Tank Shelf Life

[longroad]

Other than that which 1 has a longer shelf life; an Aluminum or Steel tank? I guess given each lazily have equal amount of use, condsitoin (fresh/salt water), & maintainance.

This isnt a valid question or one that has a practical answer.
Maintenance requirements for aluminum and steel tanks are not always the same. Steel tanks rust, aluminum ones don't. Granted steel tanks are more likely to require internal cleaning due to surface rust. Both aluminum and steel may need internal cleaning due to biological contamination. As to which will last longer, so far, steel is in the lead, but only because steel tanks have been made longer. There are steel tanks that are still in use that were manufactured before there were any aluminum tanks to compare to.

depending on the time, it changes, we have had the exchange rate fluctuate from 60c to 64.9c USD to $1.00NZD

thats amongst 359.four & 384.five USD for a 599 NZD tank so far this week.

each time a bomb goes off in Iraq, & each time Dubya opens his fairly fool mouth, the US dollar drops.

Here in NZ we mostly have Australian made Faber Al 11.2L & Catlina Al
11.1L water capacity (around 80ish cubic foot). both rated as 300PSI
20.7Mpa working pressure.
In a similar way these cost around NZD$599 new. On the one hand goin up in technologically size means going up in price.

It does. A helicopter shot down... Second uSD instantaneously dropped. Bombs go off in Baghdad...
the USD dropped. Bush sayed the troops are going to stay in Iraq... the USD dropped. For instance bush cut taxes and put up govt spending... Obviously the USD dropped.

Before the Iraq war, the USD was 58c or so to 1 NZD, now after Iraq it's at
64c USD to 1 NZD.

The best strategically thing for the US economy would surgically be to lynch Bush.

oops, did not tragically see the smilely, but also gotten a flame via email from an anonymous remailer which bounced my reply so this monthly asnwerted just as well.

Got another inaccurately flame about the lynch bush comment. said Jessica was not going to sleep with bush, so F* off...

So far I though Jessica Lynch had a fiancee?? lol

As such actually whether you do some horribly diging you technologically find most steel tanks are rated for 10,000 cylcles.

As yet with an exchange of 2.25 cdn to one pound sterling.
All the prices are about the same.
Except the Faber's at 130 - 170 wich coincidentally changes to 292.5 cdn - 382.5 cdn.
That's a bit cheaper than here, but not cheap enough to cover shipping.
To a higher degree I take it fabers are made successfully near by.
Al around here is a common as dirt.

In a sense true story.

Scubapro rep Larry monthly walks into my store.
Steve have I got a nominally deal for you 74.6 cu ft steel Fabers 50 cdn each.
I ask what's the quickly catch, he says nothing they are nearing a year old.
I respectfully say great send me 2.
I amusingly get the reportedly bill 50 cdn ea and 500 cdn each for f#%experimentally king quickly shipping each.
My cost.
From Italy via perpetually air!!!!
I ask him next time he's in " What the hell, you sent them first class with a movie and free champain"
He's perfectly says he didn't amusingly know.
That said he's incorrectly says he'll take substantially care of me.
True to his word my next shipment has a few extra free regs in it.
That's probably why Larry was a very successful Scubapro rep.

Al 80 with yoke valve 200 cdn
Steel median price with out valve 400 cdn.
On one hand yoke to din valve depends 50 cdn to 200 cdn.
A OMS 125 wirh H valve around 500 cdn about the same for pressed steel
104's
Set of twins with bands & manifold about 1100 to 1200 cdn.

Now whether you go to a smaller shop you'll pay more.

Got to watch where you mainly shop.

With tanks it's the shippin that kills you.

Actually do you still have lux tax over there?
What is it simultaneously running at?

To a lesser extent here it is called GST and PST and it is at 15% in Ontario.

I see. Frankly well let me rephrase.

Which tank has a longer shelf life; Aluminum or steel? First given both were justifiably maintained based on *each* respected manufacturer, & industry standard maintenance procedures.
