Around the successful construction of major steel structure

Offshore oil production to reach 100 million tons in 2015, ocean engineering equipment enterprise's goal is to provide 1500 meters to 3000 meters deep mining with a large number of equipment, industry level and scale must be raised; structural steel pipe housing stainless steel shower pipe with green environmental protection, energy conservation and emissions reduction and recycling economy policy, stainless steel shower set the industrialization, standardization of steel structure residential products have broad and unlimited market space; At present, the country's 590000 highway bridge steel structure bridge is less than 1%, the high-speed railway system development, the new line to bridge the generation road, 80% are prestressed concrete Bridges. But China's steel structure industry in industry informatization, since can occupy more market, will be included in the planning and support, and supporting policies. Opportunity is to chooseStructural steel pipe industry in China during recent 10 years rapid development, has become a global steel structure construction, manufacturing capacity, the industrial scale, the strongest enterprise scale with the world's largest steel structure. Around the successful construction of major steel structure, steel structure comprehensive technical level of our country is in the international advanced level. General conditions using carbon steel material, steel structure with seamless steel tube heat treatment including normalizing, tempering, quenching. Heat treatment's main purpose is to remove the magazine, make the internal organization of the pipe body more closely, enhance the mechanical properties of the pipe body. And steel bridge in Japan accounted for 41%, the United States accounted for 33%, so the market demand and industry development of China's steel bridge also has the very big disparity with the developed countries. Mainly for the execution of the standard structure with seamless steel tube is used for general structure and the mechanical structure of seamless steel tube. .Seamless steel pipe for steel structure refers to the action of external force metal strength, the ability to resist plastic deformation and fracture. Seamless mild steel pipe for steel structure according to different structure, using the environment using different material, compressive ability is alloy steel material, high temperature resistance corrosion resistant stainless steel material
