VESTAMID® NRG polyamide 12 and VESTAKEEP® PEEK are materials with strong track record in subsea applications and are available for multiple functions in TCP and TCR design:
- as a liner material suitable for multi-phase operations
- as a jacket material protecting the reinforcement layer against the environment
- as a matrix material of the reinforcement layer
Evonik has developed tailored PA12 and PEEK allowing the production of high quality unidirectional fiber tapes VESTAPE® used for the reinforcement layer. The focus of this development was an optimized fiber matrix bonding and resistance to hydrolysis. The tapes are used to form continuous pipes and pipe sections. VESTAPE® UD tapes are available with glass fibers and carbon fibers.
Thermoplastic Composite Pipes (TCP) and Thermoplastic Composite Risers (TCR) for the oil & gas offshore industry are getting more and more awareness. Today these types of pipes are used in relatively short-term applications while developments on long-term applications are progressing. Due to their minor weight compared to conventional pipes TCP and TCR can explore oil and gas from currently unreached subsea areas.
