Seismic design for API 650 SUG III tanks

API 650 storage tank stipulates that if the thickness of the lower wall panel obtained by calculating the anti-overturning moment is greater than the thickness of the API 650 SUG III tanks hydrostatic pressure test (both do not include the corrosion allowance).

Preheating should be performed by heating and maintaining this heat in appreciable lengths of the joint to be welded, preferably using a strip burner with a mild flame rather than a harsh flame such as that from a cutting torch. Electrical strip heaters are available and have been found to be satisfactory. The preheat of 300°F should be checked with a temperature-sensitive crayon, or similarly accurate means, so that the steel 4 in. (or four times the API 650 SUG III tanks plate thickness, whichever is greater) on each side of the joint will be maintained at the minimum preheat temperature. Ring burners or heaters are recommended for nozzle and manway welds. At no time during the welding should the base metal fall below a temperature of 300°F.

API 650 SUG III tanks, Vertical oil storage tank is an important equipment for many enterprises to carry out production, which provides important support and help for the storage of many reagents. Vertical storage tank is generally used as atmospheric pressure vessel. Advantages: the filling rate of cylindrical structure is second to that of spherical tank, and the largest volume of the storage tank can be made into tens of thousands of cubic meters. The structure is simple and the construction requirements are relatively low.

Team concept: respect, communication, coordination and symbiosisBusiness philosophy: leading by strategy, driving by innovation, creating valueManagement concept: goal oriented, efficient operation, stimulation of vitality and continuous improvementQuality concept: standard guidance, control process, craftsman spirit, leading serviceTalent concept: lifelong learning, give full scope to the talents, the sea refuses no riverInnovation concept: innovation is the first driving force for the company's high-quality developmentCustomer concept: taking customers as the center is the foundation of the company's survival and development

BBN company is a modern enterprise integrating steel producing, warehousing and logistics, processing and distribution. We are committed to creating a "one-stop steel procurement service" platform. The main products are I-beam, angle steel, API 650 SUG III tanks , H-beam, hot-rolled coil, welded pipe, spiral pipe seamless pipe and many other steel products. Standing stocks amount to more than 30,000 tons, and complete specifications, the company gradually moves towards large-scale distribution enterprises with serialized products, standardized services and modern transportation management.

The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
