With three vacancies abroad Qingdao Plastic Machinery Co. JDPE double wall corrugated pipe production equipment filled, is pipe series forward in a new field. Market potential analysis drainage is indispensable modernization of municipal infrastructure construction, compared with developed countries, China's municipal drainage level is very backward, our country is facing a historic opportunity to invest heavily in the construction of drainage network. China is a serious shortage of water resources in the national double-wall corrugated pipe production line, less than 2400 cubic meters of water per capita, for a quarter of the world's per capita water. In many cities and regions in China can ensure the water supply of residents has become the primary problem facing the country less than 668 cities in more than 400 water supply. Important cause of the water crisis is to be no control of water, drainage untreated contaminated, for example, China's seven major rivers flowing through the river in 15 major cities, there are 13 river water pollution. Water pollution is also directly harm to all aspects of economic life and health of the people. Now large-diameter double-wall corrugated pipe production line, the whole country are calling for the protection of water resources, water pollution. In such a situation, the drainage project has become a hot topic around the infrastructure, the drainage pipe network engineering platoon is part of its core. Therefore, we predict that in the next two years, China will enter the construction of drainage network of climax, for plastic pipes buried created unprecedented opportunities for development. Plastic Machinery Co., Ltd. Qingdao with three production of various models of various materials double-wall corrugated pipe equipment, superior performance. Direct extrusion of double-wall corrugated pipe production line is divided into two kinds of PE and PVC, PVC double wall corrugated pipe production line, which due to the material properties of PVC, pipe diameter and height of the peaks is limited. Production capacity can not meet the needs of the Chinese market, and imported equipment is expensive, so ROI is greatly reduced. The last two, three years, double-wall corrugated plastic pipe production line, some powerful presses domestic enterprises have begun research and development of large-diameter double-wall corrugated pipe production line. These enterprises in Qingdao in learning and absorbing foreign advanced production equipment on the basis of double-wall corrugated pipe production line, through technical research, comparative advantages and disadvantages of various foreign equipment, the use of complementary advantages, the successful launch of the international advanced level caliber double-wall corrugated pipe production line . Plastic Machinery Co., Ltd. Qingdao with three market has successfully launched more than a dozen production lines, has been widely recognized by the market. Currently, up to 1200mm diameter double-wall corrugated pipe production line is being developed. If the success of this technology will facilitate greater domestic double wall corrugated pipe applications. Currently in the world that can really produce more than 800mm double-wall corrugated pipe production line manufacturers, but also two, three spiral double-wall corrugated pipe production line _ _ double-wall corrugated pipe production line with three presses offered by Qingdao with three Plastic Machinery Co. . Plastic Machinery Co., Ltd. Qingdao with three (www.tongsansuji.com) strong, credible, Qingdao, Shandong Province in other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead you to join with three presses and into the brilliant, for a better future!
