world production Seamless 110

Seamless pipe (Seamless tube) is a kind of hollow cross section, no seams around the steel strip. At present, total world production Seamless 110 of more than 1850 companies in many countries under the more than 5100 factories, which produce the oil tube 44 countries, more than 170 companies under more than 260 plants. In 2000, the national apparent consumption of seamless pipe 4.18 million tons, of which the domestic supply of 3.821 million tons, accounting for 91.4% of total domestic demand. Imported 35.9 million tons, accounting for 8.59% of total domestic demand. In the same year the oil consumption of about 910,000 tons tube. Import about 252,000 tons. Inlet tube total domestic consumption of about 70%, of which imports of pipe total domestic consumption of 27.69%, oil imports accounted for about seamless tube of total imports about 70%. Oil pipe imported from Japan imports more than half of the total. China's largest production base of oil casing - Tianjin Steel Tube Company's steel products in 2000 came to 522,000 tons, which produced 364,100 tons of oil casing. Casing accounting for more than half of oil production. Both production and sales in China accounted for the first casing market. From the perspective of international and domestic markets, seamless (including OCTG) are greater than the needs of the existing production capacity. Therefore, future emphasis should be placed on the capacity of full play to existing units, to develop high strength, high-combat damage, high resistance to corrosion of oil pipes, high pressure boiler tubes and cylinder pipes and other products. Is also the national steel market in China for the current product mix optimized content. This is to increase competitiveness in domestic and foreign products, the key to expanding market share. That is, the domestic steel companies to improve the market competitiveness of domestic enterprises after WTO plus and the long-term task and the key to successful development.
