There is no issue with the supported bearing section head not allowing vertical load values
Thread Content
In the JB/T4712.4-2007 standard, why is the allowable vertical load [F] not specified for some oval end caps? For example: Suppose the allowable stress for the material S30408 used in standard elliptical end caps is [σ] = 130 MPa. For DN = 2800 mm and support number 6, the nominal thickness of the lower end cap is 8 mm. When performing calculations based on internal pressure, this nominal thickness meets the strength requirements (including reinforcement due to openings). With C = 1 mm, the effective thickness is 7 mm. Using interpolation methods, no allowable vertical load value can be determined for an end cap with a thickness of 6 mm. How should this be handled? Is it possible to only increase the thickness of the head by 10 mm? If so, I believe it might not be cost-effective for bulk equipment or storage tanks Is there a better way to calculate it or a better solution? Thank you!
The new standards differ greatly from the old ones. Has everyone taken a look? For example, regarding the load capacity of the support body: was it several units working together before, or is it now a single unit? Also, for the allowable vertical load on the rear end cap, after removing 4 mm, all the other values have become very large as well.
Which support is combined with several others? It seems to me that they are individual ones
It doesn’t seem to say how many together; it’s always just one at a time
