National Direct double-wall tank

Tank transport to focus on safe, reliable, and comprehensive consideration of various factors, not only that double-walled storage tanks, but also pay attention to the oil tank inspection, the most important thing is flush test tank, the following specific brief. First, at present, in order to facilitate the transport of oil, heavy oil and crude oil in the storage tank and a heater double tanks, the ground outside of the tank wall insulation measures should be taken. According to the production, maintenance and safety requirements with a tank: 1, amount of hole (doubles sampling hole); 2, storage of gasoline, kerosene, light diesel oil, crude oil and aromatics tanks tank, set the breathing valve; 3, heavy fuel oil storage tank, raw oil, heavy diesel oil and gas oil, etc., need to set the ventilation holes; 4, manholes, and cleaning aperture hole (the latter set up only in the heavy tanks) . Second, after the completion of the tank must be filled with water test, the main objectives are: reliability test tank structure; check leakage; pre-press foundation. On soft ground to strictly control the water filling rate, the tank of the settlement will not be too fast, keeping in mind the changes in the surface soil around the tank double oil plant, to avoid shear failure foundation. Tank construction from the foundation over a period of time, to continuously carry out settlement observation work until after the operation. For floating roof tanks, but also for floating roof lifting test. Filled with water and turn on the water should be in the focus of inspection floating roof and down smoothly, sealing flexibility and the guide portion, the central drain leakage and the like.
