I have stopped hydro testing the Worthington's SP14157 and the 3AA galvanize. They are all failing, everyone of them.

The factory knows very well about this problem. Worthington is trying to skirt the problem. making it a warranty issue and throwing it onto the retesters and their customers. This needs to be a full recall issue. Worthington needs to pull all of these back in and do their own testing and stop trying to dump the problem on the retesters and Worthington customers.

Worthington tried to skirt the problem by putting out this tech bulletin saying we need to pre-stress the tank two times. That in its self is a dodge of the problem. The only other steel tank manufacture that has a pre-stress for their steel tank is PST (E9791) and they closed in 2005 because of that problem and it is the same as this problem with Worthington’s now. Taylor Wharton, Faber, Coyne, Asahi, Norris, etc. all of these steel tank manufactures do not have a special test protocol for their tanks. Asahi makes a galvanized tank and there is no pre-test and no problems testing them. They test very well with no pre-test.

Worthington has asked the DOT to change the test protocol from the expansion method to test by REE. I’m not going to get into explaining the differents in that. But that’s a dodge again from correcting the problem. I believe that DOT will change the test protocol for the SP14157, but I do not see how they can do much with the 3AA. Some experts (I have talked to some of my big dogs in the industry) in the hydro industry say that the 3AA can be changed. Time will tell?

To the lawyers on this board, you might want to look into a class action on this. Its time Worthington steeps up.

We have been working long, long hours for sport season, got to crash, will try to get back on SB later. Bye
 
To a very crude approximation, drag increases with cross-section (i.e., the diameter of your tanks) and decreases slightly with increasing length. If the tanks are equally as wide the larger tanks will give you more air and slightly less drag, so long as they don't impede your kicks or get in the way when gearing up.

I wish that I had some!
 
The Worthington's SP14157 DOT permit was renewed, here: http://www.ctcseminars.com/files/updates/Special Permits/SP 14157.pdf

Rick Christ, are you saying that in spite of the special tests, that the cylinders are STILL failing hydro? After the two pressurizations to 89% test pressure and then to test pressure?
Yes

Page 11 of the SP14157:
in accordance with § 180.209 as prescribed for DOT-3AA cylinders.

We still have to test by expansion method , special permit has not been changed yet.
got to go to bed, we will be testing all day tomorrow. Bye
