Structure:
Work within steel tube, antiskid layer drag reduction, inorganic, organic thermal insulation layer, outer insulating layer, reflection protection of steel pipe, anti-corrosion layer
Scope of application: medium temperature < 350 ℃
Main advantages:
Apply to high temperature, heat preservation performance is good, bearing resistance, long service life, direct buried, do not take up space, is advantageous to the urban construction planning.
Main material:
Anti-skid layer drag reduction - as CiXing fiber material heat resistance in red above, commonly used aluminum silicate fiber felt.
Inorganic heat insulation layer - commonly used double microporous calcium silicate segment or magnesium silicate segment (also used glass wool)
Reflector, with strengthen aluminum foil, coefficient of thermal conductivity < 0.05 W/mK, and heat-resistant < 300 ℃, the shoot rate of > 90%
In the organic insulation paint, epoxy coal asphalt + alkali glass fiber cloth.
In strengthening, primer, paint, alkali glass fiber glass cloth, paint (dry film thickness > 0.4 mm)
Strengthen level: the bottom paint, paint, alkali glass fiber cloth, paint, alkali glass fiber cloth, paint, paint dry film thickness > 0.6 (mm)
