What type of insulation material should be used in LNG vaporization stations?
Thread Content
It seems there are many types? Polyurethane foam, PIR, and also the Folex insulation material that someone recommended recently? Which one is better? Which one offers the best value for money? Thank you to all the sea friends.
The pipes are made of rigid PIR, while the valves and flanges are made of polyurethane foam.
Is Ales a bit expensive? Does it have two levels?
In terms of price, from lowest to highest, they are polyurethane – PIR – flexible insulation materials (the commonly used ones on the market today are German-made Aros and Italian-made K-FLEX). In terms of performance, provided that the quality of installation is maintained, there is not much difference in insulation efficiency among these three types within one year. However, over time, the thermal conductivity of polyurethane and PIR increases significantly, while that of flexible insulation materials remains relatively stable. Both German Aros and Italian K-FLEX claim to be usable for more than 10 years. If you are a contractor, I would recommend polyurethane, as it is the cheapest and does not present many issues during the warranty period. But if you are the property owner, I would suggest using flexible insulation materials such as German Aros or Italian K-FLEX, as they offer better long-term performance with less heat loss, resulting in a higher cost-effectiveness over several years.
