Let’s look at an example of how to calculate insulation thickness for steam pipe lagging.<\/p>\n
We will calculate the stone wool insulation thickness for a 6-inch steam pipe at 200\u00baC temperature, 150 meters long. We will set the TYPE OF CALCULATION section as follows:<\/p>\n<\/div>

Next is the INSULATION REQUIREMENT section, which is very important for determining stone wool insulation thickness.<\/p>\n
Personal Protection<\/h5>\n
This value is used to protect people from contact, consisting of 3 parts:<\/p>\n
\n- Ambient Temperature is the environmental temperature around the steam pipe in areas where people can make contact, such as factory temperature<\/li>\n
- Wind Speed is the wind velocity in areas where people can make contact. For locations without wind, enter 0<\/li>\n
- Max surface Temperature is the maximum temperature at the insulation jacket surface, typically set at 55 \u00baC<\/li>\n<\/ol>\n
HEAT LOSS \/ COOLING \/ ENERGY SAVING<\/h5>\n
Calculating stone wool insulation thickness to reduce thermal energy loss<\/p>\n
\n- Ambient Temperature is the environmental temperature around the steam pipe for calculating heat loss<\/li>\n
- Wind Speed is the wind velocity for calculating heat loss<\/li>\n
- Max heat loss per length is the maximum thermal energy loss per meter<\/li>\n
- Max heat loss per area is the maximum thermal energy loss per area<\/li>\n<\/ol>\n<\/div>
