If omitted, B1 and B2 are defaulted as follows:

Straight Pipe:

B1=0.5 B2=1.0

Curved Pipe:

B1=-0.1+0.4h; but not <0 or >0.5

B2=1.30/h2/3; but not <1.0; h=tR/rm2

Intersections:

B1=0.5

Butt-Welded Tees:

B2b=0.4(R/T)2/3 but not <1.0

B2r=0.5(R/T)2/3 but not <1.0

Branch Connections:

(r<0.5R)

B2b=0.50 C2b but not <1.0

B2r=0.75 C2r but not <1.0

C2b=3(R/T)2/3 (r/R)1/2 (t/T)(r/FTG ro) but not <1.5

C2r=1.15(r/t)1/4 but not <1.5

You can use the SIF(IN) and SIF(OUT) boxes to override the CAESAR II calculated values for any intersection. Override values only apply for the single element on which they are defined. SIFs can be calculated for partial intersections and dummy legs.

When IGE/TD/12 is active, the SIF/TEE dialog box changes its appearance to accommodate specialized SIF parameters. Refer to the supplementary IGE/TD/12 documentation for further information.
