An aluminum liner enables tank to hold 15% to 25% more fuel, which means solid waste collection routes can be extended.

Worthington Industries, Inc. announced today that it has expanded its line of compressed natural gas (CNG) cylinders with a new lightweight, large diameter, 26.2- inch model. The new large diameter cylinder was introduced today at the 2015 Alternative Clean Transportation (ACT) Expo in Dallas.

This is the Company’s largest Type III CNG cylinder and provides superior fast-fill efficiency. The inner aluminum liner dissipates heat during fast-filling allowing for an additional 15 to 25 percent more fuel storage compared to Type IV cylinders of similar size.

Ideal for Class 8 heavy-duty and refuse trucks, these large diameter cylinders will fill to rated capacity making longer routes possible. As with all Worthington Type III cylinders, the aluminum inner liner provides an added safety feature, by reducing the risk of flex or fracture in the outer composite reinforcement if an impact occurs.

“We believe that the fast-fill efficiency and durability of our new large diameter cylinder will be a welcomed addition to the market, maximizing the fuel system design for original equipment manufacturers,” said Wayne Powers, General Manager of Worthington Industries’ Alternative Fuels business. “Our 30 years of experience producing cylinders which safely and efficiently store and transport alternative fuels has made us a trusted name in CNG cylinders. Of the hundreds of thousands of cylinders Worthington has produced for alternative-fuel applications globally, we have never had a composite cylinder failure.

” Worthington Type III CNG cylinders, including the new large diameter model, are built to aircraft, railcar and watercraft CNG cylinder standards, which are more stringent than typical over-the-road standards. Worthington’s testing requires a minimum burst safety factor of 3.0 times the rated pressure, along with sidewall structure impact testing. The U.S. National Highway Traffic Safety Administration (NHTSA) Federal Motor Vehicle Safety Standard (FMVSS) 304 standard, requires a minimum CNG cylinder burst safety factor of 2.25 times the rated pressure and does not require sidewall structure impact testing. Worthington’s new large diameter cylinder is also certified with the American National Standards Institute (ANSI)/Canadian Standards Association (CSA) NGV2 standard.

Worthington’s new Type III CNG cylinder features gas-tight construction thanks to its inner aluminum liner, which prevents permeation. There are also no filling restrictions in hot or cold weather. The aluminum liner also provides better heat tolerance in the event of a fire, and transfers heat to the pressure relief device.
