Discussion on several issues in the calculation of conical heads
Thread Content
5.6.4.1/.2 Unflanged conical shells under internal pressure: It is necessary to determine whether reinforcement is required at the connections between the large and small ends. What is the difference between the reinforcement designs for the connections between unflanged conical shells and cylinders as described in 5.6.4.4? I’m a bit confused about the second enhancement; please advise
I took a look at the standards; sections 5.6.4.1/2 of those standards deal with the reinforced calculation of the end thicknesses of flangeless conical shells subjected to internal pressure. 5.6.4.4 deals with the reinforcement design at the junction between a flangeless conical head and the cylinder, under the combined action of internal pressure and axial load. And it has a scope of application; looking at the standards in detail will make it clear.
The first is to check the strength, and the second is to check the stability of the joints; you can take a look at the definition for standard 150.
