It is single piece centralizer.
This kind of centralizer is with higher strength than traditional bow spring centralizers.
Our single piece centralizer performance is obviously better than any casing centralizers like bow spring centralizer and solid centralizer for casing running applications.
Our single piece centralizers have exceptional restoring force by pressional downhole tool lab,meeting API 10D bow spring centralizer test specification.
At the same time,our spring bow of single piece centralizer can bear pressure repeatly.We use two kinds of coating technology,one is powder coating,other is paint baking,thes two is completed by high temperature,it makes the centralizer have btter ability to risist corrison.
Our single piece centralizer sizes are available from 4-1/2in to 20inch,OEM manufacturing is accepted..
In order to cut down transportatiion cost,we usually put the smaller size centralizer into bigger ones.
Fuction of casing centralizer:
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.
