600 Series – Slip-On, Welded, Close Tolerance Centralizer

The 610 Series Centralizer consists of two slip-on, three-inch-long notched steel collars with straight bow springs that are welded to the end collars. These centralizers are normally run between two stop collars or over a slip-on stop collar to provide the casing/liner a smooth bearing surface.

 

610 Series – Slip-On, Welded, Close Tolerance Centralizer with Set Screws

An upgraded version of the 610 Series, this centralizer features an end collar with evenly spaced integral set screws that allow the centralizer to be pulled into the hole; a stop collar is not required. It is recommended for use on casing grades of P-110 and lower.

640 Series – Slip-On, Welded, Extended Bow, Close Tolerance Centralizer

The 640 Series is a slip-on centralizer with straight extended bow springs welded to notched slip-on end collars. The extended profile ensures it does not hit the casing collars during casing running.

 

641 Series – Slip-On, Welded, Extended Bow, Close Tolerance Centralizer with Set Screws

In addition to straight extended bow springs, this centralizer features evenly spaced integral set screws that allow the centralizer to be pulled into the hole and eliminate the need for a stop collar. The 641 Series is recommended for use on casing grades of P-110 and lower.
