70ft diameter API Std 650 larger diameter tanks

Natural ventilation loss: the main cause of natural ventilation loss is that the API Std 650 larger diameter 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 Std 650 larger diameter 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,API Std 650 larger diameter tanks. Pressure-relieving DevicesTanks shall be protected by automatic pressure-relieving devices that will prevent the pressure at the top of the tank from rising more than 10% above the maximum positive gauge pressure except as provided in API 620 standard 9.2.2.Where an additional hazard can be created by the exposure of the tank to accidental fire or another unexpected source of heat external to the tank, supplemental pressure-relieving devices shall be installed. These devices shall be capable of preventing the pressure from rising more than 20% above the maximum positive gauge pressure. A single pressure-relieving valve may be used if it satisfies the requirements of this paragraph and 9.2.1.The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API Std 650 larger diameter tanks API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.The company's quality is first, the price is reasonable, the construction period is guaranteed, and the purpose of abiding by the contract, our steel API Std 650 larger diameter tanks products have received high recognition from customers from the world.
