我国自行设计、制造的国内目前重量最大的高压加氢反应器于1991年6月12日由中国石油化工总公司第三建设公司在浙江镇海石化总厂加氢裂化装置现场一次吊装就位成功。这台反应器是大型炼油装置中加氢裂化的关键核心设备,设计压力18.09MPa,设计温度427℃,设备直径3.636m,高34.4m,壁厚218mm,主体材质为2(1/4)CrlMo,采取筒节锻焊热壁式结构,内壁为TP309L与TP347L不锈钢堆焊,堆焊厚度8mm,设备本体达583.81t,投资4千万元。该设备
China’s own design and manufacture of the current weight of the largest domestic high-pressure hydrogenation reactor on June 12, 1991 by the China Petroleum & Chemical Corporation Third Construction Company in Zhejiang Zhenhai Petrochemical Plant hydrocracking unit site a successful installation. This reactor is the key core equipment for hydrocracking in a large refinery. The design pressure is 18.09MPa, the design temperature is 427 ℃, the equipment diameter is 3.636m, the height is 34.4m, the wall thickness is 218mm, and the main material is 2 (1/4) CrlMo , To take the tube forging welded hot wall structure, the inner wall of TP309L and TP347L stainless steel surfacing, surfacing thickness of 8mm, the device body of 583.81t, an investment of 40 million yuan. The device
