SW6 only calculates the excess area of the protruding part of the Takeover – what’s the problem?
Thread Content
When reviewing the calculation sheet, there is a nozzle on the cylinder whose outer extension exceeds 120 mm, while its inner extension reaches 150 mm from the bottom of the tank. It was found that SW6 only took into account the excess metal area of the outer extension part of the nozzle – what is the issue here?
After checking 150, since the wall thickness of the inward-extending portion needs to take into account the corrosion margins on both sides, the area available for reinforcement in this case is negative; therefore, only the excess area of the outward-extending portion was taken into consideration.
Corrosion allowance: 4; tube wall thickness: 8. Double-sided corrosion on the extended tube – once the corrosion is complete, what excess area is left?
Double-sided corrosion margin; the wall thickness involved in reinforcement is 0
