Mining Polyethylene Composite Pipe
Cross helically wound steel wires reinforced-polyethylene composite pipe (SRCP) is a kind of composite metal plastic pipe with excellent overall performance. With excellent pressure bearing performance, good flexibility, long-term resistance to acid and alkaline corrosion and abrasion, it is suitable for long-distance underground pipes for water supply and drainage, slurry transportation and the like, especially for subsidence region such as mining area, river channel.

According to reports, the developed countries support the development of national industries and there are a series of supporting policies and regulations. For example, in the course of developing nuclear power in France, the proportion of compulsory introduction of core technologies was no more than 25%. In order to revitalize the domestic equipment manufacturing industry, Japan has promulgated the "Provisional Measures for the Promotion of Machinery Industry". Drawing on foreign practices, during the “11th Five-Year Plan†period, China will also successively promulgate and implement a series of policies, laws and regulations, and standardization measures to revitalize the equipment manufacturing industry in line with its own national conditions. Some of these policies and measures are still in the brewing stage, and some have already been enacted and have achieved ideal results. For instance, the major technical equipment insurance mechanism has been tested in the localization project of Hualu Hengsheng Large Chemical Fertilizer Co., Ltd.; the joint reorganization between equipment manufacturing enterprises has also made encouraging progress.
It is understood that the output value of equipment manufacturing industry in 2005 accounted for 12.73% of China's GDP, and it has become a veritable pillar of the national economy, making a huge contribution to domestic taxation and employment. At the same time, equipment manufacturing industry is still an industry with great influence, low competitiveness, and high external dependence. Since the 1990s, the demand for localization has become smaller and smaller, and it has been argued that localization goes against the spirit of reform and opening up and the principle of market economy. Affected by this, the current domestic equipment manufacturing industry is faced with many problems: the first set of equipment to enter the market is difficult, the performance threshold is high; repeated introduction of many, such as large-scale fertilizer plant repeatedly imported 34 sets, resulting in the domestic equipment manufacturing industry can not keep up Steps; tax system upside down, providing a large number of convenient conditions for imports; price advantage is gradually losing; equipment manufacturing industry is thin, lack of independent development investment, technology reserves are not enough; the industry down the price of each other, vicious competition prevails. However, the high speed of economic development cannot be maintained forever, but in the end it will enter a period of flattening. The current surface prosperity of the equipment manufacturing industry is unsustainable. Therefore, the promulgation of policies and measures to revitalize the equipment manufacturing industry will bring about a gospel for the sustainable development of China's equipment manufacturing industry.
The reporter recently learned from the National Technology Reform Coordination Office of the National Development and Reform Commission that for the current situation in China's equipment manufacturing industry, “the core technology manufacturing companies are not able to, independent product users and enterprises are not used, and the key link control system is weakâ€, the State Council and relevant ministries and commissions have successively introduced or Research and drafting of a series of policies and measures to revitalize the equipment manufacturing industry are under way.
