Ca corrosion allowance.
Storage tank insulation calculation.
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.
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.
Sd allowable stress for design condition.
What is the purpose of insulation.
With a 2 layer the r value is between 12 0 and 13 0.
The polyurethane closed cell insulation on our tanks has an r value between 6 0 and 6 5 per inch of thickness.
E joint efficiency.
The fields in red can be left blank.
Temperature limits for some commonly used insulation materials.
Since this is a sprayed foam product the properties can vary slightly from one tank to the next.
Watts loss from insulated surface.

D normal tank diameter in feet.
H depth of tank in feet.
Oil tanks heat loss.
The tank capacity calculator below allows you to type in your desired tank diameter and height and provides an estimated volume by gallon amount.
A foam system for storage tanks is an excellent way to preserve the integrity of the product and ensure the best insulation for the tank.
Above k factor information used to calculate heat losses comes from letco incorporated catalog.
We pay special attention to the type of products being stored and utilize the most appropriate and cost effective materials.
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.
Td td tt 2 6 d h 1 st td miniumum shell thickness in inches.
The tank construction is cyllindrical 14 id 24 ht carbon steel construction with 0 5 thickness.
The insulation is calcium silicate with a 2 5 thickness.
Required heat for maintaining above tank.
Calculation form to determine watts required to replace heat losses from an insulated surface complete the fields below.
5 oc to 55 oc is the range between max and min ambient temperatures ever.
G design specific gravity of liquid.
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.
Can we say that a minimum storage temperature of 38 oc is adequate for all crudes stored.
