B16.34 Wall

[proinwv2]

Consider a valve body for inline flow simply described as three coaxial cylinders. An inlet, central body and an outlet. All round and the inlet/outlet of the same diameter. The Central body is a larger diameter.

My question is when determining the wall of the central body, do we not use 2/3 that diameter to establish a wall from table 3?

I ask this because the terminology in the standard only refers to "necks".

Thanks

Paragraph 6.1.1 has the general rules of wall section and does indicate that wall shall be no less than the values listed on Table 3A or 3B or calculated per Appendix VI (which yield essentially the same results).

so no you don't use 2/3 the values.

The 2/3 value that I refer to, is in para. 6.1.3 for sections beyond the [1.1(dtm)^.5]region.
