Angang X90 single-furnace trial production plate coils and steel pipes passed* * Authoritative unit for oil pipe testing, CNPC Engineering Materials Research Institute * * The inspection and evaluation by the Oil Pipe Quality Supervision and Inspection Center indicates that Anshan Iron and Steel has the technical capabilities to produce ultra-high-strength X90 pipeline steel. 　　In order to reduce pipeline construction costs and increase the transportation capacity of a single pipe, the use of high-strength and ultra-high-strength pipeline steel with large pipe diameters, large wall thicknesses, and high-pressure transportation has become a development trend in new pipelines. This puts forward higher requirements for the strength, toughness, thickness and width specifications of steel materials. At present, X90 is highly praised by the industry as a new generation of steel grade products that is about to be promoted, and it is also a key product developed by Anshan Iron and Steel Co., Ltd. in recent years. 　　With the help of the technological exploration in the laboratory of the Ansteel Group Iron and Steel Research Institute and the support of the 2150 production line equipment upgrade and transformation of Ansteel Co., Ltd.'s hot-rolled strip steel plant, Ansteel Co., Ltd. successfully completed the single-furnace trial production of ultra-high-strength X90 coils. The product specification is 16.3 mm × 1550 mm. Three of the coils were successfully made into large-diameter spiral submerged arc welded pipes, and passed the inspection and evaluation. 　　"China Metallurgical News" (page 01, April 15, 2022)
