Tianjin high-density polyethylene outer sheath tube supply _ Tianjin high-density polyethylene outer sheath tube New Supply Sales Hotline: 13653268310 Guo Jingli Advantages prefabricated buried pipe insulation prefabricated buried pipe insulation than traditional pipe insulation has a very prominent way Advantages: 1, prefabricated buried pipe insulation does not require masonry massive trench, simply pipe insulation were buried underground, thus greatly reducing the engineering area, are environmentally friendly, reducing the earth excavation is about 50%, reduce civil masonry and concrete amount of 90%. Meanwhile, the insulation construction and site trenching parallel, just live joints, can shorten the duration of about 50%. 2, good insulation properties, heat loss is only 25% of the traditional pipe, long run can save a lot of energy, significantly reduce energy costs. 3, has a strong waterproof and corrosion resistance, without attached trench can be directly buried in the ground or water, construction easily and quickly, and lower total cost. 4, at low temperatures also have good corrosion resistance and impact resistance, and can be directly buried underground permafrost. 5, the service life of up to 30 - 50 years, proper installation and use can make the pipe network maintenance costs low. 6, can set the alarm system, automatic detection of pipeline leakage fault, an accurate indication of the fault location and automatic alarm. New insulation materials recently, the experts redefines green materials --- take in raw, product manufacture, use or recycling, and waste treatment and other aspects of the Earth's environmental impact is minimized and benefits to human health materials, also known as " Environmental Harmony Materials. " Using good insulation techniques and materials in the construction and industry, can often play a multiplier effect. Statistics show that buildings use one ton each mineral wool insulation products, a year can save one ton of oil. Beijing Court North saving residential use case shows that the rate of coal per year per unit area 11.91 kg of standard coal / square meter. Industrial equipment and piping insulation, using good insulation measures and material, can significantly reduce energy consumption and costs, improve the environment, while better economic benefits. Such as: industrial equipment and pipeline projects, good insulation conditions, heat loss can be reduced by about 95%, usually for about a year investment in insulation materials can save energy recovery. Prior to 1980, the development of thermal insulation material is very slow, the few insulation materials plant can only produce a small amount of expanded perlite, expanded vermiculite, slag wool, fine glass wool, porous calcium silicate products, mineral wool Few plant, the production capacity is insufficient tons, loose cotton, calcium silicate insulation material and only three, annual output of 8,000 cubic meters. The number of products, the quality can not meet the requirements. The main energy-saving insulation material situation contrasts as follows: mineral wool and mineral wool products is a high quality insulation materials, more than 100 years of history of production and application. Britain was first discovered in 1840 after the formation of the fibers melted slag blow, and production of slag wool; in 1880, Germany and Britain began producing slag wool, only after other countries have been used and produced, beginning in the 1930s large-scale production and use; from 1960 to 1980, the world's most rapidly mineral wool; after 1980 so far, the international production of mineral wool products in a relatively stable stage, mainly because other insulation materials such as glass wool, foam accelerated development, combined with the developed countries slow down the pace of development in recent years around the world mineral wool products output of about 800 million tons of mineral wool the most widely used in construction, such as the UK accounted for 85%, Germany 70%, Japan accounted for 92 percent, the United States accounted for more than 90%. Beijing to introduce our early 80s Sweden 16,300 tons production line of insulating material more superior to the scale, performance, different specifications more complete direction a big step forward. Subsequently, Harbin, Taiyuan, Hohhot, Qiqihar, Urumqi, Dongguan, Yinchuan, Xining, Shanghai, Beijing one after another from Sweden, Japan, Australia, Italy, Britain, Poland introduced, China has built a production line in Nanjing. Production capacity of 3,000 tons / year had 80, the company has about 180 design capacity of 550,000 tons. Rock wool production technology: the degree of uniformity of small factories producing wool difference; the introduction of equipment Bumian automatically adjust the speed and thickness, the cotton more active wheel speed quickly, there is a proportional relationship, therefore, manufacturers of wool uniform density, low shot content. Glass wool and rock wool products following the emergence of a light weight, good thermal insulation properties of thermal insulation materials. Japan 90 annual output 205,000 tons, the annual output of 1.925 million tons the United States 1985, France 1984 annual output of 115,000 tons. 80 years ago, only a few of superfine wool small factories, a single species, poor quality, 80 metaphase, Shanghai, Beijing Dong Fang introduce technology and equipment, the use of centrifugal blowing production, products include: plates, carpets, shells, decorative ceilings. Features: light weight, general 10-96kg / m3,20kg / m3 or less for the carpet, 24-48kg / m3 as the hard plate, 48-96kg / m3 for the hard plate, wherein 48kg / m3 can be ceiling, a softening point of 500 Fei around, holding 300 Fei, the United States a larger amount, k = 0.9. Calcium silicate insulation products, the successful development of the country 70 years, with high compressive strength, thermal conductivity, easy construction, can be used repeatedly characteristics, is widely used in the power system.
