WireTough Cylinders LLC Home
WireTough Cylinders LLC has developed a proprietary, patented technology that produces very strong cylinders for a variety of uses. This new option for commercial storage of hydrogen, CNG or other industrial gases, is the result of WireTough’s innovative production technology. WireTough lightweight steel liners are wrapped with a very high strength steel wire, then sealed with a special epoxy and covered with a protective mesh. WireTough's patented technology produces stronger cylinders, is scale-able and can be used to produce units for a wide range of sizes, pressures and applications.
WireTough currently produces ASME cylinders for ground storage of hydrogen and CNG, as well as a line of DOT and NGV-2 compliant CNG vehicle cylinders. In 2014, The United States Department of Energy awarded WireTough a $2 million grant to develop “jumbo” cylinders for hydrogen storage at maximum workable storage of 15,000 psi (1,000 bar). These large (16 inches by up to 30 feet) ASME certified tanks will be marketed during the first quarter of 2017.
ASME has authorized WireTough to certify its' cylinders under Section VIII, Division 3, for the storage of gasses at pressures up to 15,000 psi. WireTough has also met the requirements of Section KD-10, which impose additional requirements for the storage of hydrogen. Additionally, the Virginia Tobacco Indemnification Commission awarded WireTough a $2 million dollar grant in 2015, to develop its ground storage products and manufacture them at a facility in Bristol, Virginia.
WireTough CNG vehicle cylinders are certified under both NGV-2 and DOT standards.
