company introduces

       In 1999, company decision-makers adjust product structure and realize new ideas, two industries develop together, stabilize old product farm equipment and develop new building materials product to promote the enterprise lasting development in the 21st centry. Depending on our own 50 million yuan investment, we developed Aluminum-plastic composite pipe, PP-C pipe, PP-R pipe, PEX pipe and supporting pipe, thereinto, 6 pipe production lines with 20 million meters capacity annually, 80 sets of pipe equipments with 20 million pipe fittings capacity annually. In October, 2000, Shuangxing Pipe fittings got the International Quality System Certificate of ISO9002.
　　 It’s a revolution for soft plastic pipes such as new type Aluminum-plastic composite pipe, PEX taken as key promotion by State Construction Ministry for it always represented by galvanized steel. Since the beginning of the 90s, new type steel including Aluminum-plastic composite pipe, PEX pipe those soft plastic pipe are popularly at that time. Long time of non-solving the issue of pipe leakage, sealed resistance of diameter, water quality secondary pollution caused by copper inlay pieces and pipe surface rust in the connection of heat supplyment blocks the promotion and application of new type pipe severely.
　　 In order to solve the world puzzle, Shuangxing Group invest 10 million yuan to organize a research team composed of talents in May, 2000, to focus on the development of new type pipe. After more than one year research, Shuangxing Modified Polycarbonate Pipe Fittings, a new generation green environmental protection pipe fittings acquired 8 state patents leading and filling the blank in domestic, successfully got appraisement of science and technology achievement from Construction Ministry on June, 30th, 2001. The invention of the product succeeded in solving those three puzzles, leakage, resistance of diameter and rust restricted by pipe sealing technology in the connection of Aluminum-plastic composite pipe, PEX pipe and other soft plastic pipes. In addition, it provides reliable guarantee for the promotion and development of new type green environment pipe.
    The successful development of Shuangxing pipe is lucky to our pipe industry and brings the evangel to our customers. Shuangxing pipe won the reputation of “The Hope of Rising China Aluminum-plastic Pipe Development” from industry experts.

The successful development of Shuangxing pipe arouses great concern of many medias including China Construction Newspaper, China Building Materials Newspaper, China Architecture Newspaper and Shandong Construction Newspaper, which reported special reports of the development of Shuangxing modified polycarbonate pipe with big headings and receives tremendous feedback in customers and similar industries.
The successful development of Shuangxing pipe attracts a large number of real estate developers. Many state key projects such as Jinan Yajuyuan Residential Area, Jinan Shunhu Xinqu Residential Area, Wuhan Tap Water Corporation and Beijing Huilongguan Residential Area vie with each other to choose Shuangxing pipe fittings.
    Tested by State Chemical Building Materials Testing Center, Shuangxing modified polycarbonate pipe fittings first adopts thermal plastic pipe and pipe fittings used in cold water and hot water with international standard ISO10508, carries out the adaptability test in pipe system in domestic. In addition, it’s an ideal pipe fitting first passes tests of thermal cycling and high-low temperature between 23℃ and 95℃ test for 5000 times in domestic. PP-R, PP-B pipe and fittings have past through the thermal cycling test of State Chemical Building Materials Testing Center (1.0Mpa, alternate once between 20℃ and 95℃ lasting for 5000 cycles) without leakage and damage. No leakage and damage under 110℃ central stress, 1.9Mpa, 8760h in the thermal stability test. It is popularly in our wide customers for its huge application value in development foreground and promotion after the product launch.
