Design requirements for API 650 low-alloy steel tanks

API 650 is used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API 650 low-alloy steel tanks API 650 tanks with diameters between 8'-300', which are suitable for refineries, terminals, pipeline facilities and other projects.

Uplift on Foundation
For API Standard 620 tanks with an internal design pressure less than 1 lbf/in.2 gauge, the uplift shall be taken as the smaller of the maximum uplift values computed under the following conditions:
a)The internal design pressure times 1.5 plus the design wind load on the shell and roof.
b)The internal design pressure plus 0.25 lbf/in.2 gauge plus the design wind load on the shell and roof.

Corrosion of the API 650 low-alloy steel tanks body caused by external conditions such as high temperature, rain, humidity, or inadequate anti-corrosion measures of the oil storage tank itself, the water-bearing deposits in the oil storage tank caused corrosion and perforation of the inner surface of the oil storage tank bottom plate. Defects fatigue cracks caused by stress, with the accumulation of time, the compressive strength of the API 650 low-alloy steel tanks body decreases and corrosion cracks occur.

Our company has a strong, professional R & D team and advanced and perfect sales service concept, which makes our API 650 low-alloy 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.

Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, API 650 low-alloy steel tanks sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding.
