IVAR Alpex - Duo XS disc 26 x 3, 83526201

Product detailed description

IVAR Alpex - Duo XS pipe discs are used in residential and commercial buildings for heating and plumbing systems. These discs are typically installed in underfloor heating systems, radiator heating circuits and sanitary water distribution. The PE-AL-PEX material provides good thermal stability and resistance to thermal expansion, making it suitable for systems with fluctuating temperatures. Installers working with these discs must ensure correct sizing and connection methods to maintain system integrity and efficiency.

These discs are commonly used in multi-storey buildings, single-family homes and industrial facilities where reliable and long-lasting piping solutions are required. The discs are pre-cut and packaged in 50 m lengths, allowing for efficient installation with minimal waste. The operating temperature of up to +95 °C makes them suitable for systems with high thermal demands, such as central heating and hot water distribution. The nominal pressure rating of PN 10 ensures compatibility with standard heating and plumbing systems.

Technical parameters

The nominal pressure of PN 10 indicates the maximum pressure the pipe can withstand under normal operating conditions. The operating temperature of +95 °C is suitable for heating systems and hot water distribution. These parameters are essential for correct sizing and selection to ensure the pipe can handle the expected load and thermal conditions without failure.

Installation and connection

The IVAR Alpex - Duo XS disc is connected using TA, RA crimping or press fittings. Installers must ensure that the correct tools and fittings are used to achieve a secure and leak-free connection. The pipe has a standard outer diameter of 26 mm and a wall thickness of 3 mm, which must be verified before installation. Common installation mistakes include using incorrect crimping tools or failing to clean the pipe surface before fitting installation. It is also important to check the alignment of the pipe and fittings to prevent stress on the joints.

Compatibility and accessories

The IVAR Alpex - Duo XS disc is compatible with standard heating and plumbing systems that use TA, RA crimping or press fittings. It is suitable for use with underfloor heating systems, radiator heating and sanitary water distribution. To complete the installation, additional accessories such as crimping tools, press tools and fittings must be ordered separately. These accessories are essential for ensuring a secure and reliable connection between the pipe and the system components.

Technical background for designers

The PE-AL-PEX construction consists of a polyethylene layer, an aluminium layer and a cross-linked polyethylene layer. The pipe is integrated into the system by connecting it to fittings using TA, RA crimping or press methods. The service life and efficiency of the pipe are influenced by the quality of the installation, the correct selection of fittings and the operating conditions of the system. The material properties ensure long-term durability and resistance to corrosion.

Service and operation

Regular inspection of the pipe connections is recommended to ensure there are no leaks or signs of wear. The pipe should be checked for any damage or deformation that could affect its performance. No specific service intervals are provided in the brief, but it is advisable to follow the manufacturer's recommendations for maintenance and inspection. The pipe is designed for long-term use and requires minimal maintenance under normal operating conditions.
