CENTERING OR INSULATING COLLARS

Centering collars are used to insulate a pipeline from a steel or concrete sleeve in road, path and/or railway crossings and they are fully compliant with the requirements de cathodic protection.

 We offer two types of collar assembly:

• Collar assembly by means of plastic pins.
• Collar assembly by means of screws and nuts.

Collars assembled by means of plastic pins require no tools or screws.

This assembly system allows a high load capacity.

The MF range includes six segment formats (Micro - Mini - Medi - Maxi and Maxi 0.5) and twenty-one rib heights that allow the centering of various pipeline diameters starting with ND 1-¼ in.
