A131 grade A plates API 650 low-alloy steel tanks

API 650 external floating roof storage tanks are generally called external floating roof API 650 low-alloy steel tanks tanks, which means that the storage tanks are externally open tanks without a dome design, and are equipped with vertical floating roofs. API 650 external floating roof storage tanks are usually used for large More than 20,000 cubic meters of open steel API 650 low-alloy steel tanks storage tanks for storing volatile petroleum products such as crude oil, gasoline, kerosene, etc.

Determination of Required Capacity
The aggregate capacities required for any vent valves, pressure-relieving valves, and/or vacuum-relieving valves to be provided should be determined as follows:
a)For thermal breathing and product movement, the rules given in API 2000 shall be followed. The required capacity as the result of the product movement into the tank API 650 low-alloy steel tanks given in API 2000, shall be multiplied by the ratio of the absolute tank pressure to atmospheric pressure (14.7 lbf/in.2 absolute).
b)For supplemental safety pressure-relieving devices to take care of extra venting capacity required in case of external fire exposure, the rules in API 2000 shall be followed.

The API 650 low-alloy steel tanks must go through strict inspection before putting into use. Inspection of plate groove of API 650 low-alloy steel tanks, vertical oil tank: After finishing the groove processing of oil tank plate, it is necessary to conduct dye penetrant inspection on the groove. This process is mainly aimed at the hard damage of groove in the machining process and the defects of the plate itself. If any defect is found, it shall be processed again until the defect disappears.

Enterprise mission: to create value added steel products API 650 low-alloy steel tanks and provide first-class serviceWe are committed to quality. It is to firmly establish the concept that quality is the life of an enterprise, and make it clear that quality is the decisive factor for the survival and development of an enterprise. Adhere to the quality brand strategy and strive to improve the comprehensive competitiveness with quality as the core.Core values of the enterprise: innovation, dedication and transcendence. It is a highly refined spiritual quality to our staff.

The trend of international shipping development of large-scale ships and strategic joint ventures puts forward higher requirements for modern ports. Modern ports no longer use the general cargo throughput as a measure sign, and container throughput will become the main sign to measure the role and status of modern ports. The average container capacity in 2000 is 3200teu, and it is expected to be 5500teu in 2020.
