Quite an unusual one..... We have to convert a number of 40ft open top containers to store water which were initially designed for semi wet earth. The top of the container has an existing 75 x 75 x 8mm H.S welded all the way top of the container and 3nos. same sized sections welded vertically...

JStephen..... If I am to submit the calculations to my client could I recommend anchor bolts to suit app F even though they are not required in 5.11?

I have been running some calculations for a tank with a design internal pressure of 7.5mbar and a 90mph wind speed. According to section 5.11 the tank does not require anchor bolts however when I do calculation F 4.2 - Pmax is less than my design pressure. The roof to shell compression area is...

Dear All, This is probably not the best forum to be posting this question on but it is related to tank design so here goes.... I need to do calculations to determine the insulation thickness on a storage tank and need to get the heat transfer coefficient (U). Where can I obtain this...

MATI22.... Sounds like an excellent idea but how do you secure the cladding?

I have a storage tank in service that is to be converted to heated and insulated. The owner of the tank wants to minimise the down time by doing all insulation works whilst the tank is still in service. Can anyone offer a solution as to how we can attach the insulation brackets onto the tank...

Once you have calculated the total inbreathing and outbreathing of the tank how do you then determine what size vent you should use if you are using a open swan neck breather.

If there is slight pitting due to corrosion on a tank shell is it acceptable to fill in with welding?

Does anybody have any excel spreadsheets for the calculations in API 653 appendix B they would be willing to share? This would be greatly appreciated if somebody could help!

Has anybody ever heard of a foam pourer being inserted through the roof of an API 650 built storage tank?

Thanks. However I do not have NFPA 30 and need the information asap. Is there any chance you could please advise on my 2 requirements. Would be much appreciated.

Can someone please tell me the spacing requirements in a depot between 2 storage tanks and also between a storage tank and bund wall.

Does anybody know where I might be able to find information and maybe even cost estimates on "Nitrogen Tank Blanketing". I have checked a few websites but cannot seem to find anything that informative.

Has anybody designed/fabricated an open top storage tank with a steel grill in place of the roof. I want to use 16mm round bar in mesh form but will face the obvious problem of it sagging (tank diameter at 11.5m). My other thoughts were to have just a couple of roof rafters on which the round...

Dear All, In terms of safety in a fuel depot is there a minimum distance the offices should away from the fire fighting pump house (assuming pump controls are in pump house) and the loading and offloading gantry's? Thanks

We have just begun a piping job where the client has stipulated that all pipes 2" and below are to be TIG welded regardless of what the pipe is carrying. Can somebody tell me why this may be?

No... Is post heat a requirement with E7018?

I have a quick question. I have only encountered jobs (tank building) where the shell plates are to be built using a E6010 filler and E6013 cap which has proved to be easy to use in the past. I am now working on a job where the client is demanding we use E7018 on the shell joints (root and...

Does this now mean that "wl" merely replaces "wa" in the calculation from the earlier edition? Does Mf = (wl)*(Diameter)*(Pi)*(Radius)

Thanks IFR. Useful programme! Do you know of any such programmes for locations outside the USA?
