In the selection of cold pipe insulation materials, no material can be called “the best”, because the choice depends on the specific application scenario, cost budget, insulation effect requirements and construction conditions and other factors. However, based on the information in the reference article, here are some common cold pipe insulation materials and their characteristics for your reference:
Rock wool board
Thermal conductivity: 0.041-0.045
Features: fireproof, flame retardant, high temperature absorption, but relatively poor thermal insulation effect.
Glass wool
The construction is simple and can be cut at will
Antibacterial and mildew-proof, anti-aging, anti-corrosion
Low moisture absorption and stable physical properties
Expanded polystyrene board (EPS board):
Thermal conductivity: 0.037-0.041
Features: Good thermal insulation effect, cheap price, but slightly worse strength.
Extruded polystyrene board (XPS board):
Thermal conductivity: 0.028-0.03
Features: better thermal insulation effect, high strength, moisture resistance, but the price is more expensive, and the surface needs to be treated during construction.
Polyurethane foam material:
Thermal conductivity: 0.025-0.028
Features: good waterproofness, good thermal insulation effect, high strength, strong integrity, but poor fire performance, the price is more expensive.
Rigid polyurethane sheet
Thermal conductivity: 0.018-0.023
Features: low thermal conductivity, good thermal performance, is the lowest thermal conductivity among all insulation materials.
Rubber and plastic pipe insulation material
The thermal conductivity is low, the independent bubble structure is fine, there is no air convection, the closed-cell structure is complete, and the thermal insulation effect is good
It does not absorb water, does not condensate, and has a long service life
The appearance is soft and beautiful, easy to bend, and the construction is convenient and fast
Polyethylene insulation
Odorless, non-toxic, non-absorbent, moisture-proof, pest-proof
Excellent tensile strength and thermal insulation properties, good weather resistance and corrosion resistance
Composite silicate insulation material
Low thermal conductivity and high temperature resistance
Easy construction, no irritation, no dust pollution
When choosing cold pipe insulation materials, the following factors should be comprehensively considered:
Thermal insulation effect: The thermal conductivity of the material is an important index to evaluate the thermal insulation effect, the lower the thermal conductivity, the better the thermal insulation effect.
Cost: The cost of different materials varies greatly, and should be reasonably selected according to the budget.
Construction conditions: consider factors such as the difficulty of construction of materials, the requirements for construction personnel, and the construction period.
Use environment: Consider the use environment of the pipeline, such as temperature, humidity, corrosiveness and other factors, and select suitable materials.
To sum up, for the selection of cold pipe insulation materials, comprehensive consideration should be carried out according to specific needs and conditions, and the most suitable materials should be selected.
