The installation distance of the casing centralizer should meet the requirements of the construction design. The selected outer diameter of the centralizer should be determined according to the wellbore.

Placement method:

1. Can be directly put on the sleeve.

2. It can be installed to move freely between casing coupling and coupling.

3. Can be installed in any part of the casing with a retaining ring.

When installing, the centralizer is buckled on the casing. After the hoop, the two pins are inserted into the upper and lower pins, and the locking pin is flattened or the pin is bent to prevent the pin from exiting and being checked into the well after being checked.
