A131 grade EH36 plates API 650 mechanically-anchored steel tanks

In order to prevent the deformation of the bottom of metal vertical API 650 mechanically-anchored steel tanks during welding, comprehensive control measures such as strict control of assembly geometry size, reasonable welding procedure, process control of welding deformation and rigid fixation are adopted during assembly welding. The specific methods are as follows:
1. Strictly control welding groove forming of API 650 mechanically-anchored steel tanks.
2. Strictly control the size of tank welding seam assembly.
3. Define the welding sequence of tank bottom plate.
4. Reasonable distribution of welders.

The API 650 mechanically-anchored steel tanks outer wall shall be designed for the purging and operating pressure of the space between the inner and outer tank shells and for the loading from the insulation, the pressure of wind forces, and the roof loading.
The outer tank bottom, shell, and roof shall have a minimum nominal thickness of 3/16 in. (7.65 lbf/ft2) and shall conform to the material requirements of Q.2.3.

Selection of nominal diameter D of API 650 storage tank. In the design calculation of API 650 storage tank, the bottom plate thickness is the net plate thickness, that is, the actual thickness minus the corrosion allowance. In the design and calculation of API 650 mechanically-anchored steel tanks wall thickness in hydrostatic test, the thickness of bottom plate is the total thickness of steel plate.

The formula of enterprise success is: success = strategy × organizational capability, that is, having the right direction and strong organizational capability. The core competence of an enterprise depends on three pillars: first, talents (talent echelon); second, core values of enterprise culture; third, organizational governance model. If the enterprise is a tree, then the core values of talents, corporate culture and organizational governance mode are just like the root of the tree. With them, the enterprise will flourish and grow forever.
