Compensation Loop Detal-met KOMP25 PP 25 — Pętla kompensacyjna for plumbing systems

Compensation loop Detal-met KOMP25 PP 25 is a factory-made expansion loop intended to absorb axial thermal expansion and contraction in piping systems made with PP 25 pipes. The product follows the KOMP25 specification and is designed to reduce linear stress on pipe joints, fixtures and supports by providing a controlled flexible section that compensates for length changes caused by temperature fluctuations in heating, hot-water and industrial pipelines.

Advantages

The compensation loop offers a simple mechanical solution to axial movement without the need for complex fittings or special anchors. Its design reduces load transfer to connection points and minimizes the risk of leakage or premature wear. Installation time is typically short because the loop is prefabricated to match PP 25 pipe dimensions, ensuring consistent geometry and predictable performance. The component is compatible with standard PP 25 piping practices and materials, enabling straightforward integration into existing systems.

Suitable for

• Heating systems with PP 25 piping
• Domestic and commercial hot-water pipelines using PP 25
• Industrial pipelines where axial expansion compensation is required
• Retrofit projects to reduce stress on existing joints and supports

Key specifications

• Designed for PP 25 pipe diameter and fittings
• Prefabricated expansion loop geometry for axial compensation
• Suitable for use in systems transporting heated water and general fluids compatible with polypropylene piping
• Reduces axial forces transmitted to joints and supports

How to use

Install the compensation loop in a straight run of PP 25 piping where axial movement is expected. Align the loop so that its plane allows free deforming under thermal changes and ensure that connected pipes are supported at recommended intervals to prevent unwanted bending. Use appropriate fusion or mechanical joining methods for PP 25 pipes as specified by the piping system instructions. After installation, check alignment and clearances to confirm the loop can expand and contract without obstruction.

Usage recommendations

Locate the loop at a distance from rigid fixtures and valves to allow full movement; avoid constraining the loop with nearby structural elements. Verify system operating temperatures and select installation positions that permit the loop to perform axial compensation effectively. Routine inspections during initial operation are recommended to confirm correct behavior under thermal cycling.
