Domestic seamless steel pipe heat treatment Adds New Changes
Domestic seamless steel pipe heat treatment added a new change, with major steel seamless steel heat treatment include normalizing, tempering, quenching. The main purpose of heat treatment is to get rid of the magazine, the tube inside the organization more closely to enhance the mechanical properties of the tubular body. Steel seamless steel pipe refers to the metal in the external force, the ability to resist plastic deformation and fracture. The main implementation of standards (GB / T8162-2008) seamless steel structure seamless pipe for general structure and mechanical structure. Depending on the steel structure, the use of the environment with the use of different materials seamless steel tubes, high temperature capability is under pressure alloy steel, corrosion resistant stainless steel.
Offshore oil production in 2015 to reach 100 million tons, marine engineering equipment business goal is to provide a large number of deep-sea equipment for the 1500 meters to 3000 meters in mining, industry must improve the level and scale; steel housing line with environmental protection, saving energy and reducing discharge cycle and economic policy, industrialization, standardization steel housing products have broad and unlimited market space; At present, 590,000 highway bridges in less than 1% steel bridges, high-speed railway system development, the new line by bridge 80% are pre-stressed reinforced concrete bridges. The Steel Bridge in Japan accounted for 41 percent, the United States accounted for 33%, we can see that China's steel bridge market demand and industrial development there is a big gap with the developed countries.
Success around major construction projects of steel, shows that China's steel integrated technical level has been at the international advanced level. However, China's steel industry in information technology, since the market can occupy more industries will be included in the planning and support, support policies.
Chinese steel industry has developed rapidly during the past 10 years, has become a global steel manufacturing capacity of the strongest construction, steel big country industrial scale, the scale of business.
