API Std 650 carbon steel tank lap joint

The API 650 is widely used for tanks designed to withstand low internal pressures, for the API Std 650 carbon steel tank storage of typical products such as crude oil, petrol, chemicals and water. We have extensive experience when it comes to API 650 tanks, varying from tanks built in the factory up to +/- 500m3, to tanks built on-location up to +/-15,000 m3.

The main advantages of the external floating roof API Std 650 carbon steel tank are large storage capacity, suitable for storing more than 10000 cubic meters of crude oil. Compared with the internal floating roof API Std 650 carbon steel tank, the production of external floating roof API Std 650 carbon steel tank is simple and the steel consumption is less. However, the central drainage system of external floating roof API Std 650 carbon steel tank should be installed on the outer floating roof to ensure that the accumulated water can be discharged smoothly in rainy and snowy days, and avoid sinking accident.

Allowable Design Stresses
The maximum allowable design stresses for the API Std 650 carbon steel tank 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.
