针对国内3LPE/PP防腐管管端钢丝刷打磨工艺的缺陷和不足，开发了3LPE/PP防腐管管端涂层切削装置及处理工艺，实现了管端PE/PP涂层坡口角度和预留FBE涂层宽度的精确控制，为现场节点防腐施工提供良好的粘结与兼容性，提高了管道节点现场的补口质量，在中海油多个工程项目中进行了应用。
針對國內3LPE/PP防腐管管耑鋼絲刷打磨工藝的缺陷和不足，開髮瞭3LPE/PP防腐管管耑塗層切削裝置及處理工藝，實現瞭管耑PE/PP塗層坡口角度和預留FBE塗層寬度的精確控製，為現場節點防腐施工提供良好的粘結與兼容性，提高瞭管道節點現場的補口質量，在中海油多箇工程項目中進行瞭應用。
침대국내3LPE/PP방부관관단강사쇄타마공예적결함화불족，개발료3LPE/PP방부관관단도층절삭장치급처리공예，실현료관단PE/PP도층파구각도화예류FBE도층관도적정학공제，위현장절점방부시공제공량호적점결여겸용성，제고료관도절점현장적보구질량，재중해유다개공정항목중진행료응용。
In view of deficiency of domestic steel-wire brush grinding method for anti-corrosion coating end, equipment and treatment technology of cutting process for 3LPE/3LPP anti-corrosion coating end are developed, and bevel angle of PE/PP coating and FBE tail length can be controlled precisely. Excellent bonding and compatibility can be achieved during field joint coating toimprove the quality of operation, which has been successfully applied in several pipeline projects of CNOOC.
