Custom D.O.T. Composite High Pressure Cylinders

 

BAC is an approved and registered pressure vessel manufacturer with the U.S. Department of Transportation (D.O.T.). Our Registration Number is M5324. Our vast knowledge of a variety of composite materials allows us to design and fabricate pressure vessels with aluminum liners and a variety of composite material overwraps (in an epoxy resin) including:

  •    fiberglass

  •    aramid (Kevlar®)

  •    carbon fiber

In addition, we offer high pressure designs using thermoplastic liner materials and other super alloys.

 

Why BAC Composite D.O.T. Cylinders?

1. EXPERIENCE

BAC's engineering staff has over 27 years of design, analysis, testing and manufacturing experience of all types of composite pressure vessels in compliance with D.O.T. specifications.

 

2. CUTTING EDGE - We Set the Standard in D.O.T. Composite Cylinder Design

Lightest Weight

BAC's composite cylinder designs are the lightest weight, highest performance composite pressure vessels available.  We use the latest in composite materials technology along with the highest performance automated manufacturing techniques.  This results in the highest strength per cross-sectional area laminate material properties in combination with long-establish proven analysis techniques. 

1st D.O.T. 5 Year Retest

In addition to the lightest weight vessel design, BAC pioneered the first composite cylinder to receive the 5 year retest (vs. 3 year) from D.O.T.  

1st D.O.T. Extended Life Composite Cylinder Program

BAC also, working with D.O.T., pioneered the "One and Only" extended life composite cylinder program. If you're tired of drilling holes in your current composite cylinders after 15 years and throwing them away and you need extended life cylinders, let us know.

 

3. CUSTOM COMPOSITE CYLINDER DESIGN

While we do not offer a large variety of "Vanilla" type, off-the-shelf composite high pressure cylinders, we do specialize in working with our customers from a "clean sheet of paper" concept to design the very best, highest performance, lightest weight, pressure vessel to meet your specific requirements.

 

The BAC K12 cylinder pictured here is one example of a custom composite cylinder specifically designed for the medical oxygen EMS market.

  • 12 cu. ft. of Oxygen
  • Weighs ONLY 2.0 lbs. at 0 psig
  • Diameter: 4.33" (Same as Alum. "D")
  • Height: 11.20" (w/o valve)
  • Service Pressure: 2650 psig
  • Min. Burst Pressure: 9275 psig
