Product Description
Product Description
Positive bow centralizer is used for both casing and tubing applications that require concentric casing strings.
In deviated cased holes, the centralizer significantly reduces frictional drag and can provide nearly 100% standoff.
Rib design allows for optimized fluid flow in the annulus, which contributes to a high-quality primary cement job.
