Help identifying a tank - Steel 90CU 3000 psi?

[Synblade]

Heya - I found a tank on a Craigslist ad that I'm thinking about picking up but I wanted to know if anyone had an idea on what it could be... The information I've been given hasn't helped me identify it yet.

Here's what I got from him:

The dimensions are 7 1/4" Diameter x 26 3/4" High.
It is an older tank. Purchased in early 1990's. Has not been in service for 12 years.
Still is holding pressure.
I'm not 100% sure, but I think it is a 90cf @ 3000#.
I know it carries a negative weight of between -6.5 to -6.8.
The weight is 40# plus.

There's always the risk it may fail hydro/vip but for a steel tank of that size he's only asking $40. What do you guys think about this? Any idea on what the tank could actually be?

It is a 96. Stupid heavy old tank. Weighs the same as a 104.

If you know you want the tank - I am assuming it is more than just a cheap tank that is driving your decision - tell him you will pay him to get the hydro and viz first then pickup the tank.

If the tank fails - you are only out the hydro and viz $$. You save yourself $40 and he should take it off the market.
If you buy it and it fails you are out the hydro, viz and $40...

That is what I think...

Interesting... I didn't know there were 96CU tanks, and 3000 is what, medium pressure?

I'll think about asking him to do the hydro/vip and going from there, I was really looking for a tank that was more in between my LP72's and LP 95... this may not fit the bill but it could be good to have another larger tank. Thanks for the responses!

3000 psi is rated pressure for that tank. You may want to hold off and ask a lot more questions if you are buying a tank... I am thinking you are just at the beginning of your learning curve...

In this case Google is your friend - if you need I can send you some links but I think you need to take a step back or your going to buy something you dont need or want...

Yeah after doing more research I'm going to stick with LP tanks. Thanks for the info.
