API standard 650 larger diameter tanks fabrication

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of API standard 650 larger diameter tanks service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.Bearing on Foundations
Foundations shall preferably be designed to resist the load exerted by the API Standard 620 tank and its contents when the tank is filled with water to the design liquid level. Foundations shall be designed at least for the maximum operating conditions including the wind load. During the API standard 650 larger diameter tanks water test, the total load on the foundation shall not exceed 125% of the allowable loading. If necessary, the water level during the test may be reduced below the design liquid level line so as not to exceed the 25% maximum overload (see Q.8.1.2).Selection of nominal diameter D of API 650 storage tank. In the design calculation of API 650 storage tank, the bottom plate thickness is the net plate thickness, that is, the actual thickness minus the corrosion allowance. In the design and calculation of API standard 650 larger diameter tanks wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.The company has always been adhering to the business philosophy of "integrity-based, responsibility oriented, quality first, reputation first" and is committed to building a world-class steel materials and service provider. We will continue to work hard to carry forward the enterprise tenet of "quality is the life of the enterprise, survival by quality, development by reputation", and become an enterprise with strong vitality! We always keep it in mind that profit is important to enterprises. But what counts more is social responsibility.The main reason of "small breathing" loss of API standard 650 larger diameter tanks is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API standard 650 larger diameter tanks also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API standard 650 larger diameter tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
