Product Description

7" API Oilfield Zinc Alloy Casing Centralizer

Spiral Solid Centralizers were developed in response to the need for better cementing in deviated and horizontal wells. The unique design ensures optimal flow area and is strong and resistant to impact, These Centralizers are also able to withstand high well bore temperature while providing maximum horizontal standoff.

Features

The fins or blades overlap the entire 360-degree open hole circumference
Reduced flow area between the spirals provides and creates a vortex motion that increases fluid velocity.
The extra length of the fins gives maximum centralization,high standoff,increases annular turbulence while the angle further enhances turbulence
Removal of debris from around the casing.
