Product Description

API Cement Casing Pipe Centralizer for oilfield1) Material: Carbon Steel or 65Mn or Alumimium or Nylon2) Type:Bow Spring casing centralizer; Solid Rigid casing centralizer3) Standard:API 10D4) API and ISO certified5) Specifications:4 1/2”—20”. More special sizes or combination are available as requested.6) Photos:7) ApplicationCasing centralizers are to help center the casing in the wellbore, allowing even distribution of the cement around the casing during cementing operations.8) Function

a. Take casing to designed position by reducing sticking while casing going down.b. Centralize casing in well.c. Balance liquid pressure in annular space by reducing adhesion phenomenon.d. Improving replacing ratio of mud and boosting cementing quality by reducing channeling effect.e. Reset force of double-bow casing centralizer is higher than sigle-bow casing centralizer’s, and centralization performance is stronger.9) Features of Bow Spring Centralizers:

a. Designed for high restoring force and low starting&running forceb. Undergo special coating process to prevent from rustc. For hinged bow spring casing centralizers, end collars are designed with self-locking action, which are easy to assemble and can be shipped in half assembled condition for less shipping and storage costs.10) Features of Solid Rigid Centralizers

a. Hinged and slip-on versions available.b. Shock, impact and corrosion resistant.c. High tensile and yield strengths.d. Available with straight or spiral blades.e. Helps ensure positive centering in deviated or horizontal holes.f. Helps prevent differential sticking while running casing.11) Parameter of Bow Spring Casing Centralizer
