  • Patent number: 11320084
    Abstract: Methods and systems for installation of a liner inside a conduit (e.g., water pipe) to transport a fluid (e.g., potable water) to rehabilitate the conduit, in which the liner can be installed, and thus the conduit can be rehabilitated, more efficiently, including, for example, by further reducing an extent of digging that may have to be done, by testing more readily (e.g., pressure-testing for watertightness or other fluid-tightness once installed), and/or by adapting to a cross-sectional size of the conduit. Also, the liner may be thinner, interact better (e.g., less) with the fluid flowing through the conduit, and/or be otherwise designed to enhance its use and performance.

  • Patent number: 11287066
    Abstract: A hose that includes an inner layer and an outer layer made of an elastic polymeric material, and a textile reinforcement layer interposed between the inner and the outer layers. The inner layer and the outer layer are reciprocally coupled to form a unitary tubular member, within which the textile reinforcement layer is embedded. The unitary tubular member has an elasticity such to automatically elongate under the working pressure given by the liquid flowing therethrough to increase its original length and to automatically recover once the working pressure stops. The textile reinforcement layer is adapted to move from a rest configuration when the working pressure stops to a working configuration when the unitary tubular member elongates under the working pressure, and vice versa.
