Any type of cylinder manufactured from 6351 alloy could conceivably develop a sustained-load crack over time if subjected to certain conditions.

Out of a total population of approximately 1,073,000 Luxfer scuba cylinders made of 6351 alloy, only 1.25% have exhibited SLC.

Very slowly, as extensive research by Luxfer and outside laboratories has shown.

SLC is a metallurgical phenomenon that occasionally develops in cylinders made of 6351 aluminum alloy, as well as in other types of pressure vessels and structural components under stress for sustained periods of time.

All composite cylinders have a 15-year service life in accordance with regulations around the world. In the United States, the service life is set by the U.S. Department of Transportation.

Luxfer's carbon composite cylinders must be retested (i.e., requalified for continued service) every five years, the same as aluminum oxygen cylinders.

Luxfer's carbon composite cylinders do not need any special handling equipment-in fact, they are the strongest, most durable cylinders ever made.

Luxfer's medical composite cylinders take standard valves and regulators.

Luxfer carbon composite cylinders are a profitable, cost-effective alternative to more expensive LOX systems because Luxfer composite cylinders allow you to leverage your existing filling and delivery equipment. Unlike LOX, composite cylinders do not require major investments in equipment and infrastructure. Moreover, since carbon composite cylinders cost less initially than LOX systems, you will recoup your initial investment and start getting your payback in far less time.

Getting your company involved with composite cylinder technology in the early stages will give you the opportunity to differentiate your company from your competitors and take advantage of growing referrals from medical prescribers in your area.

Carbon composite cylinder technology provides significant clinical benefits to patients, especially those who are ambulatory. Physicians often encourage ambulation for oxygen patients, and cylinder weight is an important factor in a patient's ability to remain active. Luxfer carbon composite cylinders are the lightest-weight portable oxygen cylinders available in the market today, which makes them an ideal choice for ambulatory patients.

Absolutely not. Oxygen-related fires are extremely rare events, which is a testimony not only to the safety and suitability of aluminum cylinders for oxygen service, but also to proper cleanliness, care and maintenance.
