1060 aluminum tube API Std 650 ground supported tanks
API 650 petroleum storage tank stipulates that if the thickness of the lower siding obtained by calculating the anti-overturning moment is greater than the thickness of the API Std 650 ground supported tanks hydrostatic pressure test (both do not include the corrosion margin), the calculated thickness of the above siding required by the hydrostatic pressure is It should also be increased by the same proportion, unless special analysis is performed to determine the seismic overturning moment and corresponding stress at the bottom of each layer of API 650 petroleum storage tank wall.
Temporary Openings after Hydrostatic TestWhen approved by the Purchaser in writing, and only in the case of tanks which when complete have no shell penetrations, it is permitted to restore by welding up to four temporary shell openings after the hydrostatic test in accordance with the provisions of this section. Each temporary opening shall be restored by the insertion of a shell plate that matches the thickness and specification of adjacent shell material, and is welded into place with full fusion butt-welds. The API Std 650 ground supported tanks insert plate shall be round with diameter no less than 24 in. and no greater than 42 in.
Generally speaking, the duration of the "exhalation" of the API Std 650 ground supported tanks is longer than that of the "inhalation" of the API Std 650 ground supported tanks every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the API Std 650 ground supported tanks location, open area of the API Std 650 ground supported tanks, atmospheric pressure, filling degree of API Std 650 ground supported tanks, etc. When the API Std 650 ground supported tanks is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.
Our vasion is to create a first-class steel plate manufacturing enterprise with international competitiveness. Business Vision: Improve value with quality and become the leader in the industry. Core values: people-oriented, integrity, responsibility, excellence. Development strategy: Seek development through science and technology, and seek benefits from management.
