API 650 mixed material tanks shell design
The welded steel API 650 storage tank API 650 mixed material tanks is designed, manufactured and installed on the surface according to the API standard system classification. API 650, API620 and API 12D belong to the API standards for professional construction.
Prefabrication requirements of API 650 mixed material tanks, large vertical storage tank wall panels:1. The prefabrication of wall panel shall be processed in strict accordance with the requirements of the drawings, and inspection records shall be made.2. After the wall panel is rolled, it should be placed on the platform for inspection with a template. In the vertical direction, use a straight-line template to check, the gap should not be greater than 2 mm, and in the horizontal direction, use an arc-shaped template to check, and the interval should not be greater than 4 mm.3. When wall panels are rounded, attention should be paid to prevent irreversible plastic deformation caused by external forces. After rolling, it should be placed on the platform for inspection, and then placed on the prepared mold.
The increased uplift described in API Standard 620 tank Appendix Q is intended to apply to the size of the ringwall and foundation but not the anchorage. For tanks with an internal design pressure of 1 lbf/in.2 gauge and over, the uplift, if any, shall be calculated under the combined conditions of 1.25 times the internal design condition plus the design wind load on the API 650 mixed material tanks shell and roof.
