Note:
1. The above specifications are common specifications. If you need special specifications, you can make them according to your requirements.
2. The sheets and pipes are black. If you need special colors, we can make them according to your requirements.
3. It is recommended to use plates when the pipe outer diameter exceeds 89mm.
4. The thickness of thermal insulation material needs to be more than 25mm, and it should be packed in multiple layers until the required thickness.
No need for built-in expansion joints
WOBO flexible ultra-low temperature insulation system does not need to use fiber materials as fillers for expansion and contraction. On the contrary, it is only necessary to install each layer of low temperature elastomer materials with pressure ,according to the recommended reserved length to solve the expansion joint problem required by the traditional system.
Temperature range -200ºC to +125ºC
The most economical and reliable cold insulation system, multi-layer composite structure, overcomes the stress at low temperature and provides maximum mechanical properties. It has low thermal conductivity and good insulation effect under the condition of low temperature and deep cooling, and the oxygen index is as high as 32 or more. Used for cold insulation with temperature as low as -200ºC.
It can still keep elasticity at ultra-low temperature.
WOBO ultra-low temperature cold insulation products have the characteristics of low thermal conductivity, light weight and elasticity at low temperature. The unique color of this product is easy to identify and install. In some occasions, it can be constructed with cold without stopping, greatly reducing joints to ensure the air tightness of the system and improve the construction speed. There is no fiber and dust.
No need of built-in moisture-proof and steam-proof layer
WOBO low temperature insulation system does not need to install moisture barrier. Thanks to the unique closed-cell structure and polymer mixed formula, NBR elastic foam material has a high water vapor permeability resistance. This foaming material can make the product have continuous water vapor permeation resistance in the whole thickness direction.
Other Advantages and features
* Excellent thermal insulation performance-very low thermal conductivity.
* Seismic resistance-the ability to absorb pipeline vibration and external impact.
* Lower temperature variability than traditional rigid insulation.
* More durable and low maintenance rate.
* Non-corrosive and durable.
* Good deformation resistance.
* ASTM/SGS/BS476/UL/GB certification.
Diolefins, Nitrile rubber Ultra-low Temperature Insulation System is a high-performance diene elastic foam specially developed by WOBO for thermal insulation engineering under ultra-low temperature conditions. Our company's ultra-low temperature insulation system has the inherent characteristics of shock resistance, and its low temperature elastomer material can absorb he energy of external mechanical impact and vibration to protect the system structure. The impact force from any part can be widely dispersed and attenuated by the elastomer material, so as to avoid the cracking risk caused by stress concentration like the rigid foam insulation material. Reducing temperature stress is one of the important features of this cold insulation system,which is superior to traditional rigid foam insulation materials such as foam glass, polyurethane PIR and PUR. These traditional hard materials have no elasticity at normal temperature and low temperature, so there is a general phenomenon that the thermal insulation structure is damaged under external force and the thermal insulation performance is reduced due to extrusion cracking of the materials under temperature-varying stress.
The flexible ultra-low temperature insulation material is a closed-cell elastomer insulation material, which has excellent properties such as softness, cold resistance, heat resistance, flame retardance, water resistance, low thermal conductivity, shock absorption and sound absorption. It can be widely used in various cold and hot medium pipelines and containers in industries and departments such as construction, chemical industry, medicine, metallurgy, ships, vehicles, etc., and can achieve the effect of reducing cold loss and heat loss. Because of its convenient construction, neat and beautiful appearance, and no pollution, it is a high-quality cross-century new generation thermal insulation material.
WOBO is a professional manufacturer of R&D, design, production and manufacture of rubber and plastic products in China. The rubber and plastic products produced by the company have better thermal insulation and incombustibility than traditional thermal insulation materials, and also have better energy saving.
