The cost of anchoring a API Std 650 austenitic stainless steel storage tanks

Impact Test Requirements for Oil storage tanks Primary Components
All API Std 650 austenitic stainless steel storage tanks primary components of 9% or 5% nickel steel shall be impact tested in accordance with Q.2.2.2 through Q.2.2.4. Impact testing is not required for primary components of austenitic stainless steel, nickel alloy, and aluminum materials. Welds in high-alloy (austenitic) stainless steel shall be impact tested if required by Q.6.3.
Impact testing of plates, including structural members made of plate, shall comply with the following:a)Impact test specimens shall be taken transverse to the direction of final plate rolling. b)Charpy V-notch specimens shall be cooled to a temperature of –320°F for A353, A553, and A645 steels for impact testing.

API 650 petroleum storage tank has the advantage of long economic life: because there is no gas space on the liquid surface in the internal floating roof API Std 650 austenitic stainless steel storage tanks storage tank, the vibration generated during the transportation of liquid inside and outside the tank is reduced.

In order to prevent the deformation of the bottom of metal vertical storage tank, API Std 650 austenitic stainless steel storage tanks during welding, the number of welders should be reasonably distributed. When welding metal vertical API Std 650 austenitic stainless steel storage tanks, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.
