API 650 aluminum tanks flush-type cleanout fittings

Natural ventilation loss: the main cause of natural ventilation loss is that the API 650 aluminum tanks is not tightly sealed. This is usually due to corrosion perforation on the top of the oil tank, or there is a height difference between the two orifices. The air tightness of the mixture in the API 650 aluminum tanks is higher than that of the air, which causes the mixture gas in the tank to be discharged into the atmosphere from the lower hole, and the external air flows into the tank from the high hole, resulting in natural ventilation loss.In addition to the requirements of API Standard 620 tank Appendix Q.8.1, the nameplate shall be attached to the tank at an accessible location if it is outside of any insulation or protective covering of the tank. The nameplate for the inner tank shall be located on the outer tank wall but shall refer to the inner tank. The nameplate, if any, for the outer tank of a double-wall tank shall be located adjacent to the nameplate or the inner tank and shall refer to the outer tank.This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API 650 aluminum tanks design, supply fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached datasheets and/or drawings.The company has always adhered to the corporate purpose of “improving benefits, creating wealth, benefiting employees, and giving back to the society”.
