(borehole) CENTRALIZER, 4", 113.8mm, bore 160mm
Form
4" casing centralizers consisting of several strips shaped like a bow.
Fit
To be installed around 113.8 mm outer diameter casing and 160mm diameter boreholes.
Function
Tools to position the casing uniformly inside the wellbore to offer a more uniform distribution of cement and gravel pack around the casing. They also reduce the friction between casing and well bore and keep the casing from hitting the wellbore walls.
