There are many types and options for cryogenic pipe insulation, each with its own unique advantages and disadvantages. Here are some common cryogenic pipe insulation materials and their advantages and disadvantages:
Rubber and plastic spongeAdvantages
soft, flex resistance, cold resistance, heat resistance, flame retardant, waterproof, low thermal conductivity, shock absorption, sound absorption and other excellent performance. It is suitable for the insulation engineering of various pipes and equipment, especially for low temperature environment.
Disadvantages: The price is relatively high, and it is necessary to pay attention to the sealing during construction to avoid the decline of thermal insulation performance caused by the entry of water vapor.
Rock wool pipe:
Advantages: medium thermal insulation performance, non-combustion, relatively low price. It is widely used in the insulation of partition walls and pipes in the construction industry.
Disadvantages: The water absorption rate is high, and the fiber has a certain irritation to the human body. When used in a humid environment, it is necessary to pay attention to its moisture absorption performance.
Glass wool insulation
Advantages: high thermal insulation performance, non-combustion, moderate price. Good formability, low density, low thermal conductivity and strong corrosion resistance.
Disadvantages: It also has a high water absorption rate, and the fiber has a certain irritation to the human body.
Polyurethane insulation
Advantages: good thermal insulation performance, low water absorption, high hardness, long life. It is widely used in cold storage, refrigerated trucks and other low-temperature environments.
Disadvantages: flammable, and relatively expensive.
Composite silicate insulation material
Advantages: low thermal conductivity, good thermal insulation performance, convenient construction, no irritation and pollution to the human body.
Disadvantages: Low tensile strength and may not be suitable for all types of pipe insulation needs.
When choosing low-temperature pipeline insulation materials, it is necessary to comprehensively consider the thermal insulation performance, price, construction convenience, safety and environmental factors of the materials. At the same time, proper construction and maintenance are key factors in ensuring long-lasting insulation. Therefore, when choosing insulation materials, it is recommended to consult professional engineers or insulation material suppliers for more accurate advice and guidance.
