For 2" MNPT Seal Housing
MID – Minimum Insertion Distance
D1 – Distance from the top of the valve to the pipe
WT – Pipe Wall Thickness
Ls – Pipe ID x 0.25 (Sampling Area Length)
Lt – Thread Engagement (0.75")
IAS Factor – 3.25"
MID=D1 + WT + Ls + IAS Factor - Lt
Example: D1=14"
WT=0.322"
ID=7.98"
IAS Factor=3.25
Lt=0.75"
MID=14 + 0.322 + (7.98 x 0.25) + 3.25 - 0.75
MID=14 + 0.322 + 1.995 + 3.25 - 0.75=18.817"
