oxy tank feels full??

[e-jipt]

My tanks still feels full. Using a liquid tank. It's still pretty heavy and when I shake it the big thing inside goes clunk clunk clunk!!
Isn't that frozen oxy?
My last two tanks I didn't hear anything when I shook them and they were empty. I know the guages at the top don't really work.
Anyway I was working and my oxy went out. I thought maybe it was the pressure reg so I turned it up, and up some more but I swear it's acting like I'm out of oxy. But my liquid tank feels at least half full to me.
Any ideas?
:bangHead:

what does the pressure on the tank say? You may need to turn the pressure builder on on the tank and let the pressure build up to a usable level. If your reg is set at say 40 your tank needs to be at at least 40, prob 60 or higher would be best. My tank usually sits at 100-150.

[e-jipt]

the gauge on the tank is reading 0 psi...
is there something I can do to change that? did I do something to cause that cuz I swear I don't think it's empty. =p

[petto]

There is a pressure building valve on the oxy tank. Turn it open and if the tank is NOT empty the pressure will build back up. Once it gets to 100-150 turn the pressure builder off. I have had tanks before where I had to build the pressure every day. If this is the case let your oxy co know when they pick it up and they can fix it. Not a big deal, just a hassle. If the pressure does not build then your tank is prob empty.

excuse the noobness but I've only had liquid for about 3 months and I've never had this problem :o:

not sure which valve to turn on but there's only a few and seeing as most of them are for hooking stuff up to, and only one valve is hooked up to the tank I'm think that's the one I turn, here's a pic tell me if I'm right.

Turned it on but haven't noticed anything, guess I'll call the oxy company and see what they think. Thanks so much for the help :D

Yes, the one that feeds back into the tank is the pressure builder valve. The other 2 are for fill and venting. The last one is for use.

[Alfred]

Yes that is the pressure builder valve.Doubt seriously that the "clunk clunk" sound is "frozen oxygen" btw.

[petto]

There is a mechanism of sorts in the tank. That I believe is the "clunk". Thats why you are not supposed to lay them on there side.

[e-jipt]

Yea I'm not sure what the clunk is, assumed either frozen o2 or some type of aggitator? But I've had 2 empty tanks before they feel a lot more lighter then this.
I turned on the pressure builder valve with no luck, maybe it is empty who knows?
calling the company now, but still don't think it's empty, haven't had it too long and it's heavier then I remember.

how long have u had it what type of torch how many hours of torch time, any venting? all tanks are different.

[e-jipt]

well the dude on the phone thinks that it's empty. Got another one coming which really sucks, I think I've only had this tank two weeks I swear something's wrong but maybe I'm just tripping. Doing the same ammount of work on the same torch so I don't see what's up with it lasting 1/2 as long. Really sucks cuz I gotta pay for the new tank with the money that was supposed to be paying off my torch.
Now I'm 2 months behind on rent and other bills and haven't grocery shopped in over 2 months either, and still owe 600 to the credit cards that should have been paid off this month... dammit

:bangHead::bangHead:

I'm using a pm2d, about 20 to 30 hours a week. yes it seems to vent a lot when I use it, but not much at all when I'm not torching. This tank was covered in frost everytime I used it up near the valves.

btw he said that clunk clunk is a magnet inside the tank.

[FredLight]

Hey e-jipt, something sounds backwards about that venting situation. Shouldn't it only vent when you're not using it?

Are you sure you're turning the right knob?

Seems weird.

[Gibsons Glassworks]

venting is only suposed to happed if you dont work for long enough for the pressure to build past the vent pressure usually aorund 300?

When new tank shows up you may want to have driver/delivery person give you a little tour of the tank valves and what they do and how to read gauges in comparison to what pressure builder valve does....

Though there is a lot of good knowledge here, its not like having a person right in front of you that can respond specifically to what you need to know... Sometimes meaning gets a little lost through interpretation of written words over distance....

well the only valve I usally use is the valve with my regulator on it. and yes it's most definitely venting when I use it and getting frosty. No venting so much when I'm not using it but some days i've heard it vent. I can't remember if the first tank I had vented when I used it, I was only working on a national waiting for my big torch. But I know the last two vent when I torch.
Is that not supposed to happen? the guy should be here any minute with the new tank.
I'm sure I turned on the pressure builder valve yesterday, it had a tag on it that says "P.B." the guy on the phone said that was right. But yea, I'll still get that guy to fill me in on any details I might be missing.
Thanks for the replies guys :D
:chilling:

Edit:
me and my inablity to tell time over long distances. I swear it felt like I'd just gotten a tank 2-3 weeks ago, but getting the date from the company it's been a bit longer then I thought. I'm going to start keeping these dates written down when I order new tanks. I just thought it felt too heavy still to be empty. or maybe I just really wanted it to still have gas...

[e-jipt]

I usally don't take more then a day, maybe two away from torching. And it's not really hot here anymore (central va)

[e-jipt]

Ok, I just got my tank. I talked to the guy about it. He told me what everything did which I pretty much knew. The on tank pressure gauge and what not, the p.b. valve which jonas told me about yesterday.
Anyway he said the tank is set at about 230ish psi and it'll vent if it goes over that. If I'm not pulling enough pressure off the tank when I'm work it might vent but I'm pretty sure I'm pulling off enough, especially sometimes my girls works on my national that's hooked up. He said it *should* vent when I'm not working or if it gets kinda hot outside. He told me maybe the tank was acting up and if it kept venting while I was working to let him know.
Anybody else have tanks that vent while they work but they're using a big torch or multiple people working?

[mer]

it might vent at first until you use enough gas to drop the pressure below the 230. if it vents all the time it might just be too much for you. you could consider going back to k-tanks.

[Snurf]

my last tank was venting constantly, I called the oxy company up 4 days after delivery and they replaced the tank the next day....the new tank is way better.

I told them that i have gotten 15 tanks from this supplyer and this tank was un-acceptable....sometimes i think that they want to give us the bunk tanks to sell more product.

I hooked up the delivery driver with some glass ornaments when he brought the replacement tank.

[Alfred]

See if they'll give you one with a 350-500psi pressure valve

[e-jipt]

cool, I'll see how this new tank goes :chilling:

[skip]

I have a trick for you. Take your shoe off lift the tank up. Stick your foot under the tank and let it down. If it hurts your a pussy.
