Wiretough Cylinders LLC manufacturers wire wrapped high pressure cylinders for the storage of a wide variety of gases, including compressed natural gas (CNG) on board a vehicle as fuel. The company additionally has developed cylinders in 200 to 875 Bar (3,000 to 13,000 psi) for storage of gases such as CNG, hydrogen, breathing air and helium. WireTough delivers the highest impact strength in the class of light weight fiber reinforced cylinders. This breakthrough is the result of WireTough's innovative production technology, where lightweight steel liners are wrapped with a proprietary very high strength steel wire, sealed with a special epoxy and covered with a protective mesh. Due to good thermal properties Wiretough Type II can hold 20-30% more CNG under fast fill than Type IV. It is 20% lighter than all steel Type I. Subjected to the rigorous NGV-2 tests, WireTough tanks meet ANSI-NGV-2-2007 and US-DOT requirements. Our tank design meets ASME Section VIII Division 3 requirements. The technology is under US patent applications and is now being expanded to 13,000 psi (875 Bar) tanks for storage of hydrogen for Fuel Cell vehicles. The company has recently received a funding from US Department of Energy to develop 13,000 psi (875 Bar) hydrogen storage vessel for the Fuel Cell industry.
