API standard 650 partially anchored liquid-storage tanks testing requirements

The company has been engaged in the design, construction and installation of foreign API 650 standard API standard 650 partially anchored liquid-storage tanks storage tanks for a long time. It has the international qualification of ASME welding technology, has the design ability of API 650 oil tanks and API 650 storage tanks, and has pressure vessel design and manufacturing license and GC pressure pipeline installation license. Certificate, API standard 650 partially anchored liquid-storage tanks petrochemical equipment pipeline general contracting qualification, safety production license, international trade import and export license.

The establishment of a correct method for evaluating the life of API standard 650 partially anchored liquid-storage tanks requires the preparation of criteria related to the strength and cracks of API standard 650 partially anchored liquid-storage tanks, mechanical damage mechanisms, corrosion mechanisms, and mathematical models of fatigue crack growth, etc., which are compiled into computer programs. In the process of programming the program, it is required to select the operating parameters, plates, reinforcement accessories, metal properties, corrosion levels, mechanical damage defects and other data of the oil storage tank under various conditions.

Insulation Load
For API 620 tanks designed and constructed with an outer tank containing loose fill insulation in the annular space between the tanks, the insulation weight shall be divided equally to the inner and outer tank wall for seismic lateral loads unless a more rigorous analysis is performed to determine the distribution. The insulation within the annular space shall not be used to calculate resistance to overturning. Insulation on the API standard 650 partially anchored liquid-storage tanks roof or suspended deck shall be applied to the tank supporting the load at the point or center of gravity of attachment and may be used to resist overturning.

Our company has sales department, technology department, quality inspection department, after-sales department, logistics department. Each department has professional knowledge and high professional quality, put customers first, think about the interests of customers, actively communicate with customers and solve problems smoothly.

The company's logistics uses third-party logistics. This logistics model plays an important role in improving the efficiency of our business operations. Third-party logistics is an important form of logistics specialization. As a company specializing in logistics, third-party logistics companies have a wealth of experts who specialize in logistics operations, which is conducive to ensuring the professional production of the company, reducing costs, and improving logistics level of the company. Both the customers and the company benefit from the logystics mode.
