Hengyang Valin steel tube co., Ltd. (abbreviation for-steel) attached to Hunan Valin iron and steel co., Ltd., is the world's largest seamless steel pipe production enterprise, China's second largest professional manufacturer of seamless steel pipe. founded in 1958 and currently employs 5,400 people, including professional and technical personnel more than 2000 people, with a total asset of 13.4 billion yuan. Enterprise of development get successive party and national leaders of height attention, Qiao, and Zhu Rongji, and Wei, and Wu guanzheng, and Zeng Peiyan, and Liu Yunshan has visit inspections, on scales steel of development giving full certainly, enterprise has obtained national "51" labor awards, and national x publicity typical enterprise, and national equipment management advanced units, and national heavy contract faithful with advanced units, and national factory works open Advanced units, and Hunan province civilization pacesetter units, and Hunan province gardens units, honors title.

scales steel firm to implementation technology Hing enterprises strategy, constantly introduced, and digestive, and absorption world seamless area of advanced equipment and tip technology, now has ' 50, and ' 89, and ' 180, and ' 219, and ' 340, and ' 720, 6 article pipe line, and 2 article tube processing line, and 3 sets round tube billet production system, and 1 sets BF ironmaking system, With an annual output of 900,000 tons, 1.5 million tons of steel, 2 million tons of iron pipe, 100 million tons of processing capabilities, is the world's most seamless steel tube production line, supporting the most advanced models, the product specification of the enterprise. ' ' ' 89, 180, 340 of which are State of the art rolling pipe mill; ± 720 unit is now the largest-diameter-pipe rolling unit cycles. in Hunan province pioneered with the enterprise as their main body construction of industrial parks, steel processing industry zone is new industry demonstration base of industrialization of the country.

value for money is now capable of producing steel ' 720mm the following varieties of each kind of specification, hot-rolled, cold-drawn seamless steel pipe, passed ISO9001 quality and ISO14001 environmental, OSHMS on occupational safety and health, the ISO10012 measurement management system certification, ISO17025 testing and calibration of the five, and through special equipment pressure piping components, API (5CT\5L\5DP), such as PED and CPD the product quality certification and the United Kingdom, and Norway factory authorized eight classification society, and by Chevron, shell, total, second-party approval of dozens of internationally renowned companies such as, quality of products enjoy a high reputation at home and abroad, domestic oil, power generation, petrochemical, boiler, machinery, coal, chemical and other industries have established stable marketing channels. the export zone covers the world's major markets, exporting more than more than 60 countries and regions, export volume and export rate has been steady in the forefront of the domestic counterparts.

2008 years after the outbreak of the international financial crisis, seamless steel pipe industry faces adverse factors such as macro-economic situation is grim and overcapacity, hang steel positive change in mode of development to vigorously implement efficiencies, reducing debt and negative, significant cost reductions, substantially optimized environment dramatically improved, and intrinsic competitiveness of enterprises further tamped. adhering to innovation-driven development, increasing investment in research and development to create a "creative type Heng steel", a national high and new technology enterprises, national pilot enterprises and intellectual property rights, intellectual property model enterprise of Hunan province. promoting structural adjustment, and formed a "production generation, reserve generation, developed generation" product innovation pattern and realize China's home-made pipe, steel tubes for nuclear power production batch.
