Simplified design requirements for API 650 closed top welded storage tanks
Compared with the fixed roof API 650 oil storage tank without API 650 closed top welded storage tanks floating roof, there is no evaporation space. In principle, this eliminates the so-called "large breathing loss". Evaporation not only causes the loss of product quantity, but also affects the quality of API 650 closed top welded storage tanks product and pollutes the environment.
Inspection of Welded Storage Tanks Surfaces Exposed during FabricationThe edges of API 650 closed top welded storage tanks plates, openings and fittings exposed during fabrication shall be inspected carefully to make sure that any defects have been uncovered, as well as to determine that the work has been performed properly.Minor defects found may be repaired only after the inspector approves the method and extent of repairs. Materials that have more than minor defects that cannot be satisfactorily repaired shall be rejected.Spot radiographic or ultrasonic examination shall be not less than 6 in. extending along the weld. Spot radiography shall comply with the standards given in 7.15.1.3. Where spot radiographic or ultrasonic examination is applied at joint intersections, the surface shall be prepared and examined for a distance of 3 in. on each side of the intersection, making the minimum length of examination 6 in. on the horizontal weld and 3 in. on the vertical weld.
Usually, the wind load in the API 650 closed top welded storage tanks construction area should be considered before the tank design and construction. The wind load in the API 650 closed top welded storage tanks construction area has an impact on the stability and economy of the API 650 closed top welded storage 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 650 closed top welded storage tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.

In the process of API 650 closed top welded storage tanks steel transportation, enterprises often use railway transportation, highway transportation, water transportation and other ways to transport. According to the cargo owner's requirements on the timeliness of the goods and the different transportation routes, our company will choose API 650 closed top welded storage tanks different modes of transportation. According to the specific needs of customers, or specify the mode of transportation.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
