API 650 carbon and low-alloy steel tanks snow load

BBN employees work hard and work hard in their work. In life, colleagues care about each other, like a family, and accompany each other at important moments in life. BBN Steel organizes employees to carry out tourism activities every year, so that families can be exposed to nature and relax physically and mentally. The good combination of working and rest can achieve the goal of hard work and happy life.When the anchorage is designed to meet the requirements of API Standard 620 tank Q.3.6.4.2, the foundation should be designed to resist the uplift that results from three times the design pressure with the tank full to the design liquid level. When designing to any of the conditions in this paragraph, it is permissible to utilize friction between the soil and the vertical face of the ringwall and all of the effective liquid weight.The tank wall design of API 650 oil storage tank. Since there is no ventilation pipe directly connected with the outside on the top of the API 650 carbon and low-alloy steel tanks tank, the ventilation between the inside and outside of API 650 oil storage tank is realized by the respiration valve. The constant pressure of the respiration valve is 0.3kPa, so the pressure on the top of the tank is 0.3kPa.Enterprise mission: to create value added steel products API 650 carbon and low-alloy steel tanks and provide first-class serviceWe are committed to quality. It is to firmly establish the concept that quality is the life of an enterprise, and make it clear that quality is the decisive factor for the survival and development of an enterprise. Adhere to the quality brand strategy and strive to improve the comprehensive competitiveness with quality as the core.Core values of the enterprise: innovation, dedication and transcendence. It is a highly refined spiritual quality to our staff.When the day light gradually decreases, the temperature of oil in the API 650 carbon and low-alloy steel tanks will also decrease, the evaporation speed will gradually slow down, and the pressure in the API 650 carbon and low-alloy steel tanks will also decrease. When the pressure in the API 650 carbon and low-alloy steel tanks is lower than the negative pressure rating of the breathing valve, the outside air is sucked into the API 650 carbon and low-alloy steel tanks through the open vacuum valve, which is the "suction" process of the oil tank.
