WHEN THE MAXIMUM ALLOWABLE CLEARANCE IS A VALUE BELOW THAT ACHIEVABLE BY A FIXED BLADE DESIGN, AN ADJUSTABLE MECHANISM IS REQUIRED TO REDUCE THE CLEARANCE AFTER INSTALLATION.
There are two main types of adjustable centralizers:
Shim type adjustable centralizer – Hinged designs which are constructed in two halves with two bolting flanges, containing two sets of adjustable blades per half. The blades on the design are adjustable and are kept to the required extension with the installation of nylon shims behind the blades. The adjustment is carried out by rope access personnel.
Remotely adjustable centralizer – In the same manner as shim type adjustable design, remotely adjustable centralizers are of a hinged design constructed from two halves with bolting flanges for easy installation around the casing. The blades are activated by a deployment ring which uses hydraulic cylinders to activate the adjusting mechanism. The adjustment is carried out remotely, enhancing operational safety.
