API Std 650 unanchored tanks operators

BBN is a big team with great centripetal force. The company adheres to the tenet of "creating value for customers, creating benefits for enterprises, creating wealth for employees, and creating prosperity for society". Adhere to the strict management of factories, technology-oriented, adhering to "standard management, adhere to integrity, the pursuit of excellence, pragmatic innovation "Business philosophy, we are committed to creating a full-process, low-cost, high-quality, green and environmentally friendly stainless steel manufacturing enterprise.Aftershock Level Earthquake (ALE)
This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.
If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API Std 650 unanchored tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.Oil, Gas, Chemical, Water, and Bio-Fuel storage. Maximum of the most common welded steel tanks used in industry are designed following API 650. Tanks typically found in Refinery API Std 650 unanchored tanks tank farms, Terminals, Pipelines, and other process facilities use these tanks.The work concept attaches importance to talents, creates a high-income and high-standard employment mode and work mode, actively advocates all kinds of talents to inspire each other, respect each other, unite and act together, cultivates employees' corporate interests above all else, is tolerant and enterprising, learns correct ways of doing things, improves employees' Professional quality, encourages and urges employees to make continuous progress, Continuously realize self value and grow together with the enterprise.The main reason of "small breathing" loss of API Std 650 unanchored 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 Std 650 unanchored 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 Std 650 unanchored tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
