Sleeve - N - 15mm IVAR.IVN11

Product detailed description

Steel sleeves like the IVAR IVN11.15 are essential components in the installation of press-fit piping systems, particularly in commercial and industrial buildings. These fittings are commonly used in heating, ventilation, and plumbing systems where reliable, leak-free connections are critical. Installers working on systems such as solar thermal circuits, fire suppression systems, or inert gas lines will find this sleeve suitable for its material properties and pressure capabilities. The sleeve is typically used in environments where the system is exposed to fluctuating temperatures and requires a durable, corrosion-resistant connection method.

Correct selection and installation of the sleeve ensures the integrity of the system and minimises the risk of leaks or failures. The sleeve is used in conjunction with press-fit tools and compatible pipe ends to create a secure joint. It is important to ensure that the sleeve is fully compressed and the press-fit indicator is engaged to the specified dimension to achieve a watertight seal.

Technical parameters

Material	Stainless steel grade 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN11.15
Brand	IVAR

The sleeve is rated for a nominal pressure of PN 16 and can operate within a temperature range from -20 °C to +85 °C, with a maximum of +120 °C. These parameters are critical for sizing the component correctly in relation to the system's operating conditions. The stainless steel construction ensures compatibility with a wide range of fluids and media, including those found in heating and sanitary systems.

Installation and connection

The IVAR IVN11.15 sleeve is installed using a press-fit method. The sleeve is positioned over the pipe end and compressed using a compatible press tool. The connection size is 15mm, and the sleeve must be aligned with the pipe to ensure even compression. The installer should verify that the press-fit indicator is engaged to the specified dimension of 54 mm. Common installation errors include misalignment of the sleeve, insufficient compression, or using an incompatible press tool, which can result in a weak or leak-prone joint.

Compatibility and accessories

This sleeve is compatible with press-fit stainless steel pipes of the same diameter. It requires a press tool suitable for stainless steel press connections. No additional accessories are required for standard installation. The sleeve is not interchangeable with other connection types such as threaded or soldered fittings.

Technical background for designers

The sleeve operates by compressing the pipe wall into the sleeve, creating a mechanical joint that is sealed by the EPDM O-ring. The stainless steel material offers high resistance to corrosion and is suitable for use with a variety of fluids, including those with low pH levels. The sleeve's design allows for easy integration into press-fit systems, where it provides a reliable and long-lasting connection. The service life and efficiency of the component are influenced by the quality of the press operation, the compatibility of the pipe material, and the operating conditions of the system.

Service and operation

No regular maintenance is required for the sleeve during normal operation. However, it is important to inspect the connection periodically for signs of wear or leakage, especially in high-temperature or high-pressure environments. If a leak is detected, the sleeve should be replaced immediately. There are no specified service intervals for this component.

Frequently asked questions

Can the IVAR IVN11.15 be used with copper pipes?
No, the sleeve is designed for use with stainless steel pipes and is not compatible with copper.

Is the sleeve suitable for use in solar thermal systems?
Yes, the sleeve is suitable for use in solar thermal systems due to its temperature and pressure ratings.

Can the sleeve be used with inert gases?
Yes, the sleeve is suitable for use with inert gases as specified in the product description.

What happens if the sleeve is not compressed to the correct dimension?
If the sleeve is not compressed to the specified dimension of 54 mm, the connection may not be watertight and could result in a leak.
