    摘要： A compression apparatus (10) for compressing a tubular structure (12) to be formed into a hollow structure (20) such as a pipe comprises contact elements (60) arranged in two sets, (61, 62). The contact elements (60) are adapted to move along a compression section (41) in a coordinated sequence, whereby a portion (12a) of the tubular structure (12) within the compression section (41) is compressed between pairs (63) of opposed contact elements. The apparatus (10) includes registration means (110) for causing respective pairs (63) of opposed contact elements (60) to be maintained in registration with each other while moving along the compression section (41).

    摘要： A method and apparatus for making a pipe liner and the pipe liner itself. A thin walled pipe liner, after being provided cooled from a spool or extruded in tubular form and cooled, is deformed to a smaller cross section at ambient temperature. The pipe liner is then encased and held in its reduced cross section deformed shape by a protective sleeve which is co-extruded directly over the pipe liner. The sleeved pipe liner may then be wound on a drum for transport to a remote location. Ducts for water may pass through the pipe liner. Other ducts, for example, for fiber optics, may pass through the sleeve either within or outside of the deformed pipe liner.

    摘要： A method for lining a conduit with a deformable plastics liner pipe, the claimed method including deforming the liner along its length to a cross-section with reduced external dimensions relative To the dimensions of the undeformed liner and binding the liner by helically winding an elongate flexible element around the liner along its length to maintain it in the deformed cross-section. The method further includes drawing the bound liner into the conduit to be lined and releasing the binding to allow the liner to assume a cross-section substantially corresponding with the internal cross-section of the conduit. The elongate flexible element is supplied to the liner from a bobbin or the like through which the liner is passed in the deformed cross-section, the bobbin or the like being mounted for rotation around the liner as it passes therethrough to wind the elongate flexible element around the liner.

    摘要： A method and apparatus for forming sealed and reinforced holes through the end of a flexible, resin-impregnable, tubular pipe liner for securing a cable thereto and for sealing the end of the liner. The liner is installed into an existing conduit either by pulling a cable secured to holes at the front end of the liner or by eversion of the liner while securing a hold-back cable to holes at the trailing end of the everting liner. Holes are cut through the liner, and resin is impregnated into the region about each hole and hardened to form an integral grommet or reinforcement. A mold for impregnating the region about the hole includes a lower mold body with a projecting spigot and a groove thereabout. An upper mold body has a central opening with a groove thereabout, the upper mold body fitting over the spigot. A tube fits into the central opening and receives a resin, which is then forced by a plunger down the tube and allowed to harden and form a secure and reinforced hole for attaching a pull-in or hold-back rope or cable.

    摘要： A method is provided for lining a pipe wherein a thermoplastic liner is initially formed in a cylindrical shape with a diameter slightly larger than the internal diameter of the pipe. The liner is temporarily deformed at an elevated temperature to a different cross-section, preferably U-shaped, to reduce its overall cross-sectional dimension to facilitate insertion into the pipe to be lined. The deformation occurs with substantially comparable elongation of the pipe lining along its opposite sides thereby precluding variations in wall thickness and stress in the pipe. Once inserted, the liner is pressurized and reheated first to a temperature below its crystallization temperature to round the lining in the pipe and subsequently, further pressurized and reheated to a second temperature higher than the crystallization temperature to cause the liner to retain its original round shape.
