using a compatible press tool. The correct connection requires the pipe to be cut square and free from burrs. The press tool must be aligned precisely with the fitting to ensure even compression around the circumference. After pressing, the indicator mark should align with the specified dimension to confirm a successful connection. Common installation mistakes include misalignment during pressing and using an incorrect tool size. These errors can lead to leaks or reduced joint integrity. Installers should verify the press depth and check for visible deformation of the fitting after installation. A secure connection is essential for maintaining system pressure and preventing failures over time.

Compatibility and accessories

This faced arc is compatible with press-fit stainless steel piping systems of the same material grade. It is intended for use with pipes of matching diameter and wall thickness. Additional components such as straight couplings, elbows and tees may be required to complete the installation. Accessories such as press tools and cutting devices should be selected according to the manufacturer's specifications to ensure proper installation.

Technical background for designers

The 15° angle of this faced arc allows for directional changes in piping layouts while minimising spatial requirements. The stainless steel material offers high resistance to chemical and thermal stress, making it suitable for both aggressive and neutral media. The press-fit connection relies on the deformation of the fitting around the pipe to create a hermetic seal. Designers should consider the expansion and contraction of the system due to temperature variations and ensure sufficient flexibility in the layout to accommodate these changes.

Service and operation

Regular inspection of the joints is recommended to detect early signs of wear or potential leaks. Any visible damage to the fitting or pipe should be addressed immediately to prevent system failure. There are no specific service intervals provided for this component, but it is advisable to perform checks during routine maintenance of the entire system. Proper installation is critical for ensuring long-term performance and avoiding the need for frequent repairs.

Frequently asked questions

Can the IVN75.18 be connected to press-fit stainless steel piping?
Yes, the IVN75.18 is specifically designed for use with press-fit stainless steel pipes. The connection is made using a compatible press tool to compress the fitting around the pipe.

What is the maximum operating temperature for this faced arc?
The component is rated for a maximum operating temperature of +120°C. It is suitable for both cold and warm water systems as well as low-temperature heating circuits.

Is this fitting suitable for use in fire sprinkler systems?
Yes, the IVN75.18 is approved for use in fire sprinkler systems. The stainless steel construction and press-fit connection provide reliable performance in high-pressure environments.

What should be checked after installation to ensure a secure connection?
After installation, the press depth should be verified against the manufacturer’s specifications. A visible indicator mark should align with the correct dimension to confirm that the joint is fully compressed and secure.
