Pressure-expandable conduit liner |
摘要 |
Conduit liners and methods for their construction and use are provided. The liners include a first flexible layer mechanically bonded to at least one glass-containing layer and folded to form a tubular laminate. The laminate can be penetrable by resinous liquid capable of setting the form of substantially continuous matrix within the laminate following the expansion of the laminate within a conduit. In preferred versions of the liner, multiple glass layers are provided on the inner and outer diameter of the construction with a polyester core so as to meet minimum thickness requirements for vibration resistance under American in situ pipe vibration resistance codes.
