摘要
某炼油厂加氢装置中的冷高压分离器存在湿H_2S严重腐蚀,其壳体应选用ASME牌号SA516Gr65(HIC)材料。基于国内钢板生产的实际情况,新开发了厚度为165 mm的SA516 Gr65(HIC)厚钢板;经设备制造厂对该钢板性能复验、焊接工艺评定及设备制造,表明国产SA516 Gr65(HIC)钢板与国外生产的钢板质量基本相当,可以替代进口钢板作为同类设备的材料。
The cold high—pressure separator of a hydrogenation unit in a refinery is in serious wet H_2S environment.SA516 Gr65(HIC) should be selected as the material for the shell of the separator. Base on the actual circumstance of the manufacture of domestic steel plate,a new thick steel plate SA516 Gr65(HIC) with thickness of 165mm is developed.After verification of the material property,welding procedure qualification and equipment manufacturing by the equipment manufactory,it is indicated that the domestic SA516 Gr65(HIC) steel plate is equivalent to that of the foreign ones and can be used in the similar equipment in place of imported steel plates.
