The capacity of API 650 ground supported tanks

This standard applies only to API 650 tank API 650 ground supported tanks whose entire bottom is uniformly supported and to API 650 tank in non-refrigerated service that have a maximum design temperature of 93°C (200 °F) or less.

API 650 ground supported tanks Manhole: The manhole is used for the operator to enter and exit the oil tank for inspection, cleaning and repair. For the convenience of personnel access, the installation position of the manhole is generally on the center line of the oil tank bottom, and the vertical oil tank is installed at the lowest layer of the tank wall. API 650 ground supported tanks Light-transmitting hole: Light-transmitting hole is also called day-lighting hole. It is used for lighting and ventilation when inspecting, repairing and scrubbing the oil tank. It is generally installed on the top of the oil tank above the inlet and outlet pipes.

The hardness of the welds contacting these environments, including the heat-affected zones, shall be considered. The weld metal and adjacent heat-affected zone often contain a zone of hardness that is well in excess of a value of 22 on the Rockwell C scale and could be expected to be more susceptible to cracking than would unwelded metal. Any hardness criteria shall be a matter of agreement between the Purchaser and the API 650 ground supported tanks manufacturer and shall be based on an evaluation of the expected hydrogen sulfide concentration in the product, the possibility of moisture being present on the inside metal surface, and the strength and hardness characteristics of base metal and weld metal.

In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API 650 ground supported tanks steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API 650 ground supported tanks steel transportation industry.
