PIR pipe shell is a kind of thermal insulation material, which is used in various pipelines such as heat supply, refrigeration, oil and steam transmission.



The thermal conductivity of RIGID polyurethane insulation pipe shell is the lowest among insulation materials, so the heat loss of materials can be reduced to the minimum.
