Chongqing PipelineIt is the biological base pipe of the earlier industrialization in the world. They are also the original conduit of China. It has significant advantages in pressure, deformation resistance, thermal insulation performance, service life and comprehensive cost. At present, bamboo winding composites industry is still in the early stage of development, it is urgent to put in place relevant guidance and policy support. The National Development and Reform Commission has developed and promulgated guidelines and development plans for bamboo winding composites and their industrialization. Second, the Ministry of Finance promulgated the bamboo winding composites industry manufacturing equipment and product market application subsidy policy, industrialization financial support policy, raw material forest base construction fund subsidy policy. Third, the Ministry of Commerce will bamboo winding composite materials industry into the "South-South cooperation", the national Development and Reform Commission will be bamboo winding composite materials industry projects into the "Belt and Road" promotion Project library.
Chongqing pipeline is a mature product of bamboo composites. Compared with traditional pipelines, the advantages of energy saving and emission reduction are obvious. The energy consumption per unit length of the pipeline during the entire production process (pipe diameter is 1000 mm). By 2020, the production of bamboo winding composite pipe reached 10 million tons, all welded pipe can replace 33.6 million tons of welded pipe, can replace 45 million tons of crude steel, save 72 million tons of iron ore, reduce carbon dioxide 83 million tons. The annual carbon sequestration of 1 hectares of bamboo is as high as 5.09 tons, 1.46 times times that of fir and 1.33 times times that of broad-leaved forests. Each plant that is regularly felled can store an extra 10.753 kilograms of carbon than its own growth and extinction. By 2020, 10 million tons of winding composite pipes will require 25 million tons of bamboo, reducing 4.78 billion strains of bamboo, storing 51.32 million tons of carbon and achieving 23.52 million tons of carbon dioxide storage. China has 110 million tons of unused bamboo resources and about 21 billion plants. If all used in the bamboo winding industry, can store 230 million tons of carbon, can store 100 million tons of carbon dioxide.
