Product Description
Hinged Welded Bow Spring Centralizer (Latch-type Centralizer) is designed to provide optimal standoff in the wellbore for efficient mud and cement displacement.
Our hinged welded bow spring centralizers (latch-type welded bow spring centralizers) are made of heat-treated spring steel bows, which can ensure maximum restoring forces and low starting forces. In addition, the hinged welded end design also makes the installation of stop collars or casing collars easy.
Hinged Welded Bow Spring Centralizer (Latch-type Centralizer) can be used in cased and open holes, vertical or horizontal wells and uderreamed and washed-out wells
Features of Hinged Welded Bow Spring Centralizer (Latch-type Centralizer)
· Low starting and running forces;
· Optimum restoring forces for most well requirement;
· Can minimize differential sticking;
· Can reduces casing drag;
