Scuba cylinder, 4500psi pressure, Seamless gas cylinder, Composite cylinder, Carbon fiber tank, breathing air cylinder

Aluminum cylinder wrapped carbon fiber, 3L Carbon fiber tank, breathing air cylinder Carbon fiber cylinder  liners are made of high quality 6061 aluminum alloy materials. The manufacturing procedure includes punching, drawing, heat treatment, CNC flow forming spinning and inner surface treatment, etc. The wall thickness is uniform with little difference. The shape of shoulder and base are produced with high precision and consistency. Anodic oxidation treatment gives the inner surface better corrosion resistance performance. Cylinder winding layers are made of imported superior quality carbon fibers, epoxy and other materials and are manufactured through the procedures of CNC winding, high temperature curing, etc.   Full-wrapped Composite Gas Cylinders Most compact, lightest-weight cylinders available up to 70 percent lighter than steel cylinders. Available in carbon-wrapped and fiberglass-wrapped models. Ideal for emergency medical applications. Wide range of sizes and capacities. Extremely durable, easy-care materials assure long cylinder life. Minimum burst pressure tested to more than 3 times service pressure without failure. Manufactured to all recognized international standards.
