Refining equipment routine maintenance new methods, extend equipment life With mixed now refining equipment industry , more and more hydraulic oil press failure during operation , which allows oil equipment customers are very anxious to have the phone hydraulic oil press manufacturers advice on how to improve the life of the oil refining equipment. In fact , extend the life of the equipment has one of the most important ways is to pay attention to the usual maintenance and upkeep. Routine testing refining equipment , oil refining equipment of various types of pipes for external examination at least once a year , at least once every six years, a comprehensive inspection  I, Ⅱ, Ⅲ class pipe at least once a year to check focus , Ⅳ, Ⅴ class pipe at least every 2 years conduct a focused inspection. External inspection pipe outer surface of the pipe is mainly observed for cracks , corrosion and deformation and other defects, whether the partial opening connecting flanges , fasteners are complete, whether corrosion, loose and so with the internal auditory canal sound method to check whether the foreign the impact and friction sound like. In daily life, daily maintenance , while seemingly cumbersome, but also refining equipment failure to timely repair , improve the efficiency of the overall production . In the long run , is still very necessary .
