How to test bottom seams of API Std 650 flexible liquid storage tanks
The thickness of the overburden on the top of the API 650 oil tank should not be less than 0.5m. The surrounding backfill with clean sand or fine soil should be no less than 0.3m thick; the API 650 oil tank API Std 650 flexible liquid storage tanks operation platform ladder selection unit is considered in a unified manner. The buried operation well is designed for buried horizontal oil tanks, and the two are compatible.
Testing the Outer Tank: While the test pressure is being held, all welded seams and connections in the outer shell and roof shall be thoroughly inspected with a solution film unless they were previously checked with a vacuum box. The API Std 650 flexible liquid storage tanks air pressure shall be released. Pressure relief and vacuum relief valves shall be checked by applying the design gas pressure to the outer tank, followed by evacuation of the outer space to the vacuum setting of the relief valve.
The factors affecting the "small breathing" loss of API Std 650 flexible liquid storage tanks are: 1. It is related to the change of temperature difference between day and night. The greater the change of temperature difference between day and night, the greater the loss of "small breathing"; on the contrary, the smaller the change of temperature difference between day and night, the smaller the loss. 2. It is related to the sunshine time of the oil storage tank. The longer the sunshine, the more the "small breathing" loss; otherwise, the less the loss.
The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve API Std 650 flexible liquid storage tanks work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
