Abstract

Provided herein are systems and methods for reinforcing a high-temperature, high pressure pipe. In one embodiment, a reinforcing material (e.g., carbon fiber) and an epoxy resin composition are applied to an inner or outer surface of a pipe. The epoxy resin composition is cured in situ, thereby forming a cured composite material attached to the inner or outer surface of the pipe. The cured composite material comprises a cured epoxy resin composition having a Tg of at least about 250° F. (121.1° C.).

IPC Classes  ?

• B32B 5/02 - Layered products characterised by the non-homogeneity or physical structure of a layer characterised by structural features of a layer comprising fibres or filaments
• B32B 1/08 - Tubular products
• B32B 37/24 - Methods or apparatus for laminating, e.g. by curing or by ultrasonic bonding characterised by the properties of the layers with at least one layer not being coherent before laminating, e.g. made up from granular material sprinkled onto a substrate
• B32B 38/00 - Ancillary operations in connection with laminating processes
