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).
Claims32
A spoolable pipe, 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 is solid at about 25° C. and said matrix comprises hydrocarbons having an average molecular weight of less than about 20,000 grams/mole;
- and
- an external layer enclosing the at least one reinforcing layer.

A spoolable pipe, 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 matrix wherein said solid matrix has a tensile modulus between about 10 and 90,000 psi, and wherein said reinforcing layer is formed at least by applying to said fibers a substantially liquid matrix composition having a viscosity between about 10 and about 10,000 cPs at 25° C.
