Downhole Slip-on Stamped Standoff Band Centralizer Factory Price
Slip-On Stand Off Band Centralizer
› The centralizer is made of stamped steel.
› It is designed for vertical well configurations where lateral loads are at a minimum.
› It is designed to provide a positive stand off the casing for both cased and open holes.
› The stand off centralizer is required where close tolerance between the casing and the hole is being encountered. › It allows for reciprocation and rotation during cementing and can be installed between set screw stop collar.
› Available in all sizes ranging from 4-1/2" to 20" and any special sizes or combinations are available on request.
Applications
The solid rigid centralizer ensure positive centering in deviated or horizontal holes. It can provide mechanism to centralize the casing in the wellbore and allow uniform cement flow around the casing by reducing the effects of channeling and protect the casing at all points.
But since the centralizers are smaller than the wellbore, they will not provide a good centralization as the bow spring centralizers do in vertical wells.
