Flexible Risers

Flexible risers are now more common in recent years due to the increase in deep water oil and gas exploration. The flexible riser is a connection between typically a floating production system, and the subsea well or pipeline and often a means of transporting Oil & Gas. A Flexible Riser is composed of both metallic and polymer layers designed for optimal strength, weight, and flexibility under high pressures and temperature variances. The polymer sheath layer contains the process fluid and consists of certain types of polymers to form a pressure barrier that has to be resistant to chemical and mechanical degradation over time.
