Our products are widely used in petroleum, chemical, pharmaceutical, food, energy, electricity, aerospace, environmental protection, boiler heat exchanger and other areas, the company's annual production capacity of 25000 tons of seamless pipe, welded pipe 6000 tons, in 2007 sales of 532700000 yuan, 2012 sales of 312260000 yuan, is the production of China stainless steel seamless pipe leading enterprises, is the president Shanghai Steel Association unit, won the "Shanghai famous brand", "famous brand of stainless steel industry" and "Shanghai famous trademark", become a qualified supplier of BASF, DuPont, Dow Chemical, BP oil, Middle East oil company, the Russian oil company, British Petroleum Company, Canadian Petroleum Corp, PetroChina, Sinopec, CNOOC, China nuclear industry Guodian, solar energy, High-speed Rail, metro rail vehicles. Shanghai Shangshang stainless steel tube company has assets of 400000000 yuan, the company has advanced production equipment and testing equipment, mainly equipped with 76 of the 10 units, punch a cold rolling mill, 17 sets of cold drawn tube machine, 3 large caliber stainless steel welded pipe production line, 3 stainless steel welded pipe production line, 7 consecutive Taiwan stainless steel pipe pressing machine and other major production equipment, and Japanese SHIMADZU PDA5500 II spectrometer a metallographic microscopic photography, Chua's German RWES-600B material testing machine, JB-300B pendulum impact testing machine, ETS-57 and ETL-159 testing eddy current line, UTL108 ultrasonic inspection spiral line, UTS530 ultrasonic flume a, X ray inspection line, 114-530 and Phi Phi 25-89 hydraulic testing machine 2 sets of modern testing equipment, products strictly according to national and foreign standards organization of production. Company production of "Ferritic Austenitic duplex stainless steel tube and its manufacturing process" by the invention patents, patent No. ZL200710044273.6; austenite ferrite duplex stainless steel seamless steel pipe by the Shanghai Municipal Economic Commission held a new technology identification, identification certificate number: Shanghai by means of words 2008-90-008; austenite ferrite double phase stainless steel seamless steel pipe by the Shanghai Municipal Science and technology achievement certificate, certificate number: 9312008Y0363; AUSTENITIC FERRITIC duplex stainless steel tube was identified as transformation projects, Shanghai hi tech project number: 200803122, project grade A, technical contribution coefficient is 0.9; AUSTENITIC FERRITIC duplex stainless steel seamless steel pipe for 2008-2009 national torch plan project, project no.:
2008GH030202; austenitic iron Mr.Zhou body double phase stainless steel seamless steel pipe was rated as Shanghai key new product, project number: 08XP0513600. Therefore, our company and Shanghai Jiaotong University School of materials science and engineering, Qiangqiang jointly established the stainless steel heat pipe engineering technology research center, enterprise technology center was identified as municipal technology center, identified symbol: Jia (2007) No. 53.
Austenite ferrite dual phase stainless steel is in roughly the same proportion of austenitic phase and iron ferrite phase and Austenitic - ferrite body dual phase stainless steel both iron ferrite and austenitic stainless steel mechanical properties of characteristics, both high strength and good toughness and weldability, dual phase steel also resist chloride should stress corrosion, pitting resistance, applicable to resistant to dilute sulfuric acid, resistance to dilute hydrochloric acid and phosphoric acid and various chloride aqueous solution of corrosion resistance. With the development of oil and gas extraction industry and chemical industry, some corrosion resistant pipes are urgently needed.. If found worldwide large gas fields in the east of Sichuan area, China, but natural gas containing large amounts of H2S, CO2, SO2, Cl2 gas, for steel corrosion is very serious, due to steel corrosion and leakage of the accident had occurred. For 304L (00Cr19Ni9) of the, 316L 00Cr18Ni14Mo2 etc. stainless steel cannot afford the corrosion of H2S, CO2, SO2, Cl2 gas, there is an urgent need to develop a high corrosion resistance of duplex stainless steel seamless steel pipe, the need to adapt to the development of oil and gas exploitation industry and chemical industry. With the exploitation of offshore oil, oil gas pipelines in the sea water is increasingly. Due to seawater containing large amounts of Cl - ion, the pipe corrosion, 304L 00Cr19Ni9, 316L 00Cr18Ni14Mo2 etc. so are not under Cl - ion corrosion, also need to develop the high corrosion resistance of duplex stainless steel seamless steel pipe, in order to meet the needs of offshore oil drilling. Because the duplex stainless steel than the ordinary stainless steel strength 1, the service life extension 19.23% times above, is the outstanding material product. Company production of "high pressure boiler heat exchanger with stainless steel seamless steel pipe manufacturing process" by the invention patents, patent No. ZL200810034602.3; high pressure boiler, boiler and heat exchanger by the Shanghai Municipal Economic Commission held a new technical appraisal of new products will use stainless steel seamless pipe, identification card number: Shanghai by means of words 2008-90-009; high pressure boiler, the boiler and heat exchanger by the Shanghai Municipal Science and technology achievement certificate, stainless steel seamless tubes for certificate number: 9312008Y0364; high pressure boiler, boiler and heat exchanger of stainless steel seamless pipe in Shanghai city was identified as high-tech achievements into the project results, project number: 200807426, project grade A, technical contribution coefficient is 0.9; high pressure boiler, boiler and heat exchanger for Shanghai key new products of stainless steel seamless pipe, project.
