  • Patent number: 8631553
    Abstract: A tube splicing machine is provided which includes a frame on which a die holder is located. A swaging die is removably mounted in the die holder, and the die holder includes a main plate and a top plate that is removably connected to the main plate. A die holding opening is defined through a portion of the main plate and the top plate in which the swaging die is inserted. The swaging die includes two die parts that together define a die opening and are separable along a mid-line of the die opening. A splice fitting engagement plate with a splice fitting engagement portion is located on the frame, with the splice fitting engagement plate having an opening or an openable top to allow removable connection to a splice fitting. An actuator is connected between the splice fitting engagement plate and the die holder for moving the splice fitting engagement plate relative to the die holder from an initial position to a swaged position, in order to swage the splice fitting onto a length of hose or tubing.

  • Patent number: 6978843
    Abstract: A well configuration and method of increasing production from a hydrocarbon well having pre-existing production tube. A composite velocity string having an outer diameter smaller than the inner diameter of the production tube is installed in the production tube so that an annular gap is formed between the outer surface of the velocity string and the inner surface of the production tube. Production from the well is increased because the coefficient of fluid flow friction through the composite velocity string, and the amount of heat loss through the composite velocity string, are reduced compared to a steel velocity string. Installation efficiency is also increased because the composite velocity string is much lighter than a steel velocity string.

  • Publication number: 20040035485
    Abstract: A multi-layer, composite material, and products made therefrom, having the combined properties of high strength, high chemical resistance, and low permeation to chemicals and gas. The multi-layer composite material has a barrier layer, an intermediate binding layer, and a support layer. The barrier layer is polyphenylene sulfide compounded with an ethylene/glycidyl methacrylate copolymer. The intermediate binding layer is ethylene/glycidyl methacrylate copolymer. The support layer is polyamide compounded with an ethylene/glycidyl methacrylate copolymer.

  • Publication number: 20030178201
    Abstract: A method of installing a self-supporting liner in a pipe section having an inner diameter DP. The liner includes a continuous tube of polymeric material, a braided sheath surrounding the tube, and an outer jacket surrounding the braided sheath. The liner has a relaxed outer diameter that is greater than DP. The diameter of the liner is temporarily reduced by applying a tensile load to the liner, which causes the braided sheath to radially compress the continuous tube of polymeric tubing. The liner is inserted into the pipe section while maintaining the radially-compressive force on the liner until the liner has been positioned along the desired length of the pipe section. The tensile load is then removed and the liner is maintained in the pipe section until the diameter of the pipe liner relaxes and forms an interference fit with the inner wall of the pipe section.
