Specifies Tc, the crotch thickness measured at the center of the crotch. Applies to welding tees, extruded tees, and sweepolets. For B31J, see Intersection Types to match B31J and CAESAR II tee types.
Default Values
-
When no value is defined, the software uses zero.
-
When no value is defined for B31J, the software uses 1.1*(run pipe thickness). B31J recommends a value up to 1.5*(run pipe thickness).
-
This property does not display for FRP piping codes.
-
When welding tee and welded-in contour insert tee (sweepolet) geometries meet the B31J dimensional requirements of a smooth crotch radius and an increased crotch thickness, flexibility factors and SIFs can be reduced. See Reduction of SIFs and Flexibility Factors in B31J Methods.
