Optional design procedures of API standard 650 SUG II tanks
Fabricated to API standard 650 Welded Tanks for Oil Storage Shop Assembled API standard 650 SUG II tanks storage tanks, these tanks are commonly used at oil and natural gas terminals, API standard 650 SUG II tanks processing plants, and midstream facilities located along pipelines at the pumping, compression, or metering stations. API 650 storage tanks are designed and fabricated considering operating pressures up to 2.5 PSIG, corrosion allowance, wind loading, and seismicity.
Welders participating in the construction of API standard 650 SUG II tanks must pass the examination and perform welding within the validity period of the qualified items. Special operators such as on-site maintenance electricians, cranes, and shelf workers must hold job certificates. All oil pipelines need to use arc welding for bottoming and electric welding to ensure the welding quality. Oil tanks and process pipelines must be tested for non-destructive flaws in accordance with the flaw detection ratios and methods required by the design and acceptance specifications. The flaw detectors must be certified.
When as-rolled plate material complies with impact test requirements as specified here, the material need not be normalized. If, as with ASTM A516, the specification prohibits impact test without normalizing but otherwise permits as-rolled plates, the API 620 welded storage tanks material may be ordered in accordance with the above provision and identified as “MOD” for this API modification.
Our company attaches great importance to technical support and after-sales service, and has established a customer service center to provide unified technical support and service for API standard 650 SUG II tanks various engineering projects. Customer service center has a strong technical force of technical service team, composed of a customer service center manager, several API standard 650 SUG II tanks after-sales service personnel, responsible for unified acceptance and processing of local after-sales service needs.
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.
