35CRMO seamless Specifications: 6-1240 × 1-200mm35CRMO seamless OCTG imports to total imports from Japan more than half. China's largest oil production base casing - Tianjin Pipe Company in 2000, out of 522,000 tons of steel products in Tianjin t91 alloy pipe, oil casing which production was 364,100 tons. Casing accounting for more than half of the country's oil production. The production and sales are accounted for first Chinese casing market. From both the international and domestic market, Wall t91 alloy seamless pipe (including OCTG) of the existing production capacity already exceeds demand. So import t91 alloy tube, the future focus should be on full capacity of existing units, the development of high-strength grade, high combat destroyed, high resistance to corrosion of oil pipes, high pressure boiler tubes and cylinders pipe and other products. National content is optimizing product mix for the current China's steel market. This is also an increase in the competitiveness of domestic and foreign products, expand market share in the key lies. That is, to raise domestic steel companies increase market competitiveness is the key to domestic enterprises and the WTO after long-term task and successful development. 35CRMO seamless steel pipe and the general application of a fluid with seamless steel pipe: GB8163-992, boiler seamless steel pipe: GB3087-19993, high pressure boiler seamless pipe: GB5310-95 (ST45.8-Ⅲ type) 4 , fertilizers, equipment, high pressure seamless steel: GB6479-19995, geological drilling seamless: YB235-706, oil drilling seamless: YB528-657, petroleum cracking seamless steel pipe: GB9948-888, oil drill collar special Seamless: YB691-709, car axle seamless steel pipes: GB3088-199910, ship with seamless steel pipe: GB5312-1999 t91 alloy 42X5, Dongli District t91, Katherine source of steel provided by Liaocheng Katherine source Pipe Co., Ltd. .
