Tank Guru blog 
Very informative site…thanks!
Russell, just found your site and hope to gain a good deal of info. I have been dealing with IM101, UN Portable, IMDG, ADR/RID, Tanks for the last 15 years and sometimes run into questions on the continued use of older style tanks. Still looking to understand the Jan 1 2010 ruling on the downgrading of im101 hazardous transport tanks. What would you feel is the major difference between an IM101 and Un portable tank?
thanks,
Grant
Referring to IMDG 6.7.3.3.2, do you know what ”minimum MAWP values” means with
regard to non refrigerated liquefied gases?
Hi Russel, I have recently changed my job for survey co. to tank operators, we have lots of modified tanks and I would really help from you. Today is the first time I discovered this site. GREAT SITE!!!
Hi Russel, I must admit with the rest…It’s definitely a great tank-blog. Is there anyway we can link this to our web? We would need a GURU like you in our ISO-tank academy.
Hi Russel,
What is meant by P&G PREPARATION?
Not sure what you mean. Where did you find that phrase?
I mistakenly post sir, what about iso tank cleaning Specification & Procedure?
Hi Russel, do you know max weight can be sustained by bottom outlet valve?
In a pure static condition (no vibration), with a minimum wall thickness in the shear groove (1 mm) on the foot valve, the maximum alowable ‘moment’ is 100 daN m (100 daN at 1meter from the inlet flange). To be safe, if the valve might have already been stressed during its operating time, reduce by 1/2 to get 50 daN m.
I have a Consani 20ft tank container (24k litres) made in 1986. I see Consani have since gone under. Do you know where I might find a general arrangement plan of this container, please?
No sir, I do not. Back in 1986, Consani only had one frame style which was their full-frame design with the large I-beam lower side rails. Most 24000 liter tanks built by them at that time were standard, 4-bar MAWP tanks, insulated with aluminum jacketing, and bottom discharge with 30-degree foot valves.
We have sold a number of those tanks over the years, and could provide a drawing for a small fee if you can send me a picture of the top of the tank (so that we can see the layout/orientation of all the nozzles on top). Please feel free to email me at rharrison@tankservice .com, if you want to discuss further.
Hi, my company is thinking to own few ISO tank for corrosion class 8 product.
What type of the ISO tank we should look for? And is it lead metal lining tank very difficult to find and need to custom made?
Dear Ting,
The exact type of tank container will depend upon the exact product to be shipped. “Class 8 corrosive” is a very broad category. If there is a specific product to be transported, check the SDS sheet for the transport information (usually in Section 14) which will indicate the Proper Shipping Name and UN Number. From there you can determine what specification tank is required. Afterwards you want to consult the SDS again for the physical properties of the chemical (usually in Section 9) to see what the specific gravity of the product is, so that you know how to size the capacity of the tank. Lastly you need to determine what types of linings are suitable, if an interior lining is required. Hopefully you will have alternatives to lead lining, which is indeed a specialty lining and very expensive, not to mention that it will add significantly to the tare weight of the tank and therefore reduce your payload capacity.
