API Std 650 self-anchored flat-bottom steel tanks testing of the roof

Personnel organization before the construction of the API Std 650 self-anchored flat-bottom steel tanks:
The company shall select technical personnel, quality inspectors and material personnel with organizational ability and construction management experience to participate in the API Std 650 self-anchored flat-bottom steel tanks project construction. The construction personnel shall arrive at the construction site before the designated commencement date, investigate the construction site, build construction facilities, plan the construction steps, and analyze the potential safety hazards during operation.

Allowable Design Stresses
The maximum allowable design stresses for the API Std 650 self-anchored flat-bottom steel tanks materials outlined in Q.2.1 shall be in accordance with Table Q-3.The values for the allowable design tensile stress given in Table Q-3 for materials other than bolting steel are the lesser of (a) 331/3% of the specified minimum ultimate tensile strength for the material or (b) 662/3% of the specified minimum yield strength, but they are 75% of the specified minimum yield strength for the stainless steel, nickel alloy, and aluminum materials. Allowable test stresses are based on the limitation of API 620 oil tank storage standard Q.8.1.3.

API 650 petroleum storage tank has the advantages of high safety: the API Std 650 self-anchored flat-bottom steel tanksinner floating plate floats on the liquid surface, so that the liquid phase has no evaporation space, which can reduce the evaporation loss by 85% to 90%. At the same time, the API 650 petroleum storage tank blocks the air and liquid storage through the floating disk, which reduces air pollution and reduces the degree of fire risk.

Firmly establish the "people-oriented, safe development" concept, strictly follow the safety production policy of "safety first, prevention first, comprehensive management", strengthen and improve the management and supervision of safety production in an all-round way, and strive to improve the controllability of safety management And effectiveness, cultivate safety culture, improve long-term safety production mechanism, and build a harmonious BEBON.
