Can the neck of a long-neck flange be used for reinforcement?
Thread Content
Can the neck of a long-neck flange be used for reinforcement? The standards specify a total height; can this total height be used for reinforcing the housing?
In addition to bearing pressure loads, the flange neck also takes on some of the flange torque; what is the appropriate thickness margin for it? I think it’s not possible to participate in the calculations for hole reinforcement
For long-neck flanges, the portion of the flange neck beyond the stress-affected zone functions as a nozzle, and this additional portion can be used to reinforce the shell.
See how the teachers answer and learn from it.
It is generally not used as a reinforcement insurance point.
The neck of a long-neck flange generally exceeds the effective reinforcement height of the pipe connection, and therefore cannot be taken into account in the calculations for hole reinforcement...
How is this extra portion defined?
In the opening reinforcement, there is the thickness required for the pipe connection; the remaining part is the excess.
:(I still don’t understand. A long-neck flange is a standard flange, and the thickness of its neck is determined with regard to the stress effects on the flange. Which thicknesses can be used for reinforcing the openings in the pipes?) It’s not specified in the flange standards?
