    Abstract: In a pipe (1) coated with a resin layer (4) on the inner surface thereof and a method for manufacturing the same, resin mixture including thermal melting fluoro resin and fluorine elastomer is applied to the inner surface of a pipe member. The resin mixture is thermally treated on the inner surface of the pipe member to be of a mesh like pattern so that a resin layer of a predetermined stripping strength is obtained thereon.

    Abstract: A method of manufacturing a length of lined pipe inserts a radially contracted liner pipe into an outer host pipe. Injector needles are inserted through an end of the outer pipe into an annular gap between the pipes. Adhesive is injected between the pipes at locations inboard of the end of the outer pipe. After withdrawing the injectors, at least a portion of the liner pipe is expanded to close the gap and to bond the pipes together via the injected adhesive. Shims can be inserted into the gap between the pipes. A portion of the liner pipe inboard of the shims can be expanded radially while the shims constrain local radial expansion of an outboard portion of the liner pipe to maintain the gap for accommodating the injectors. Withdrawing the shims after injecting the adhesive allows radial expansion of the outboard portion to close the gap between the pipes.

    Abstract: A prefabricated composite concrete element for use in a corrosive sewer environment. The concrete element has a hollow reinforced cast concrete portion with at least one end having connection details, a premolded corrosion resistant inner plastic liner. The plastic liner lines an interior of the hollow concrete element and the connection details to provide abutting liner faces in an assembled joint to limit exposure through said joint of said concrete portion to corrosive materials arising in said sewer environment. At least two prefabricated composite concrete elements may be assembled end to end at a joint to form a concrete sewer system. Also disclosed are a method of prefabricating such a composite concrete element.

    Abstract: A connector used for connecting the plastic metallic pipe includes a body, a cap, and three washers. The body has a section of thread in its outer wall for coupling with the cap which has a section thread in its inner wall. In operation, first insert the pipe into the cap, then insert the rubber washer, the metallic washer, and spring washer into the body, and then screw the cap into the body, such that the pipe is locked with the body.

    Abstract: A method for installing a fiberglass or stainless steel liner into a steel casing which results in a reduction of strain on the casing. Conventional means are used to place the liner into the casing and to fill the annular space with cement. Thereafter, maximum design operating pressure on the liner is maintained while the pressure on the annular space is reduced; maintenance of those pressures keep the liner in an expanded state while the grout cures. As a result, the liner shares the load with the casing; pressure from the fluids contained in the system during operation is not transferred to the casing through the grout until the liner's preset internal pressure is reached. The use of the method greatly reduces the possibility of flowline failure.

    Abstract: A method of lining a pipe conduit to provide superior corrosion resistance. A flexible lining hose, having a resin absorbent layer which has been introduced with a volume of high strength resin, is first positioned inside of the conduit. The lining hose is then expanded into contact with the inner diameter of the conduit by inverting a calibration hose. The calibration hose has an impermeable membrane and a layer of resin absorbent material that has been introduced with a volume of corrosion resistant resin. The calibration hose is inverted by use of fluid pressure inside the lining hose, the fluid pressure being exerted against the impermeable membrane of the calibration hose. The resin layers are then cured by the application of a heated fluid until the lining hose and the calibration hose form a unitary rigid self supporting liner.
