Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development in China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! ===================== Steel for LNG receiving stations produced domestically for the first time Time: 2016-01-07 Source: China Energy News Recently, the 304/304L stainless steel slabs used in China’s first floating LNG project – the Sinopec Tianjin LNG receiving station – were fully rolled at Baosteel’s special steel rolling mill. Over 50% of the slabs specified in the contract have been delivered, and all of them meet the customer’s requirements; thus, delivery can be carried out according to the planned schedule. 304/304L stainless steel plates are used in LNG receiving stations; they can operate at temperatures as low as -196°C. The material is required to have excellent corrosion resistance and toughness at ultra-low temperatures, in order to effectively prevent catastrophic brittle fracture. The successful completion of this contract ended the previous reliance on imports for this product, and Baosteel Special Steel has now become the only company in China capable of producing steel for LNG transmission pipes. Three years ago, Baosteel’s Special Steel Manufacturing Department and its Stainless Steel Technology Center formed a joint task force to keep track of the construction of domestic natural gas receiving stations and to carry out active research and development efforts. Through comparisons of domestic and foreign products as well as laboratory research and analysis, the \"Technical Specifications for Austenitic Stainless Steel Sheets and Strips for LNG Receiving Stations\" were drafted. Large-scale production trials were carried out in September 2014, and relevant authoritative institutions were commissioned to evaluate the weld pipe properties of the trial-produced sheets; the results met the requirements regarding the width of ultra-wide stainless steel sheets used for LNG applications.
