COOLFLEX

Product catalog summary

System Description
COOLFLEX is a flexible pipe system by Brugg Pipe Systems, designed for local and district cooling networks, industrial applications, and with some restrictions, for combined heat pump systems. It utilizes high-density polyethylene (PE100) pipes, suitable for drinking water, wastewater, and gas supply. The pipes are insulated with CFC-free polyurethane foam, allowing for minimal underground connections, which reduces installation time and costs.

Specifications
- Operating Temperature: -20 to +40 °C
- Operating Pressure: Max 16 bar
- Pipe Material: Polyethylene class PE100
- Insulation: CFC-free polyurethane foam

COOLFLEX Range
The range includes pipes with dimensions from DN 20 to DN 125, available in coils. These pipes are flexible, facilitating easy installation over or under existing infrastructure.

Pressure Loss Charts
Charts are provided for water and ethylene glycol, detailing pressure loss across various pipe dimensions and flow rates.

Components
Details on components such as house entry bends, L-shells, I-shells, T-shells, and jointing methods are provided. Each component ensures secure connections and efficient insulation.

Installation
Guidelines for underground construction and installation include pipe routing, trench dimensions, and open installation methods.

Jointing Methods
Several jointing methods are described, including screwed connectors, fusion welded joints, and alternative connections, ensuring flexibility and reliability in various installation scenarios.

Heat Losses
Heat loss data is provided for different pipe dimensions, with calculations based on installation type and environmental conditions.

PE Jointing Methods
The document outlines methods for jointing polyethylene (PE) pipes, including screwed connectors, T-pieces, and fusion welded sleeves. Materials used are primarily brass and PE 100/SDR 11, suitable for cold water applications at 16 bar pressure. Detailed specifications for different pipe diameters and their corresponding sleeve dimensions are provided.

Technical Specifications
Tables list dimensions for PE pipes, sleeves, and T-pieces, with measurements in millimeters. It specifies the outer diameter, wall thickness, and lengths for various configurations, emphasizing the importance of selecting the correct size for effective jointing.

End Closures and Sealing
COOLFLEX shrink-on closures and end caps are discussed as methods to protect pipe ends. These closures are made from heat-shrunk, cross-linked polyolefin and are coated with sealing adhesive, designed to prevent water and gas ingress but are not fully watertight in flooding conditions.

Building Entry and Wall Sealing
Guidelines for wall sealing rings and building entry installations are provided, including specifications for wall openings, core bores, and the use of sealing sets to ensure tightness. Recommendations are given for sealing borehole walls to prevent leaks.

Pipe Routing and Trench Dimensions
Instructions for trench dimensions and pipe routing are provided, including minimum bending radii and installation depths. The document specifies the use of pipe warning tape and sand as backfill material, with considerations for traffic load impacts on trench depth.

Surface Installation
Special measures for surface installation of COOLFLEX district cooling pipes are outlined, including the use of supports, clamps, and pressure distribution plates. The document emphasizes the need for design engineering assistance for proper installation.
