ISO 630 grade E275 quality B plates API 650 flat-bottom tanks
The American standard API 650 design has been widely used. We can use our existing professional design knowledge to serve the construction projects of large API 650 flat-bottom tanks storage tanks, oil tanks and water tanks. The company is a small and medium enterprise that can provide American standard API 650 design software, design qualifications, and design capabilities.
The density of the liquid API 620 large welded, low pressure storage tanks stored shall be its maximum density within the range of design temperatures, but no less than 36 lbf/ft3. The maximum allowable tensile stress shall be taken from Table 5-1 or Table Q-3. For the maximum allowable stresses for design loading combined with wind or earthquake loads, see API Standard 620 5.5.6 for carbon steel and Q.3.3.5 for stainless steel and aluminum.
Oil storage tank with floating roof structure: The floating roof in the API 650 flat-bottom tanks oil storage tank can effectively reduce the volatilization consumption of oil, because the gas space on the oil liquid surface in the floating roof storage tank is small, the exhaust volume is low, and the breathing loss is very small. That can reduce the volatilization loss caused by the "big breath" of the API 650 flat-bottom tanks. Strengthen the inspection and maintenance of API 650 flat-bottom tanks: regularly check the sealing conditions of oil storage tanks, and check and maintain important auxiliary equipment to ensure good sealing performance.
Do a good job of thought introduction based on people. Human based management is the most important link in standardizing employee behavior management. In daily behavior management, we should establish the central position of human and play an important role of human. Employees are not only the builders and exercisers of corporate culture, but also the executors of code of conduct. The code of conduct should be finally implemented into the thoughts and actions of employees.
Steel logistics takes “steel” as the carrier, “logistics” as the operation, and “information” as the core. It integrates steel trade, e-commerce, and tripartite logistics as one. The flow of funds, information, and logistics promote each other and integrate with each other. Construction industry, metallurgy industry, information industry, modern logistics cross-industry. Our logistics service team will make sure our goods delivered to the leaving port on time.Makes you worry-free after sales.
After-sales service team is a key department to test the steel quality. Product quality is always the foundation of our survival and development. The company's full inspection from raw materials to finished products; and implements standardized, scientific, and strict internal quality control and management systems in accordance with the process flow during the production process; products can only leave the factory if qualified, and follow-up problem solving systems are implemented in after-sales services to guarantee the customers’ interest.
