Cylinders Chesterfield Special Cylinders (CSC) has over a century of industry knowledge and expertise and is a world-leading provider of bespoke, high-pressure gas containment solutions and services. It is one of only five companies globally which can compete for ultra large cylinder contracts. CSC’s high-pressure cylinders are a critical component for a number of end applications, from high-pressure systems in naval submarines and surface vessels to oxygen cylinders in fighter jets, from the bulk storage of industrial gases to air pressure vessels in floating oil platform motion compensation systems and more recently for hydrogen transport refuelling and energy storage.
