Hexagon Lincoln has been a member of the Hexagon Composites Group of companies since 2005. The Group develops and supplies composite cylinders for storage and transportation of liquefied petroleum gas, compressed natural gas, biomethane, compressed hydrogen gas, and other industrial gases. 50 years fabricating advanced filament-wound composites Hexagon Lincoln has been making filament-wound fuel tanks since before America sent a man to the moon. Our heritage began in 1963 with filament-wound rocket motor cases. Soon after we expanded into high-pressure composite vessels for aircraft, missile, satellite, and launch vehicle programs. This experience made us a logical choice when NASA needed lightweight vessels for its manned missions. In fact, many of the components and pressure vessels on the Space Shuttle were built by us. Since then, we have designed and developed over 80 configurations of high-performance, filament-wound pressure vessels, using liners of aluminum, steel, titanium, Inconel®, plastic, and rubber with structural laminates using a variety of fiber and resin combinations. Our products have also been used for aircraft emergency power, ejection systems, Skylab oxygen tanks, life raft inflation and breathing cylinders. Several patents, including one for a boss-to-liner interface for plastic-lined, high-pressure cylinders, distinguish Hexagon Lincoln as a leader in the composite pressure vessel field. We were the first manufacturer to qualify a pressure vessel for certification to the ASME Code, Section X in 1977 and the first manufacturer to certify an all-composite Natural Gas Vehicle (NGV) container to the ANSI/CSA NGV2 standard.
