1. plural of centralizer; devices, mechanisms, or tools used to center or align something in the middle of a space or structure
Usage: commonly used in technical and industrial contexts
2. in mathematics and abstract algebra, elements or subsets that commute with a given element or set
Usage: technical term used in group theory and ring theory
3. in oil drilling, tools inserted into a wellbore to keep the casing centered and prevent contact with the borehole wall
Usage: petroleum industry term

Examples

• The drilling crew installed centralizers at regular intervals to maintain proper casing alignment.
• Mechanical centralizers help reduce friction and improve cement bonding in the wellbore.
• In group theory, the centralizers of an element form an important subgroup.
• The engineer selected spring-type centralizers for the deep well application.
• Proper use of centralizers extends the life of the casing and improves well integrity.
