How is the wall thickness of the nozzle determined during perforated reinforcement?
Thread Content
As the title suggests, I am working on my graduation project. It is a liquid chlorine storage tank, and openings need to be made for reinforcement at the manhole and safety valve connections. But the thickness of the joint cannot be determined! How is it calculated?
In the equipment manual, there is information on equal-area reinforcement, which allows one to determine the thickness of the pipe joint!
Firstly, when determining the wall thickness, corrosion margin must be taken into account. Section 6.3 of HG/T20581-2011 provides recommended values that can be used as a reference. GB17395 specifies the wall thickness series for pipes. The calculated thickness can be determined using the cylinder calculation formula in GB150. After selecting the wall thickness, perform the hole-strengthening calculations; if the results are satisfactory, it’s acceptable.
This must be an expert who often reads the specifications! ! !
