API Std 650 floating-roof tanks welding operator

Selection of nominal diameter D of API 650 storage tank. In the design calculation of API 650 storage tank, the bottom plate thickness is the net plate thickness, that is, the actual thickness minus the corrosion allowance. In the design and calculation of API Std 650 floating-roof tanks wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.

Usually, the wind load in the API Std 650 floating-roof tanks construction area should be considered before the tank design and construction. The wind load in the API Std 650 floating-roof tanks construction area has an impact on the stability and economy of the API Std 650 floating-roof tanks. In the area with large wind load, it is safe to design the tank as "squat". When calculating the wind force, the influence of the thickness of the insulation layer of the API Std 650 floating-roof tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.

Every after-sales service shall have a detailed record of the customer's product problems and handling methods. The records shall be sorted into volumes and filed on a monthly basis, and submitted to the technical department for filing. The problems found in the after-sales service shall be summarized in a timely manner, discussed with the technical department, the quality inspection department and the production department, and a proper solution shall be proposed for the technical department to improve in a timely manner;
