Shannon,
Pretty sure Cactus means 5" Diameter, XX Strong wall thickness (19.05 mm)
You need to look at what diameter your casings are and what wall thickness.
Also is it ASME IX or API 1104 you are using ?
If it is ASME IX, 2" Sch 40 will give you all diameters but only 7.8 mm wall thickness based on 2 x "T" of 3.91 mm.
If that is sufficient good, otherwise look at 2" Sch 80 (qualified to 11 mm) or 2" XX (qualified to 22 mm)
Hope that helps,
Regards,
Shane
