API standard 650 self-anchored tanks bottom-reinforcing plate
Heat-affected zone impact specimens shall be taken across the weld and as near the surface of the material as is practicable. The API standard 650 self-anchored tanks material specimens shall be of sufficient length to locate the notch in the heat-affected zone after etching. The notch shall be cut approximately normal to the material surface to include as much heat-affected zone material as possible in the resulting fracture. Impact test specimens shall be cooled to the temperature stated in Q.22.
Floating roof is the key component of floating roof API 650 storage tank, which can be divided into external floating roof and internal API standard 650 self-anchored tanks floating roof. The internal floating roof has a fixed top cover above the floating roof, which can prevent the floating roof from being exposed to wind and rain, and ensure the quality of oil stored under API 650 storage tank.
The Indian customer purchased our A516 Gr 70 pressure vessel steel plates to make tanks. They have very strict requirement for raw materials quality. For the A516 Gr 70 pressure vessel steel plates, they asked for Normalizing, 0℃ impact, A578 UT test, PWHT and so on tests, our Q/C department witness the production process with the technician from the customer company together. Meanwhile, we arrange BV inspection to check the quantity, spray mark, stamp on the A516 Gr 70 pressure vessel steel plates, and so on.
}Usually, the wind load in the API standard 650 self-anchored tanks construction area should be considered before the tank design and construction. The wind load in the API standard 650 self-anchored tanks construction area has an impact on the stability and economy of the API standard 650 self-anchored 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 standard 650 self-anchored tanks, the shape of the ladder, the platform, the pipeline and the top cover must be considered.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality API standard 650 self-anchored tanks products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
