The pipeline includes a pipe that defines a pipeline conduit and an energy dissipation layer that is within the pipeline conduit and through which a portion of the slurry flows. The slurry may flow at high velocity and/or with high turbulence, and it may contain hydrocarbons. The systems and methods may include an energy dissipation layer to decrease the kinetic energy of a buffer portion of the slurry that flows through the energy dissipation layer relative to the kinetic energy of a central portion of the slurry that flows through a central region of the pipe. This decrease in the kinetic energy of the buffer portion of the slurry may decrease abrasion of the pipe by the slurry.

  • Patent number: 9016324
    Abstract: A method to form a pipe system which meets level II fire endurance standard according to IMO A 18/Res.753 fire testing protocol, for use in oil, gas, exploration, refining and petrochemical applications is provided. In the pipe system, each pipe section comprises a plurality of layers, an inner layer in contact with the corrosive petroleum product comprising a thermoplastic material, a structural layer comprising a composite material, and an outer layer comprising a fire resistive material. The method comprises applying energy to join the corrosion resistant layers of the separate pipe sections together forming a joint, applying an external wrap around the joint and at least a portion of the composite structural layers of the at least two pipe sections, and bonding the external wrap to the joint and the composite structural layers by chemical curing, thermal treatment, or combinations thereof.

  • Patent number: 8997798
    Abstract: A refrigerant line for carrying a mixture of refrigerant and lubrication oil. The line includes an inner casing made of a material impermeable to the refrigerant/oil mixture, an outer casing made of a material that is highly permeable to the refrigerant in its gaseous state, and an intermediate layer between the inner and outer casings made of a material that is high permeable to the gaseous refrigerant but that is able to retain the admixed oil. In this way, any oil contained in a refrigerant/oil mixture leaking through the inner casing is retained by the intermediate layer, while the refrigerant gas is allowed to escape through the outer two layers. The intermediate layer may retain the oil by absorption, by adsorption, or by binding of the oil.
