Worthington for CNG Tanks, Rigs
“Worthington offers the only fully integrated CNG fuel system in the industry for heavy duty trucks,” says alt fuels GM Wayne Powers. With last year’s acquisition of dHybrid, Worthington offers a full selection of CNG fuel systems, as well as fuel cylinders.
The CNG line-up includes back-of-cab, rail-mount, top-of-body and canopy designs, as well as tail-gate assemblies.
Worthington is close to final certification – it’s expected late in June – of a new line of 26.2-inch-diameter Type III carbon fiber-on-aluminum CNG cylinders. Depending on the fill situation, they can hold 15% to 25% more natural gas than competing tanks, Powers says.
Worthington offers propane autogas fuel tanks, too – more than 1,000 variations, manufactured in Jefferson, Ohio and in Slupsk, Poland. All are made of welded steel, and all x-rayed for quality prior to shipping, Powers says.
Worthington continues to emphasize CNG cylinder safety. The industry is “averaging two cylinder rupture events a year right now, and people should be made aware of it,” says product line manager John Coursen, citing the greater number of NGVs in service and aging equipment.
Coursen argues that fuel vessels for natural gas vehicles should meet the same standards of safety required for other transportation modes, such as aircraft and ships and rail. That means testing to three-times service pressure instead of the factor of 2.25 now required. Worthington also advocates a drop test to better gauge impact resistance.
