Pipes can convey various kinds of energy materials (water, gas, oil, etc.) in daily life and industrial production. It occupies an important position in national economy. People understand the inconvenience brought by the pomp of pipe, corrosion of pipe and second time pollution in daily life and industrial production.         Now the galvanizing steel pipe, cast iron pipe, concrete pipe, plastic pipe and stainless steel pipe we used have many problems in different degree, these problems include easy to be corroded, polluted, low strength, high cost, heavy or short life, etc. For example, when galvanizing steel pipe and steel pipe are buried under ground, it will be corroded easily; when the plastic pipe be heated, its pressure bearing ability will be low; the cast iron pipe is high cost and heavy.         How to make the pipe has the perfect properties of nonpoisonous, corrosion-resisting, heat-resisting, anti-lashing at the same time is a difficulty in the world. The new type composite pipe, glass fibre reinforced plastic pipe was researched and developed by advanced countries in Europe and America. It brings a revolution of pipe materials to China, and these pipes are called " Green Pipe". State Ministry of Construction and domestic provincial government has attached great importance to this, and this was chosen as Scientific Results Promoting Project of Ministry of Construction, and it has already been applied to the building industry in many cities in China.    HQ Add：High Technology industrial zone MiQuan XinJiang P.R.C. 831400 Tel：86-994-5216825 86-994-5318888 Fax：86-994-5318666 ICQ:329284564
