ISO 630 grade E275 quality B plates API standard 650 floating-roof tanks

We can process the steel materials according to your drawing. Or if you can not make drawing, please send us API standard 650 floating-roof tanks specific data and requirements, our technical department can make design and drawing for you, and then confirm with your technician or engineer. If all is OK, our processing center will process the steel materials according to the drawing. So no matter what size and shapes you need, we can meet demands at the most time.Investigation of Subgrade
On actual steel storage tank sites to be used, test borings or test pits, or both, may be made at the direction of a competent engineer who will specify the number and location. They need not be equally spaced but should be laid out to uncover possible weak spots.
In general, test loadings of subgrade at the bottom of test pits need be resorted to only when such heavy loading as may be imposed by footings for major column supports for spheres or similarly elevated API 620 low-pressure tanks is specified. Results may be deceptive if average load-bearing capacity over a considerable area is wanted. All field data shall be recorded with maps, and copies shall be supplied to all engineers concerned with design, erection, and later operation.The inner layer of API 650 tank is the same as that of single layer tank. It is made of high-quality steel plate in strict accordance with the standard of "steel welded atmospheric pressure vessel". The thickness of API standard 650 floating-roof tanks steel plate reaches the standard and the service life is longer.Since its inception, the company has always adhered to the development policy of "survival with quality, development with products, cooperation with credibility, and service with customers". I would like to express my heartfelt thanks to the old and new friends and customers who have always given care, support and help to the company! And sincerely hope to establish a long-term cooperative relationship with them, mutual benefit and common development.The preparatory work before the construction of the API standard 650 floating-roof tanks is directly related to the quality assurance, project progress, construction safety and other aspects of the entire oil tank project. Therefore, the preparation work before the API standard 650 floating-roof tanks construction should be paid attention to and planned. Before API standard 650 floating-roof tanks construction, you need to prepare conventional machinery, materials, and facilities, as well as the quality control of the project, such as the installation method of the API standard 650 floating-roof tanks, the welding method of the steel plate, and the inspection of the tank material. In addition, there is the most important item, construction safety protection.
