CNG Tanks

US-DOT Approved Tanks 

CNG of OKC is proud to partner with the nations finest CNG cylinder manufacturers to supply our customers with the highest quality tanks, at the lowest prices.

Types of CNG Tanks

Type 1- All metal (aluminum or steel). Cheap but heavy.  Can cause vehicle sagging in smaller vehicles.

Type 2 - Metal liner reinforced by composite wrap (glass or carbon fiber) around middle (“hoop wrapped”).  Liner takes 50% and composite takes 50% of the stress caused by internal pressurization. Less heavy, but slightly higher cost over Type 1 cylinders.

Type 3 - Aluminum liner reinforced by composite wrap around entire tank (“full wrapped”).  Liner takes small amount of the stress.  Light-weight, but expensive.

Type 4 -Plastic gas-tight liner reinforced by composite wrap around entire tank (“full wrapped”).  Entire strength of tank is composite reinforcement.  Light-weight, but higher priced.
