    Lightbulb carbon fiber bottles

    I'm looking for statistics on the benefits of carbon fiber bottles. Anyone know where I can look?

    from the Scott health and safety website.

    http://www.scotthealthsafety.com/PDF..._6319B_303.pdf

    The 2216 Aluminum cylinders weigh 21.0 lbs
    2216 Carbon Cylinder weighs 9.4 lbs.

    so the obvious answer is weight.

    Some of the other points are that the cylinders must be hydrostatically tested every 5 years. And, they have a life expectancy of 15 years.

    Just to clarify a bit, the aluminum bottles have to be tested every 5 years and the carbon fiber's have to be tested every 3 years. I also thought that the life was 15 years on aluminum bottles, but from what I've been told is they can stay in service as long as they pass the tests and there's not any damage that could compromise the bottle.

    Just to clarify a bit, the carbon fibers that were last hydrotested (or made) after July 1, 2001 (or was it 2000?) have to be hydrotested every 5 years. Cylinders before that and kevlar cylinders have to be every 3.

    Thanks for the info. on the testing. I've never heard that. Do you have any info. on the 15 year life for aluminum bottles, or can they stay in service as long as they pass hydro?

    All aluminum and steel bottles can stay in service as long as they pass the hydro test.

    Carbon fibers made before July '01 (or was it '00? I can't recall either) may be able to be tested every five years depending on the mfg. They had to have had their next due 3-year test first though.

    I know the Luxfers and SCI's that Scott uses fall into the 5 year category.

    The carbon fiber bottles have a 5 yr hydro requirement. Fiberglass hoop wound bottles have the 3 yr hydro testing requirement.
