API ISO Casing Accessories Slip on Single Piece Centralizer
Single Piece Centralizer
Casing centralizers are used to help center the casing in wellbore, allowing even distribution of the cement around casing during cementing operations. Bow spring centralizer has high restoring capacity, which is determined by the shape and stiffness of its bows.
Slip On Single Piece Centralizer is a kind of casing accessories designed for deviated and horizontal holes. The centralizer provides high restoring forces while keeping starting and running forces at or near 0 lbf. This minimizes drag during casing running and maximizes standoff during cementing operations.
Application
Single Piece Centralizer is used in lean-profile drilling applications where centralizers are needed to pass through narrow / close tolerance sections, and then ultimately provide effective centralization of casing in under-reamed hole sections. Designed to meet and exceed today's most challenging well construction designs with proven performances.
Features
1) Made from high strength steel (65Mn steel) for whole piece.
2) Designed with slip-on structure.
3) Have better centralizing function because of its higher restoring force.
4) Undergo special coating process to prevent from rust
