Technical Information

Liner
  Gaine dessin
      

Aqua Pipe® is composite material i.e. woven polyester jackets (with a polymeric membrane bonded to the interior to ensure watertightness) and specific epoxy resin.

It is available in 6 to 24 inch (150 to 600 mm) diameters for water main distribution systems.

Structural Capacity

Aqua Pipe® is designed and installed according to ASTM F 1216 and ASTM F 1743 Standards.  It is designated as a Class IV fully structural liner when compared to the AWWA M28 structural classification. This means that Aqua-Pipe® is a stand-alone structural liner that can withstand all dead and live loads and internal pressures, including a vacuum,  without the help of the residual strength of the existing pipe. If the host pipe is depressurized. Aqua-Pipe® can withstand operating pressures up to 150 psi.

Certification

 Aqua Pipe® is certified by NSF/ANSI Standard 61, UL,BNQ 3660-950, and is a WRAS  approved product (BS6920).

 

Installation

Aqua-Pipe® is impregnated onsite with specific epoxy resin and is then pulled in place through the host pipe. The Aqua-Pipe® liner is shaped by pushing a pig through the liner using water pressure and then cured with circulating hot water (CIPP).

Service Connections

The service connections are reinstated from within the pipe using a remote controlled mechanical robot. A closed-circuit television (CCTV) system is used to monitor the operation. Watertightness is preserved by the resin that surrounds the threaded cavities of the service connections and ensures a tight bond with Aqua-Pipe®
