The application of wear-resisting elbow industry: Wear-resisting elbow in addition to used in coal fired power plant

Power, mining, steel, cement, chemical industry, wear-resisting pipe < http://www.naimo.org.cn/ > material conveying, output, is the near distance, high pressure conveying, pipeline under great pressure, and suffered a serious wear, single material pipe is hard to meet the requirements of the working conditions, especially wear-resisting elbow < http://www.naimo.org.cn/ >, for considering its use security, and service life, emphasis on improving pipe lined with toughness and impact resistance, and wear resistance. Also want to consider the overall strength of the piping and elbow problems. Wear-resisting elbow (UHMWPE) by the national ministry of science and technology achievements in science and technology, classified as a national key promotion plan, is a chemical new materials and new products. This kind of product manufacturing the elbow has anti-aging, long service life, wear resistance, impact resistance, corrosion resistance, self-lubrication, resistance to bond, easy for construction, and many other advantages, solve the PCCP pipe, steel, cast iron, glass tube leakage serious, high cost, construction difficulty, long construction period series problem.

Ultra high molecular weight polyethylene (uhmw-pe) is higher than 1.5 million molecular weight linear polyethylene, as a new engineering plastic, collect a variety of excellent performance in one:1 and wear resistance of the champions league in the plastic than nylon 66 and ptfe high 4 times, more than six times as high carbon steel;2, impact strength is the head of the listed plastic, for PC 2 times, ABC 5 times, and can in liquid nitrogen temperature (196 °C) maintain high toughness;3, self-lubricity and ptfe quite, friction coefficient of just 0.07-0.11;4, impact can absorb in the value of all plastic for high, quieter effect;5, the chemical stability is very high, in a certain temperature and the concentration range ability all kinds of corrosive medium and organic medium role;6, fight adhesion ability is extremely strong, second only to ptfe;7, completely health non-toxic, can be used to contact with the food and drug;8, density in all the least engineering plastic, than ptfe light 56%.

In order to display of ultra-high molecular weight polyethylene high wear resistance, excellent performance, improve the processing properties, make its products in mining, power, petrochemical, metallurgical and other industries to get better use, my company and many authoritative research institutions and technical cooperation, and made great technological breakthrough, several technological achievements in international advanced level. I company produces the pipes, plank, pipe fittings (elbow, the three links), profiled products, chemical building material test by national testing center, achieve the targets standard requirements. In 2001, our products were the United States environmental technology export committee confirmed as the green environmental protection technology (products), and China's industrial high-tech BBS organizing committee confirmed for 2001 China the high-tech industrialization of achievement projects. In 2002, our company ultra high molecular weight polyethylene pipe the state economic and trade commission recognized for 2002 annual national key new product.
