Nickel Tank Design Standard?

[skearse]

All,

We are considering replacing a couple of our tanks that are on a 20 year replacement cycle with a nickel tank that will last indefinitely (at least, more than 20 years). Is anyone aware of any specific deisgn standards, codes, etc., that are specific to nickel? AMSE is applicable, but I was wondering if there was anything else out there.

Thanks!

Sorry; this is for an application in the US.

just get out a big checkbook

Yeah, but the way the price of nickel has been dropping over the past couple of months it may make some sense (cents?) in the long term.

If you are using pure nickel, (Nickel 200??) I am guessing that this is a hot caustic application.

I agree that this tank will certainly cost a lot of $$$$$$

Are you sure that this is an ASME design?

What are the max operating temp & pressure ?

What is the volume ?

Nope, not hot caustic. Combustible material, so we would prefer ASME design but not absolutely required (I originally thought it was flammable, in which case our internal reqwuirements are ASME 50 psi rating).

Operating T is ambient; P is for filling from tank truck & vacuum for pump out to process, so nothing crazy.

Small tank; ~12,000 gal.

Thanks!

I suggest that you consider a horizontal axis tank, about 8 foot diameter and 33 foot OAL.

I suggest two F&D heads, two saddle supports and have the tank designed, fabricated and tested to ASME VIII for about 30 psig (consider the cost and availabilty of the head materials when you specify the MAWP)

If your mysterious liquid is only "combustable" and not caustic or corrosive, I suggest that perhaps solid nickel may not be the cheapest choice for the service. Of what material is the tank on the truck made from ? I am willing to bet that the tanker truck is not a nickel container.

Consider nickel lined plate as an alternative.

Talk to your supplier and see what materials are used in his bulk storage facility.

The only time I have encountered pure nickel in process equipment design was in boiling caustic soda production.

Suppliers tank is nickel (which is why we are considering it). Cheap's not the issue, long term reliabilty is. We are currently using FRP (yeah, I don't know why I thought FRP would be code) and those are replaced on a 20-year basis. We are not married to Ni at this point, and plated/clad is an option as well; it's just an alternative that we are considering at this point.

Besides ASME (or other design codes that are "generic" in metallurgy), are there any that are specific to Ni?

IS THE TANK USED FOR LNG?

[skearse]

No. Sorry I can't be specific about the product; it's not hot caustic and it's not LNG.
