- 针对法兰密封面中径偏差超标和表面粗糙度不符合要求的情况，介绍一种使用研具对密封面进行研磨从而使密封面达到要求的方法，分别从研具和研磨剂的选择、研磨的步骤及研磨的技术要求等方面进行了详细的说明。采用该方法对大庆油田化工总厂20万t/a催化脱蜡及加氢精制装置中梯形槽密封面中径超标的法兰进行了处理，取得了很好的效果。
In connection with that the mid diameter deviation exceeds standard on flange seal face the surface roughness is not in keeping with requirement, the paper introduces a method to grind seal face with one kind of grinding tools and to make the seal face qualified. The selection of grinding tool agent, the grinding procedure the technology requirment of grinding etc. aspects were explained in dedail. It has acquired a very good effect to dispose the mid diameter deviation exceeded standard on trapezoidal groove seal face flanges used in the 20×10 4t/a catalytic dewaxing hydrofining unit with this method in Daqing Oilfield Petrochemical General Plant.2001,6(6): 52-53,56 收稿日期：2000-12-4作者简介：张风光，经济师。1987年毕业于西安石油学院，现从事工程项目管理工作。通讯地址：山东省胶州市，邮编：266300
