API 650 stainless steel storage tanks emergency roof drains

In order to prevent the deformation of the bottom of metal vertical API 650 stainless steel storage 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 stainless steel storage 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 density of the liquid API 620 large welded, low pressure storage tanks stored shall be its maximum density within the range of design temperatures, but no less than 36 lbf/ft3. The maximum allowable tensile stress shall be taken from Table 5-1 or Table Q-3. For the maximum allowable stresses for design loading combined with wind or earthquake loads, see API Standard 620 5.5.6 for carbon steel and Q.3.3.5 for stainless steel and aluminum.

API 650 is widely used for tanks that are designed to internal pressures of 2.5 PSI or less and store products such as crude oil, gasoline, chemicals and API 650 stainless steel storage tanks produced water. Advance Tank has extensive experience with API 650 tanks ranging in diameter from 8' - 300' for refineries, terminals, pipeline facilities and other clients.
