Specifies the thickness of the fitting in the crotch.
Typical units (depending on your unit system):
-
in
-
mm
-
cm
As of the 2001 addendum, B31.3 uses this value to determine if the fitting meets the geometric criteria of B16.9 (see Note 8 in Appendix D of B31.3 for details). If this value and the Intersection Crotch Radius are defined, CAESAR II applies Note 8 to determine how the flexibility characteristic is to be computed. If these values are left blank, the software uses the setting in the configuration file to determine how the flexibility characteristic is to be computed.
