硅酸铝保温材料，耐火材料，高温玻璃棉-九天耐火保温材料有限公司

   Directly buried insulating pipe is a steel pipe, polyurethane rigid foam insulation layer and the glass before who reinforced plastics (FRP) combined closely with the outer sheath of prefabricated pipe.  

Directly buried insulating pipe has the capacity of lightweight, high strength, thermal insulation, sound insulation, flame retardant, cold resistant, anti-corrosion, water absorption, excellent features such as convenient construction, has become the building, transportation, petroleum, chemical, electric power, refrigeration industry, such as heat insulation, waterproof plugging, door seal, etc. The indispensable materials. For all kinds of indoor and outdoor pipeline directly buried insulating pipe, central heating, cooling, steam, oil, transport, etc all kinds of pipe, central air conditioning pipe, chemical, pharmaceutical and other industrial pipe insulation, cold insulation engineering. 

Directly buried insulating pipe than traditional kinds of bao wen pipe has the very outstanding advantages: 

1, insulation performance is good, the heat loss is only 25% of the traditional pipe material, shipping line can save a lot of energy for a long time, significantly reduce energy costs.  

2, has a strong waterproof and anti-corrosion ability, don't need to attached pipeline, directly buried under the ground or water, is simple rapid construction, low comprehensive cost. 

3, under the condition of low temperature and has good corrosion resistance and impact resistance, can be directly buried permafrost. 

4, the use life of life can be up to 30 to 50 years, correct installation and use can make the network maintenance costs low.
