PP-R loop compensation - 32 1209036004

PP-R Loop Compensation – Reliability and Durability of Installation

The PP-R loop compensation with a diameter of 32 mm is a key element of the KAN-therm PP system, designed for hot and cold water installations and central heating. Its task is to absorb thermal expansion of pipelines, minimizing stress and ensuring long-term tightness of connections. Made of random polypropylene (PP-R) – a material resistant to corrosion and high temperatures – guarantees trouble-free operation for years.

Construction and Application

The loop compensation is an element connecting sections of PP-R pipes, allowing compensation for thermal expansion. This prevents the formation of stress in the installation, which could lead to its damage. This product finds application in both domestic installations and multi-family buildings and industrial facilities. Its versatility makes it ideal for new installations as well as modernization of existing ones. Connection is made by polyfusion welding, which ensures a durable and tight connection.

Advantages and Benefits

• Absorption of expansion: Effectively compensates for linear expansion of pipelines up to 50 mm, reducing the risk of damage caused by thermal stress.
• Durability and resistance: Made of high-quality random polypropylene (PP-R) provides resistance to corrosion, high temperatures (up to 90°C) and pressure (up to 6 bar in C.H. systems).
• Tightness: Polyfusion welding guarantees a durable and tight connection of installation elements.
• Versatility: Can be used in cold water, hot water and central heating installations.
• Compliance with standards: The product meets the requirements of PN‑EN 15874 standard, which confirms its high quality and safety of use. It has CSTB, ITB, Lloyds and PZH certificates, which further increases confidence in the product.
• Minimization of pressure loss: Lack of constrictions in the fitting design translates to minimization of pressure loss in the installation.
• Long warranty: The manufacturer offers a 10-year warranty (in the case of individual construction even 15 years), which proves its high quality and reliability.
• Linear thermal expansion coefficient α: 0.15 mm/mxK – an important parameter in the design of installations taking into account changes in pipe length under the influence of temperature.
• Thermal conductivity λ: 0.24 W/mxK – affects the effectiveness of thermal insulation of the installation.
• Minimum bending radius Rmin: 8.0 D mm – allows for flexible routing of pipelines even in tight spaces.
