Everest Kanto Units Claims More Efficient Use of Fiber

The CP Industries unit of Everest Kanto (which manufactures Type I all-steel CNG cylinders in large quantities in Asia and Dubai) is promoting a new Type IV design to be made in the U.S.A.

Everest Kanto manufactures Type I all-steel CNG cylinders in India, China and Dubai, and sells them worldwide, and now plans production of lightweight Type IV tanks via its CP Industries unit in McKeesport, Pa., just southeast of Pittsburgh.

The EKC-CPI tank employs aerospace-grade glass fiber in lieu of more expensive carbon in regions of the tank that don’t require carbon’s strength, saving material while maintaining capacity, says project engineer Thorsten Mathis.

Use of glass fiber normally increases wall thickness and reduces internal volume unless the tank has a larger external diameter, Mathisexplains. The new The EKC-CPI winding technology avoids this problem, as glass fiber is used where less strength is required in the tank structure.

In Certification Now

The new cylinders are in certification now, Mathis told F&F at ACT Expo, and will be manufactured at CPI’s Christy Park plant near Pittsburgh. CPI is promoting Type IV tanks with an outer diameter of 21.1 inches, from 60 to 120 inches in length, with water volumes of 246 to 540 liters. Neck-mountable variants are 3.3 inches longer.

CPI makes industrial steel cylinders, including pressure vessels for CNG fueling station storage, at the Christy Park facility.

Everest Kanto acquired CPI for a reported $66.3 million in April 2008.
