Abstract
A spoolable pipe is disclosed, the spoolable pipe having an internal pressure barrier formed about a longitudinal axis, and a reinforcing layer(s) enclosing the internal pressure barrier that includes a solid hydrocarbon matrix. The pipe can also include an energy conductor(s) integrated with and/or located between the internal pressure barrier and/or the reinforcing layer(s).
Claims15
A spoolable pipe for use with transported fluids pressurized between about 1 psi and about 1,000 psi, comprising:
- an internal pressure barrier formed about a longitudinal axis;
- at least one reinforcing layer enclosing the internal pressure barrier and comprising fibers and a solid hydrocarbon matrix, wherein said solid hydrocarbon matrix has a tensile modulus of about 100 to about 10,000 psi, wherein said solid hydrocarbon matrix is solid at about 25° C. and said matrix comprises hydrocarbons having an average molecular weight of less than about 20,000 grams/mole, wherein said hydrocarbons are selected from the group consisting of wax, grease, elastomers, tar and asphalt;
- and
- an external layer enclosing the at least one reinforcing layer.
