1 2011 1 王 盟, 唐琳琳 ( 山东博润工业技术有限公司, 山东 淄博 255000) : 介绍了重介选管路常用耐磨材料以及各种耐磨材料复 内衬的耐磨管制造工艺, 并对重介 系统管路的磨损进行了分析, 指出对磨损严重的三通弯头等管件使用氧化铝陶瓷内衬复 管, 对 磨损程度低的直管则使用超高分子量聚乙烯复 内衬耐磨管, 从而延长了重介选煤系统耐磨管路的 使用寿命, 降低了管路系统的运行成本, 减少了检修和材料消耗 : 耐磨管路; 耐磨材料; 使用寿命 : TD942 : B : ( 2011) The introduction and selection of the wearresistant material used f or the heavy medium pipeline in coal preparation plant WANG M eng, T ANG Linlin ( S hand ong B or un I nd ustr ial Te chnolog y Corp orat i on L t d . , Zibo 255000, China ) Abstract: The wearresistant Material used in heavy medium coal preparation pipeline and the production technology of wearresistant Material lined pipes were introduced, and the abrasion of the heavy medium coal preparation pipelines was analysed. It indicated that the Al OCeramicinner lined pipes shouldbeusedin pipe tee and bend where there was moreserious abrasion, the 2 3 super high molecular weight VA inner lined pipes were used in straight pipeline where there was less abrasion. The results showed that the service life of the Wearresistant pipe used in heavy medium coal preparation pipeline was enhanced, the operation cost of the pipeline system was decreased, the consumption of the maintenance cost and the material was reduced.
