API 650 self-anchored flat-bottom steel tanks bleeder vents
This standard only applies to API 650 storage tanks API 650 self-anchored flat-bottom steel tanks with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).
For all API 620 crude oil tank other materials, the impact test temperature shall be at least 30°F colder than the design metal temperature. Alternately, materials impact tested at the design metal temperature or lower with Charpy impact test energy value of 25 ft-lb (average), 20 ft-lb (minimum) are acceptable for design metal temperatures above –40°F. API 650 self-anchored flat-bottom steel tanks materials with an energy value of 30 ft-lb (average), 25 ft-lb (minimum) are acceptable for design metal temperatures of –40°F or lower.
Static storage loss is also known as "small breathing" consumption. The rise and fall of the temperature in the API 650 self-anchored flat-bottom steel tanks leads to the increase and decrease of the pressure in the tank, which makes the mixed oil gas discharged from the tank, and the external air is sucked into the tank, resulting in the oil consumption. Fluid level loss is also called "big breathing" loss. It is the oil consumption caused by the change of gas space volume in the API 650 self-anchored flat-bottom steel tanks during the oil receiving and sending operation, which causes the mixed oil gas to be discharged out of the tank, and the external air is sucked into the tank, resulting in the oil consumption due to the change of liquid level height.
Customer concept: customer first. Guided by market changes and guided by customer needs, we design the optimal product solutions and provide the best after-sales service. Partners: to reach a balance of interests with all stakeholders, to build a harmonious coexistence and win-win cooperation.
The mode of iron and API 650 self-anchored flat-bottom steel tanks steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API 650 self-anchored flat-bottom steel tanks steel logistics.
