In today's video, Instructor Trainer Bryan Stafford is performing several Visual Inspections, and comes across a 1973 Steel 72, that looks brand new on the inside. As he states in the video, "If we take good care of our gear, it will take good care of us!"

These are great videos Brian, super informative. thanks for posting, not easy to get clear images inside a tank.

[@LakeHickoryScuba]

Glad you liked the video Jeffrey Donnelly.

[@aurnbob7209]

was watching Deep Water Salvage last night and there you were. Enjoyed.

[@LakeHickoryScuba]

Glad you liked the episoide AU RNBOB, we had fun filming for the season finale. We are hoping they will renew for season 3.

Nice to see but would have been helpful if you had described what we can do to help keep our cylinders in good condition.

[@LakeHickoryScuba]

Hello Elaine Morgan, these are the things we discuss during the SSI Equipment Techniques Course. The main things you will want to do is prevent the cylinders from becoming damaged by dropping them. You will also want to keep any and all moisture from getting inside the cylinder. And lastly, keep the cylinder serviced when its time for a visual inspection and hydrostatic testing. Hope this helps.

I take really good care of my steel cylinders, but I’ve been screwed by some wet air fills recently that caused some rusting. It’s so frustrating !

[@LakeHickoryScuba]

Hello Judson Holt, sorry to hear about your wet fills. Specifically with DIN Valves, I will always purge the valve orifice prior to attaching our fill whips. Another great option is to simply dry off the valve with a rag before filling.

Hey Brian, Another good video. Wonder you could do a quick video on the number marking on the outside of the tank. I last learnt on my open water. Forgotten how to read it the info. Which would useful travelling to tropic dive sites. Thanks

[@LakeHickoryScuba]

Hello Allen Gavin, I will be happy to make a video about tank markings. We currently have videos scheduled to the end of September, so stay tuned.
Here is a quick refresher for you. The current cylinder I have in front of me reads as follows.
DOT-3AL3000 CC681195 M5659 04 22 MI XS-80 TC-3ALM207
DOT-3AL3000 and the TC-3ALM207 simply tells us the the USDOT and Transport Canada have authority of how the cylinder is transported.
CC681195 is the Serial Number on
M5659 and MI tells us who the cylinder is manufactured by, in this case Metal Impact
04 22 tells us the born on date of the cylinder April 2022
XS-80 tells us the distributer and the size of the cylinder XS Scuba and 80 cubic foot.
Hope this helps.

@@LakeHickoryScuba Thanks Bryan. very informative. Especially, If you are looking at purchasing a used cylinder tank or diving somewhere tropical/exotic. Keep with the great work. Safe diving.

What constitutes "taking good care of your cylinders?" I've heard for the last 4 years I've been diving that cylinders will last a long time if you take care of them. But nobody has said exactly what that means. Aside from where you get your air from, and not letting them drain to 0psi, letting water in them, what else are we talking about? You mentioned tanks laying on their side. I wouldn't think that would make a difference in wear and tear on a tank, would it? I, personally, live in Michigan, and for example, we dove this last weekend in Lake Huron. (video of the bottom portion of one of the dives can be found here, if you are interested: czcams.com/video/uaF57mvH7RI/video.html) Air temp on the surface was around 85F. Temp at depth was around 41F. Could this temperature differential be a cause for shorter tank life? As you cool the tank, any moisture in there will condense. Lots of possibilities, I know, but can you elaborate, or do a "deep dive" on what constitutes good care of tanks? Thank you for the content! Keep up the good work!

Hello MahnkeMachine. In short, taking good care of your cylinders means preventing damage to them by not dropping them, securing them when not in use, maintaining them when it comes to visual inspections and hydro static testing. Typically, storing steel cylinders on their sides for a lengthy period of time is frowned upon, as the thinnest layer of metal on a cylinder is its sidewall. In the event moisture does enter the cylinder (even by condensation), if it settles on the sidewall, it can corrode it very quickly. Also, not over pressurizing them during the filling process. I know this is one I struggle with personally, as do a lot of experienced divers and experience professionals. The thought process is, if the cylinder is hydro tested at 5/3rds the working pressure, then why must we only fill it to the working pressure stamp on the side. Well over time, you will wear out the elasticity of the metal in the threads (both steel and aluminum), thus shortening the lifespan of the cylinder. In the SSI Equipment Techniques Course, we teach several ways to prolong the life of your cylinder and the rest of your equipment as well. Hope this answers your questions.
