  • Patent number: 10406577
    Abstract: A method of making mechanically-lined pipe with primary expansion by plastically expanding a liner sleeve within an outer pipe, under lining pressure applied internally to the liner sleeve. On relieving the lining pressure, elastic radial contraction of the outer pipe makes a mechanical bond between the outer pipe and the liner sleeve. Then, secondary expansion of the outer pipe is performed under fixing pressure, which may be greater than the lining pressure, applied internally to the liner sleeve at an end portion of the pipe. This makes or strengthens a mechanical bond at the end portion. The resulting pipe joint has an end portion and a body portion inboard of the end portion. The body portion has a first, lesser bonding pressure between the outer pipe and the liner sleeve. The end portion has a second, greater bonding pressure between the outer pipe and liner sleeve.

  • Patent number: 10036488
    Abstract: A process for manufacturing pipes using thermoplastic pipe and “tape” (continuous fiber, fully wetted in a similar thermoplastic as the pipe) that embeds the fibers into pipe surface. In one embodiment, an ambient temperature (72 degrees F.) tape is tightly wrapped around the cold pipe in a dry environment (relative humidity below 30). An external heat source is used to heat up the entire length of the pipe causing the thermoplastic to melt and the pipe to expand due to thermal expansion. Since the fibers have less stretch than the thermal expansion of the pipe the fibers will be embedded into the molten layer of the pipe, creating a permanent bond between the fibers and the pipe. A protective film is applied to the pipe. Portions of the tape and film are scraped from the surface of the pipe creating an area where the end of the pipe is coupled to another pipe using an electronic fusion coupler.

  • Patent number: 9545660
    Abstract: In order to produce a formed part furnished with a through hole, a rod material is advanced by a defined length in the direction of its lengthwise extension into a forming die through a stationary guide and then immobilised by a clamping arrangement that engages with it circumferentially. The end portion of the rod material is then axially swaged by a swaging tool and is thus shaped into a disc, the circumference of which is defined by the forming die. The disc is then penetrated axially by a dishing tool and impact extruded at the same time, the displaced material flowing between the dishing tool and the inner circumferential wall of the forming die. The formed part located in the forming die is then rotated coaxially relative to the rest of the rod material and thereby separated from the rest of the rod material by torsion shearing.

  • Patent number: 8627854
    Abstract: Pressure cast lined steel pipes comprise an annular concrete or mortar liner along an inside diameter, and a metal shell surrounding the liner, wherein the liner is in direct contact with the metal shell. The wall thickness of the liner can be from 10 to 50 times the thickness of the metal shell. The pipe may be coated with a dielectric material. A mold assembly used to form the pipe includes an annular concrete or mortar composition chamber formed between the metal shell and an inner mold member. Pressurized water is used in the mold assembly to pressurize the concrete or mortar composition and exert a desired pressure force onto the metal shell while the composition cures in the mold. Once a desired degree of cure is achieved, the pressure is removed causing the metal shell to exert a desired compression force onto the cured liner.
