Mechanical loads on API Std 650 mixed material tanks
The welded API 650 tank in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure API Std 650 mixed material tanks is permitted when additional requirements are met.
Impact Requirements for Controlled-rolled or Thermo-mechanical Control Process (TMCP) Plates: Subject to the approval of the Purchaser, controlled-rolled or TMCP plates (material produced by a mechanical- thermal rolling process designed to enhance the notch toughness) may be used where normalized plates are required. API 620 welded storage tanks each used plate, as rolled, shall be Charpy V-notch tested to the requirements of R.2.1.2.
Requirements for prefabrication of the top of large vertical API Std 650 mixed material tanks: The prefabrication of the tank top shall be prefabricated in blocks according to the drawings. Pay attention to the spacing of the welds after installation when setting out the material. Reinforcing ribs should be formed and inspected with an arc-shaped template. When a single top plate needs to be spliced, butt joints should be used. The forming of a single top plate should be welded between the reinforcing ribs and the top plate on the mould. After forming, check with an arc-shaped sample plate, and the gap should not be greater than 10 mm.
Group consciousness is an important psychological factor for the formation of enterprise internal cohesion. The formation of API Std 650 mixed material tanks enterprise group consciousness makes every employee of the enterprise regard their work and behavior as an integral part of the realization of enterprise goals, make them feel proud of themselves as a member of the enterprise, have a sense of honor for the achievements of the enterprise, and thus regard the API Std 650 mixed material tanks enterprise as the community and belonging of their own interests.
