With a 2 layer the r value is between 12 0 and 13 0.
Since this is a sprayed foam product the properties can vary slightly from one tank to the next.
What is the purpose of insulation.
The product is 50 naoh so the idea is to use an electrical heater external to the tank to maintain product temp 80 100f to prevent it from freezing in the winter months.
The polyurethane closed cell insulation on our tanks has an r value between 6 0 and 6 5 per inch of thickness.
We pay special attention to the type of products being stored and utilize the most appropriate and cost effective materials.

The fields in red can be left blank.
The tank construction is cyllindrical 14 id 24 ht carbon steel construction with 0 5 thickness.
If you want to also calculate the freeboard space at the top of the tank so the water level never touches the top then use this optional field remember that 4 inches would be calculated using 3 in.

The tank capacity calculator below allows you to type in your desired tank diameter and height and provides an estimated volume by gallon amount.
Can we say that a minimum storage temperature of 38 oc is adequate for all crudes stored.
Insulation systems can be individually engineered to conform to your specific storage applications.
Is it a floating roof tank as expected or a cone roof tank.
Insulation will delay cooling but will not reduce heat loss to zero.
This is why storage tank insulation is so important for both hot and cold storage as it directly affects the stability of the products inside.
Heat loss from lagged and unlagged sheltered and exposed oil tanks.
