Armstrong Rubber and Plastic foam insulation materials for cryogenic insulation materials key to the prevention of low temperature (-40 ~ 0 ℃) under the contract, especially when multi-layer insulation close to the most inner tube refrigerant contraction usually selected freshman specifications diameter pipe insulation to prevent contraction.
Of liquid nitrogen and other cryogenic medium (-40 ℃ under) the heat, after the first layer of insulation material, shall be at least 0.05mm thick paste completely cover the aluminum foil as an additional layer of steam traps, and the second layer and the remaining layers joints, interfaces should be covered with sheet overlapping paste. Shen remember Armstrong Rubber and Plastic foam insulation materials in addition to systolic diameter, the thickness direction will shrink, so the total thickness of insulation layer to sufficient safety margin. Usually conditions (ambient temperature 20 ℃, relative humidity 70%), the use of Armstrong rubber foam insulation sheet, the total insulation thickness of about 150mm.
Under low temperature Armstrong Rubber and Plastic foam insulation materials will lose elasticity and hardening, embrittlement but does not affect performance.
Under low-temperature thermal insulation thickness of the selection please contact our technical department. |
