The “12th Five-Year Development Plan” clearly stated that by 2015, the total length of oil and gas pipelines will exceed 150,000 kilometers, which will be 90% higher than in 2010. It is expected that in the next four years, China will need about 700-800 million tons of welded pipe per year in the oil and gas transmission pipelines, of which X80 steel grade is about 5 million tons, and X70 steel grade demand is about 3 million tons; and during the “12th Five-Year Plan” period, China’s oil and gas pipelines The annual demand for SSAW (spiral submerged arc welded pipe) will exceed 5 million tons, and LSAW (straight submerged arc welded pipe) annual demand will be more than 2 million tons.
During the "11th Five-Year Plan" period, the construction of China's oil and gas pipelines continued to develop rapidly, especially with the rapid increase in natural gas demand, natural gas pipelines became the focus of pipeline construction. By the end of the “Eleventh Five-Year Plan” period, China has accelerated the deployment of the oil and gas pipeline network. The oil and gas backbone pipeline network covering the entire country has been initially established, and China’s oil and gas supply support capacity will be further enhanced in the future. The data shows that as of the end of 2010, the total length of oil and gas pipelines built in China was approximately 85,000 kilometers, including 45,000 kilometers of natural gas pipelines, 22,000 kilometers of crude oil pipelines, and 18,000 kilometers of refined oil pipelines, forming a cross-border east-west and north-south direction. Covering the national and overseas oil and gas pipeline grids.
