CPV Hiline Aqua - Rigid Pre-Insulated Polymer Pipe System
From Hiline Pre-insulated Pipe Systems
A pre-insulated pipe system for district heating, cooling and potable water applications. Hiline Aqua is a rigid, pre-insulated polymer pipe system specifically developed for the next generation of district heating, cooling and hot water service networks. Whether it’s for a simple connection between two buildings or a large-scale network, it offers outstanding thermal performance coupled with exceptional levels of reliability.
Product Overview
Polypropylene (PP) Service Pipe
A polymer composite pipe manufactured from three-layer polypropylene random copolymer (PP-R), mechanically strengthened by fibre to dimensions and tolerances as specified in DIN 8077 Type 2 (PP-B) and quality standards and testing regime to DIN 8078 Type 2 (PP-B).
Intended for heating and cooling networks operating between -20°C and 95°C and with a WRAS-approved service pipe option for hot potable water services.
Tough Outer Casing
Manufactured in HDPE to the requirements of the EN253 standards, the tough and resilient outer casing enables the pipe to be buried directly in the ground – so ensuring the network’s insulation integrity is maintained throughout its service life.
High-Performance Insulation
A layer of CFC-free rigid polyurethane foam provides outstanding insulation properties, with values of 0.022 W/mK and with the insulation thickness according to the Series 1 requirements of EN 253. With the service pipe and outer casing being bonded together by the foam insulation, the system far out-performs other systems with an air gap. With this increased efficiency, comes lower heat loss and therefore a saving in both operational costs and carbon emissions.
For even greater efficiency, Hiline Aqua pipe systems are also available with increased insulation thickness to series 2 and series 3.
Complete System
Hiline Aqua has a comprehensive range of pre-fabricated bends, tees, fittings and accessories that enable it to be adapted to meet all possible configurations – including transitions to other types of pre-insulated pipe systems – such as Hiline Steel or Hiline Flex. Hiline Aqua can be offered as off-site pre-fabricated fittings and spool assemblies to meet a client’s bespoke requirements – significantly reducing installation time and cost.
Robust and Adaptable Joints
The Hiline Aqua PP-R service pipe is perfect for thermoplastic welding techniques, including electro fusion, butt fusion and socket fusion.
The HDPE outer casing can be joined using the proven Hiline range of wrap-around heat-shrink or electro-fusion couplings to ensure the very tightest of joints to protect against the ingress of ground water.
Trace Heating and Leak Detection Options
All of the Hiline Aqua range is available with the option of integrated trace heating cables to protect the media temperate and leak detection systems that warn of moisture ingress into the insulation.
Standards
Hiline Aqua pre-insulated pipes and fittings for thermal utilities are manufactured within an ISO 9001 accredited environment, generally in accordance with the requirements of EN 253 and in compliance with EN 448, EN 488, EN 489 and EN 13941
