Thin Walled Polyester Reinforced PE Lining for Potable Water Pipeline Renovation [PE]

This paper relates experience gained using Thermopipe. a Thin Walled Polyester Reinforced Polyethylene (PRP) pipe for the rehabilitation of water mains. Some 46km have now been installed world wide, with the bulk of the work carried out in the UK, where 12 water companies have used the system. The Paper also desci-ibes the development of special fittings to connect the lined pipes to other mains and service pipe work : patented service connections having been developed for installation in water mains in both live pressure and dead applications.
