SOME’S GOOD, MORE’S BETTER & TOO MUCH IS DANGEROUS!

Posted under Uncategorized

Filling compressed gas cylinders is a serious matter. The Federal Government says that it’s illegal to fill gas cylinders beyond their rated fill pressures. Injuries at the fill station are common. Gas cylinder filling is a Hazmat situation that requires training for any individual who provides pressurized gas fills. Many divers want a “good fill” but what is a good fill? Divers seem to want their cylinders overpressurized meaning more than the cylinder is rated for. Cylinders are engineered & tested to allow for their maximum fill pressures. When cylinders get taken above their engineered max fill pressure things can go wrong. Cylinders will begin to weaken & potentially they will fail their hydrostatic test. It compromises the bust disc causing the burst disc to get bulged & then the burst disc can let go well below its rated burst pressure & at any given time (even U/W!) Most of our more discerning divers bring their cylinders in to fill well in advance so as to allow us to fill nice & slow, allow for cooling then to top up to the final psi while cooled.

IF IT’S TOO GOOD TO BE TRUE IT IS!

imageWe warned you in this post a year ago about miflex hoses. Now DAN (Divers Alert Network) posted a additional issue with these hoses. They allow for polymorphic crystallization corrosion on the inside constricting & potentially blocking the air flow. Cyclical heating & cooling at oil-water interfaces combined with the molecular structure of the internal tube lining promotes crystallization of these materials allowing growth to accumulate over time & that is just what’s happening inside! The external fiber woven sheath acts like a cheese grater. ┬áThe hose sheath fibers collect sand, soils & vegetation. These hoses fray & the plastic sheath fibers stick out & can stab you! What is wrong with rubber? They are stronger, last longer, flex as much & cost less.

Neptunes Robert, Mike & Bill scored this past weekend with some mighty fine large lobsters. These hunters do not waste any part of a Lobster. They eat the carapace meat as well as the tail. Never throw away the “head” of a fresh Lobster, it can be more work but worth all the effort with more flavor in the head than tail & the legs taste like crab legs!

imageHere is a piece of diving history! We recently serviced this Royal Aqualung DA Aquamaster double hose regulator for David Knight. It now works better than new. Something to consider for photo as the exhaust bubbles are out the back plus the retro cool factor is over the top!
