Steelhead’s engineers harnessed the advanced material benefits of carbonfiber and introduced them to the traditionally heavy field of hydraulics. Lighter, stronger, simpler (and much more attractive), Steelhead has removed 86% of the mass from a traditional diaphragm accumulator with a patented thin-walled shell reinforced with composites. At Steelhead Composites, we have reinforced all types of […]
Steelhead Composites recently achieved ISO 14001:2015 environmental certification. Why was this important to your company? What did you have to do to earn this designation? How long a process is it? The foundation of Steelhead was founded on designing and producing products that change the world for the better and make a positive impact. Environmental […]
Since a compsite overwrapped pressure vessel (COPV) stores gas at high pressure, the design of the vessel structure needs to be treated as fracture critical. This means that the design calculations and tests need to verify that the vessel will not fail catastrophically during its intended life span. During its service life, the COPV is […]
“What certification do I need?” This is one of the most common inquiries Steelhead Composites receives from customers…and it’s not a simple question to answer. The regulatory framework surrounding pressure vessels is multifaceted and overwhelming. Add on the additional complexities of industry standards, local jurisdictions and insurance companies, and one can quickly get lost in […]
Introducing Steelhead’s lightweight, low cost, simple and safe propellant concept SECTION 1: BACKGROUND A common design for launch/space (i.e., rocket) propulsion involves liquid propellants. In this application, often there is a gaseous pressurant stored in a Composite Overwrapped Pressure Vessel (COPV) at high pressure, and a diaphragm tank for the propellant. These diaphragm vessels […]
Andrew Coors and Marisa Veni Sundy will be at HANNOVER MESSE again this year. What days will you be walking the show?
Small misunderstanding with bring your kid to work day. Don’t worry, Andrew Coors has it under control. #notkidding #goatbaby
Steelhead Compositesmakes bottles/liners/cylinders with a process called metal spinning or spin forming, a hot forming process that rotates a metal tube around its central axis (similar to a lathe), softens the material by adding adequate heat, and then forms the material to its final shape using a roller. Our spinforming process begins with an extruded […]
Steelhead is supporting the growing #hydrogen ecosystem with these beautiful 270L high pressure cylinders for gas transport and #fuelcell use. While these three are part of our certification efforts, future vessels will find a home in zero-emission fueling applications in transit, rail, marine, aerospace or stationary storage. At 350 bar operating pressure, these vessels will […]
Steelhead Composites tested some new dome designs on seamless stainless steel last week. The forming takes place at 1150 C – 1250 C (2,100 F – 2,300 F) — a truly jaw-dropping temperature. This is >3x the requirement for forming domes on our aluminum cylinders. The color striations of each pass during the formation was […]
