This concise and timely practitioner guide offers a comprehensive theoretical background and a design procedure for hoop-wrapped composite gas cylinders. It provides insight into the effects of process variables and how they interact, allowing a predictive approach to design, enabling test results to be assessed in a more meaningful way. The theory is also generally applicable to all kinds of internally pressurized cylindrical pressure vessels and pipes where hoop reinforcement is an integral part of the design. The author has served on numerous standards committees and has over 45 years experience in the industry.
