Production of Cylinders for Heavy NGVs to Begin This Summer,
Firm Will Also Show ASME-Approved Toroidal Tanks for Propane
Worthington Industries has prepared a new line of large-diameter Type III compressed natural gas cylinders for debut at the ACT Expo show next week in Long Beach, Calif. Worthington plans production of four standard cylinder types, with custom sizes of 26-inch tanks to 120 inches in length. The firm will also debut a line of toroidal fuel tanks for propane autogas.
The new CNG cylinders have been in development since last year, with Worthington taking care to line up a reliable supply of 6061 aluminum tube before announcing availability. “We’ve identified and are working with a couple of suppliers,” says Worthington alternative fuels director Wayne Powers.
Type III CNG tanks are made with aluminum liners with a full carbon fiber overwrap.
Propane Behind Stako Buy
Worthington will show a 25-inch-diameter prototype, 55 inches in length with interior volume of approximately 300 liters, at ACT Expo.
The manufacturer will augment the 25/55 CNG cylinder with 26-inch tanks in standard lengths of 60, 80 and 90 inches, with volumes of 360, 510 and 585 liters, Powers told F&F.
The welded steel toroidal propane tanks come as a result of Worthington’s late-2011 acquisition of Poland’s Stako, which produced fuel vessels for propane vessel before branching to CNG (F&F, June 14, 2010).
An early version was shown at ACT Expo 2012. This year Worthington has ASME approval and a seven-size product line with capacities ranging from 15.9 to 32.2 gallons.
