Selection of insulation and cooling materials for pipelines
Thread Content
What type of insulation material is generally used for pipeline insulation? What type of insulation material is generally used for pipeline insulation? Can heat retention and heat insulation be applied interchangeably in terms of insulating materials? I would like to ask whether it is possible to use the same type of insulation material for a steam pipe with a diameter of DN100 at 200 degrees Celsius and a liquefied gas pipe with a diameter of DN100 at -20 degrees Celsius. Please give me your advice. Thank you!
For insulation, rock wool is commonly used, while polyurethane materials are more often used for heat retention; you can check specific models online
Reply to 4# Su Yan Effect: Are there also several types of rock wool materials?
Rock wool is the most common insulating asbestos. For higher-end applications, aluminum silicate asbestos boards or calcium silicate asbestos boards can be used. In addition to foam boards, expanded polyurethane is also used for insulation.
Rock wool is generally used for insulation, while foam polyurethane is used for cold insulation
Are there any guidelines? Or anything else? I’d like to take a look
For temperature insulation, aluminum silicate insulation foam should be used, while foam polyurethane is used for heat retention
