bending capacity of clamp connector

bending capacity of clamp connector

bending capacity of clamp connector

(OP)

I got API research report "bending moment capacity calculations for special API clamp / hub combinations" from the following link:

http://global.ihs.com/doc_detail.cfm?currency_code...=

unfortunately, it has not governing equations for determination of bending capacity and it seems that they should be extracted from fortran program which is not presented in the report.

can anybody help me to find governing equations of bending capacity of clamp connectors?

Kellogg method or pressure equivalent method even with correction factor (kove's factor)doesn't make sense for maximum bending capacity calculation of clamp connectors.

appreciate for any kind of help

RE: bending capacity of clamp connector

I suggest you to contact the supplier of the clamp connection. They must have tables that show acceptable bending moment, axial forces in addition to the internal pressure. Some cases they even have a software to do this analysis for you.

RE: bending capacity of clamp connector

The usual method for designing clamp hubs from scratch is ASME VIII Div 1, Appendix 24. In common with Appendix 2 this does not address external loads, so equivalent pressure added to internal equation is the normal route for analysis.

AS Saplanti correctly says, most vendors have tabulated external load limits. These are particularly useful since torsional moment is a contentious issue in a clamp.
