A516 Gr 55 plates API 650 closed top welded storage tanks
Allowable Design StressesThe maximum allowable design stresses for the API 650 closed top welded storage 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.
The API 650 specification provides guidelines for the API 650 closed top welded storage tanks design, manufacturing, materials, installation and inspection of welded vertical and cylindrical tanks. Such containers must be on the ground and have a closed or open top.
The hot weather in summer brings great security challenges to the vertical oil storage tanks, API 650 closed top welded storage tanks standing outdoors. We must find some simple and effective methods to protect the API 650 closed top welded storage tanks in order to make them safely spend the summer. As a API 650 closed top welded storage tanks manufacturer, in order to reduce the direct sunlight rate of the vertical oil tank, reduce the temperature change of the oil tank, and reduce the evaporation loss of the oil tank, we usually adopt the measures of applying sunscreen paint and washing with warm water.
