API 650 stainless steel storage tanks impact testing of plates

Prefabricating API 650 stainless steel storage tanks components before construction can improve construction efficiency, save time and cost, and is currently a common method for the construction of large vertical storage tanks. The main prefabricated components of a large vertical API 650 stainless steel storage tanks include the tank body, the storage tank wall, the top of the storage tank, the bottom of the storage tank, and the accessories of the storage tank. The prefabrication of the components should follow a reasonable workflow, and carry out appropriate heat treatment and testing, so as to improve manufacturing accuracy.

Materials for API 650 stainless steel storage tanks primary components shall comply with the requirements of Tables R-1 and R-2. All primary components shall be impact tested in accordance with R.2.1.2 through R.2.1.4. Impact testing of API 620 welded storage tanks plates, including structural members made of plate, shall comply with Table R-1. Impact test specimens shall be taken transverse to the direction of final plate rolling.

Large net shell API 650 tanks or net shell of tank API 650 stainless steel storage tanks is a tank top for the surface grid structure and the physical structure form of truss structures, thin shell structure is reasonable, mainly for the top using triangle net shell, socket type net shell or meridian reticulated shell technology for the design of API 650 stainless steel storage tanks large-scale tank top, its great spanning capacity and uniform stress, good rigidity, less material, convenient assembly, safe and reliable.
