Floating body material patent

From 20 13, in the era of environmental protection as the theme, the new multifunctional plastic pipeline industry is also working towards this goal, which is characterized by corrosion resistance, aging resistance and environmental protection. Environmental protection and safety are becoming more and more popular, especially in mine dredging industry. New plastic pipes can not only replace steel pipes in large quantities, but also save energy, materials and sanitation. State, improve the living environment, improve the function and quality of the building, reduce the weight of the building, make? The advantages of convenient operation make the application field of plastic pipe widen day by day. Besides architecture, cities? Government water supply and agricultural (water supply, irrigation and drainage) pipelines continue to grow, while municipal sewage, communication and electricity? The proportion of electric power, gas, heating, medical treatment, sand pumping pipeline, dredging and mining industries is also increasing. ? From 20 10, the amount of ultra-high molecular weight polyethylene (UHMWPE) and other materials increased rapidly; There are more than 1500 utility models and invention patents for plastic pipes in China; It has reached a certain international advanced level in ultra-high molecular weight polyethylene (UHMWPE) pipes, plastic and metal composite pipes.

With the acceleration of technological progress, new technologies, new materials and new processes are constantly emerging? Compared with traditional materials, the advantages of plastic pipes are more and more prominent. Compared with the traditional metal steel pipe, the new wear-resistant plastic ultra-high molecular weight polyethylene (UHMWPE) pipe has the advantages of light weight (generally only 1/8 of steel pipe), corrosion resistance, impact resistance, good tensile strength, low-temperature frost cracking resistance and no scaling, and the inner surface of UHMWPE pipe is smoother than that of cast iron pipe. Large sliding amount, low friction coefficient and small fluid resistance can reduce the energy consumption of medium transportation by more than 9%. Comprehensive energy saving is good. ? Convenient transportation, simple installation and long service life up to 30-50 years. Polyethylene pipe has developed rapidly all over the world, and developed countries have applied it to mining, dredging, coal chemical industry, electric power, marine lakes and other fields. The new wear-resistant plastic ultra-high molecular weight polyethylene (UHMWPE) pipe has gained the upper hand. Ultra-high molecular weight polyethylene (UHMWPE) pipe is a new type of wear-resistant plastic. Due to the continuous innovation of new plastic pipe technology in recent years, it is widely used not only to replace steel pipes and cast iron pipes, but also to replace cement pipes. In 20 13 years, the national output of plastic pipes120,000 tons, and the consumption of raw materials for PP pipes is about 550,000 tons, among which the consumption of raw materials for UHMWPE pipes is 240,000 tons.

Some far-sighted manufacturers have turned their attention to dredging, mining and municipal engineering, and introduced advanced pipe processing production lines, so that China has more than 90 such pipe processing production lines, of which Luoyang Guorun Pipe Industry Co., Ltd. has 30 production lines with an annual processing capacity of 300,000 tons. At the same time, some end users are familiar with the advantages of the new wear-resistant plastic ultra-high molecular weight polyethylene (UHMWPE) pipe, and choose UHMWPE pipe to replace the traditional steel pipe and cast iron pipe, which greatly saves manpower and material resources, obviously improves the transportation effect, and greatly shortens the period of pipeline maintenance and replacement. ?
