Drill Pipe Centralizer

1. True Manufacturer 2. API Certified 3. Advantage Freight 4. Quick delivery time 5. Safe, Reliable and Efficient 1. Description The float collar is installed near the bottom of the casing string on which cement plugs land during the primary cementing operation. It typically consists of a short length of casing fitted with a check valve. This device may be a flapper-valve type, a spring-loaded ball valve or other type. 2. Characters: The welded ones have advantage such as: Integral structure, stable performance, simple and convenient to use, etc. The strong points of non-welded ones are: 1. It's finished well under mould pressing without any welding. 2. Starting and restoring force meets API 10D standards. 3. Easy and convenient to install. 4. Equipped with spinning disc to improve the displacement efficient. 3. Function: 1. Take casing to designed position by reducing sticking while casing going down. 2. Centralize casing in well. 3. Balance liquid pressure in annular space by reducing adhesion phenomenon. 4. Improving replacing ratio of mud and boosting cementing quality by reducing channeling effect. 5. Reset force of double-bow casing centralizer is higher than single-bow casing centralizer's, and centralization performance is stronger
