The Insulation Thickness Table sheet defines all possible sizes, temperature ranges, and insulation thicknesses available for the insulation specifications. Before defining ranges and insulation thicknesses on this sheet, you must list the insulation specifications on the Insulation Spec sheet.
Spec Name
Type the insulation specification for which you want to define thickness ranges.
NPD Low
Specify the smallest pipe diameter to be considered in this range.
NPD High
Specify the largest pipe diameter to be considered in this range.
NPD Unit Type
Specify the units of measure for the NPD Low and NPD High columns. Each delivered insulation specification is defined in both imperial and metric units.
Temperature Low
Specify the lowest temperature to be considered in this range. Include the temperature unit of measure (K for Kelvin, F for Fahrenheit, or C for Celsius) when specifying this value.
Temperature High
Specify the highest temperature to be considered in this range. Include the temperature unit of measure (K for Kelvin, F for Fahrenheit, or C for Celsius) when specifying this value.
The temperature from the 3D model must be greater than the lower bound and less than or equal to the upper bound. The exception is the lowest range in each section on this sheet, where the temperature can be greater than or equal to the lower bound and less than or equal to the upper bound.
For example, the lowest range for insulation made of calcium silicate is 100F – 400F. Therefore, you can type 100F. Note the = sign between Temp_lo and t in the following expression.
Temp_lo <= t <= Temp_hi
For the other ranges, such as 401F – 500F in the calcium silicate section, you can only specify a number between and including 402F – 500 F. Note there is no = sign between Temp_lo and t in the following expression.
Temp_lo < t <= Temp_hi
Thickness
Specify the thickness of the insulation. Include the unit of measure when specifying this value.
