API standard 650 self anchored flatbottom tanks terms and definitions

The API 650 is widely used for tanks designed to withstand low internal pressures, for the API standard 650 self anchored flatbottom tanks storage of typical products such as crude oil, petrol, chemicals and water. We have extensive experience when it comes to API 650 tanks, varying from tanks built in the factory up to +/- 500m3, to tanks built on-location up to +/-15,000 m3.

Aftershock Level Earthquake (ALE)
This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.
If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API standard 650 self anchored flatbottom tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.

Ultrasonic testing can find the internal defects of API standard 650 self anchored flatbottom tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API standard 650 self anchored flatbottom tanks and so on metal oil tanks. The feature of this method is convenient and fast.

Company through its own API standard 650 self anchored flatbottom tanks website, multimedia, radio, newspapers, the group, the handbook of the corporate culture carrier, approved and publicity column, in-depth to carry out enterprise culture construction, also through photography, painting, calligraphy, cartoon, speech, and the songs of the enterprise design, various cultural and sports activities to carry out enterprise culture construction.

As steel transportation belongs to the transportation of major parts, so in the process of transportation, modern logistics technology, such as centralized transportation, information technology, is a bit out of place. Based on the current situation of China's API standard 650 self anchored flatbottom tanks steel transportation industry, highway transportation is a way of transportation that many enterprises often choose. Naturally, its business volume also accounts for more than 50% of the whole API standard 650 self anchored flatbottom tanks steel transportation industry.
