5154 aluminum bar API standard 650 larger diameter tanks

API 650 sets minimum requirements for the design, material, construction, and testing for aboveground, open and closed-top, cylindrical API standard 650 larger diameter tanks steel storage tanks in different capacities and sizes, roughly equating to the pressure of the atmosphere (not greater than the weight of the roof plates).

Inspection of API standard 650 larger diameter tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API standard 650 larger diameter tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API standard 650 larger diameter tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API standard 650 larger diameter tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.

Material for the outer tank API standard 650 larger diameter tanks and for the roof that contains the vaporized liquefied gas but is primarily subjected to atmospheric temperatures may conform to one of the following:
a)Table 4-1 for design metal temperatures down to –35°F (lowest 1-day mean ambient temperature of–35°F) without impact test unless they are required by Table 4-1 or by the Purchaser.
b)Table R-3 for design metal temperatures down to –60°F without impact tests unless they are required by Table R-4 or by the Purchaser.

For employees' development,  the company's transformation and development provides employees with a broad career development platform. The company needs "lion-type" entrepreneurial leaders who are full of entrepreneurial enthusiasm and dare to self-renovate. They also need a large number of professional and professional high-quality talents, and employees can get full capacity to display opportunities.

In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the API standard 650 larger diameter tanks steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
