In view of the fact that the loading and unloading arm such as land liquefied petroleum gas(LPG)and liquefied natural gas(LNG)is a non-standard product,and it is affected by factors such as wind and sun,external temperature changes,acid rain erosion,internal medium,impurity corrosion and other factors for a long time,and gradually exposes various safety hazards with the extension of service time.This paper finds several problems through the inspection of the loading and unloading arm in use,including uneven factory quality,serious rain erosion,galvanic corrosion of components,installation defects,and the existing inspection procedures are not targeted for the loading and unloading arm.For the lack of pertinence of the loading and unloading arm inspection items,this paper puts forward the key inspection content and inspection cycle of the loading and unloading arm according to the failure characteristics of the loading and unloading arm.
