Quality control of API standard 650 flat-bottom steel tanks

The application of API 650 is as stated by the American Petroleum Institute: The production and installation of our ground welded steel API standard 650 flat-bottom steel tanks storage tanks are generally used in industry; under normal circumstances, the storage tanks installed on the industrial site in the United States are in accordance with API 650, API 620 and API 12d Standards are established.

Welders participating in the construction of API standard 650 flat-bottom steel 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.

Low-pressure Storage Tanks Fireproofing
Although general fire prevention and fire protection measures are expected to be fully covered by other safety codes, tanks API standard 650 flat-bottom steel tanks constructed according to these rules, which may be subject to fire exposure resulting from any cause, shall have their supports suitably fireproofed.
Special consideration shall be given to provisions for ample drainage facilities for accidental spills or leakage of flammable contents from such tanks or adjacent piping and other equipment if the contents may become ignited.
Subject to special considerations in isolated locations, tanks in which flammable liquid products are stored at temperatures well above their average boiling point shall be suitably fireproofed or otherwise protected.

Customer service center has provided after-sales service for many large-scale information systems, and has accumulated rich working experience in the process of API standard 650 flat-bottom steel tanks service for many years. It can provide accurate, timely and high-quality support and service for users, which is well received by users.

Management information and high efficiency. Because of the rapid flow of API standard 650 flat-bottom steel tanks goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
