Nominal capacities of API standard 650 self-anchored flat-bottom steel tanks

This standard establishes minimum requirements for API 650 tank material, API standard 650 self-anchored flat-bottom steel tanks design, fabrication, erection, and inspection for ertical. aboveground，closed- and open-top.

For all API 620 crude oil tank other materials, the impact test temperature shall be at least 30°F colder than the design metal temperature. Alternately, materials impact tested at the design metal temperature or lower with Charpy impact test energy value of 25 ft-lb (average), 20 ft-lb (minimum) are acceptable for design metal temperatures above –40°F. API standard 650 self-anchored flat-bottom steel tanks materials with an energy value of 30 ft-lb (average), 25 ft-lb (minimum) are acceptable for design metal temperatures of –40°F or lower.

For the welding of API standard 650 self-anchored flat-bottom steel tanks bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the API standard 650 self-anchored flat-bottom steel tanks. The welding sequence of the central plate is from the center of the central plate to the surrounding.

Our company has a strong, professional R & D team and advanced and perfect sales service concept, which makes our API standard 650 self-anchored flat-bottom steel tanks products have a high visibility and market share at home and abroad. At the same time, we will always bear the principle of "credit first, customer first", always put the interests of customers first, and wholeheartedly provide each of our customers with the best products and services.
