Titan Series
Large Type III Pressure Vessels
High-capacity composite pressure vessels engineered for gas transport, ground storage and industrial systems where weight, durability and packaging efficiency matter.
Titan Series vessels combine aluminum liners with carbon-composite structural reinforcement to provide large-volume, high-pressure storage for hydrogen, breathing air, nitrogen, helium, argon and other compatible gases.
Large-volume composite gas storage
Built for stationary and mobile high-pressure systems.
Steelhead's large composite pressure vessels are designed to reduce system weight while supporting demanding gas-transport and storage applications.
Titan Series platforms can be integrated as single vessels or as part of bundled systems, MEGCs, tank farms and buffer-storage installations.

Titan Series · 5000 PSI Family
Five standard capacities on a 17-inch OD Type III platform.
Steelhead's 5000 PSI Type III COPV family provides large-volume, high-pressure gas storage in five standard capacities from 90 to 270 liters, all using a common 17-inch outside diameter.
The family is designed for mobile gas transport, bundled systems and MEGCs, as well as stationary tank farms and buffer-storage applications.
5000 PSI vessel configurations
All five standard configurations share the same nominal 432 mm (17 in) outside diameter.
