The new Xinjiang coal-to-gas pipeline project (including the new Guangdong-Zhejiang Pipeline and Xinlu Pipeline) invested by Sinopec is being launched.The demand for slurry pipeline is a new highlight of foreign tradeIn 2013, China's steel pipe foreign trade has made great progress. The development of natural gas has promoted the booming construction of oil and gas long-distance pipelines in many regions of the world. The newly started housing area is 2.8-10 trillion yuan, a year-on-year increase of 15%-17. In addition, from the perspective of national policy, the popularity of plastic pipes is increasing, and the living space of steel pipes is being squeezed.09 billion square meters - 2. For example, the X70 steel grade and 18-meter-long slurry welded pipe produced by WIW660 Steel Pipe Plant of Wuhan Gangbei Company of Wuhan Iron and Steel Co.

Increasing the amount of clean energy will make the oil and gas pipeline become the highlight of the steel pipe market demand, driving the rapid growth of steel pipe production. It is estimated that China's natural gas production will reach 131 billion cubic meters in 2014, and crude oil production will reach 220 million tons. Among them, seamless steel pipe 5. It is expected that the national economy will stabilize and rebound in 2014, infrastructure investment will continue to grow, and urbanization will accelerate the pace of industrialization, which will drive the demand of the machinery industry to pick up.5%.5 million tons. was exported to Australia and applied to the slurry conveying pipeline project in Papua New Guinea. At the same time, China's machinery product ownership has reached a large scale, product replacement and maintenance and repair will increase significantly. The national real estate development investment was 860.5 million tons of oil-specific pipes, roughly the same as the amount of line pipe used in 2013. The investment in real estate development is 9. In addition to the pipelines under construction, the planned pipeline length is 143,000 kilometers, of which 75% is natural gas pipelines, and the future world oil and gas special pipeline market remains. China's steel pipe enterprises are not only exporting steel pipes in foreign trade, but also exporting steel pipe equipment and technology.Oil and gas pipeline pipe usage is flatIn the case of a moderate global economic growth, the international oil and gas market will show three characteristics of oil demand growth in steadily, oil supply will continue to increase rapidly, and the US dollar will strengthen oil prices.13 billion square meters, an increase of 6%-8% year-on-year. It is one of the three major steel products (cold plate series, hot plate series, pipe series), and its export focus is Southeast Asia, Middle East and North America.Comparative analysis of downstream application areas of steel pipes and plastic pipesAs we all know, China's steel pipe industry is currently in a serious stage of oversupply.3%. The demand for dependence on the Middle East oil supply has been weakened.

There is room for development. However, due to the obvious increase in trade protectionism, China's steel pipe exports will face more difficulties.In 2013, the machinery industry consumed 133 million tons of steel, a year-on-year increase of 4%.Mechanical steel pipe has reboundedIn 2013, the added value of industrial enterprises above designated size in China's machinery industry increased by 9.2 million tons, 800,000 tons of welded pipes, a total of about 10.permanentsteel.
