E6498 Cylinder Hydro Markings

[Scared Silly]

OP-


Please check your pm's...I have a clarification on the issue.

Thanks

Please fill the rest of us in … As I too would like to know what the + stamping does in terms of future requals.

For the OP regarding the shop that failed to do the complete requal as well as missing the 3Al stamping. I'll send them a note, I have contacted several shops in the past. BTW not sure if you saw this thread I started a while ago to help educate folks: http://www.scubaboard.com/forums/ta...438-what-wrong-requalification-aka-hydro.html. The DM's cylinder ups the ante with the plus. Never seen that on an aluminum cylinder.

Interesting....obviously another case of *cough cough* " "under trained" hydro tester...

My understanding is...
1) Page 39, 5th Edition PSI Inspecting Cylinders, High and Gresham.... *note* Between paragraph 2 and paragraph 3 ...and I quote the text...
[NOTE]: Aluminum cylinders never qualify for a (+) and any aluminum cylinder bearing a (+) must be removed from service.
2) This cylinder was born in Nov of 1981... it is a Luxfer cylinder as shown by the original hydro stamp (Vertical arrow). It is also suspect alloy (6498) due to the lead content of the original alloy. Luxfer recommends an Visual Plus 3 Eddy Current test to check for SLC issues at every hydro for this tank series. Ref Inspecting Cylinders, 5th edition, High and Gresham, PSI, pgs 76-77

3) This cylinder is incorrectly/mismarked according to CFR 49...due to the lack of correct 3AL marking at prior/latest hydro re-test...and more importantly...the "+" stamp is illegal under CFR 49.

I hate to be that guy..BUT...your cylinder has/is an incorrect, illegal hydro certification, and SHOULD have been condemned...NOT "rejected"..condemned...and removed from service by the hydro facility.

Pg 86, PSI Inspecting Cylinders, 5th Edition states... 3rd paragraph...

Title 49 states that CONDEMN means a determination that a cylinder is unserviceable for the continued transportation of hazardous materials in commerce and that the cylinder may not be restored by repair, rebuilding, requalification or any other procedure.

Sorry...I know I seem hardcase, but it isn't worth it. It's a freakin cylinder.

And OP...hate to tell ya..but as an Instructor if something WERE to go south...your as liable as the shop owner. I wouldn't fill that thing under any circumstances...

Hope ya do the right thing, and I hope your DM understands WHY...

Best of luck-

What applicable CGA pamphlets do the above quoted guidelines appear in?

Many scuba tanks are stamped with excess information. Only problem seems to be when required information is missing or out of date.
