35CRMO seamless Specifications: 6-1240 × 1-200mm35CRMO seamless OCTG imports to total imports from Japan more than half. China's largest oil casing production base - Tianjin Pipe Company in 2000, out of 522,000 tons of steel products, including oil casing 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, seamless (including OCTG) of the existing production capacity already exceeds demand. Therefore, 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 import t91 alloy tube, increase domestic steel enterprises is the key to increase market competitiveness of domestic enterprises and the WTO after long-term task and successful development. T91 alloy pipe prices 5 production of high pressure boiler tube business is: Chengdu Seamless Steel Tube Plant, using Pilger pipe mill, mainly produces large diameter P22,12Cr1MoV, P91 and T91 small diameter boiler tubes; Hengyang Steel Tube Factory, horizontal and even Wall t91 alloy slab by rolling pipe mill, the main production 12Cr1MoV boiler tubes; Shanghai Steel Plant, using precision pipe mill t91, mainly the production of small diameter T91 and G102 boiler tubes; Beiman Special Steel Co., Ltd. of Island t91 alloy , using precision pipe mill, the main production and G102 12Cr1MoV small diameter boiler tubes; Wuhan Heavy Forging Co., Ltd., Japan's second-hand units large pipe jacking equipment, the main production P22,12Cr1MoV, A106B large diameter boiler tubes low thermal conductivity of steel heating slower domestic subcritical pressure natural circulation boiler membrane water wall tubes welded fins, fin flat thick 6mm, 12mm wide import t91 alloy tube, Katherine source of steel (certified), Dagang t91 by Liaocheng Katherine source Pipe Limited.
