the following example is for you reference.


1.Brief Introduction:

  

 Single piece centralizer is suitable for vertical well, horizontal well and highly deviated wells. 
this kinds of centralizer is with higher strength than traditional bow spring centralizers,although we call it bow spring centralizer.
Ur single piece centralizers have exceptional restoring force by pressional downhole tool lab,meeting even exceed API 10D bow spring centralizer test specification.

Our single piece centralizer sizes are available from 4-1/2in to 20inch,any special sizes can meet your requirement according to casing and well hole size.

It is shipped in assembled condition only,when shipping them,in order to save space and shipment charges for customers,we usually put the smaller size centralizer into bigger size centralizer.
