The new 3+ Backing Ring

In pipeline engineering, the flanged connection is the most commonly used type of connection for non-permanent coupling of pipelines, or plant sections using screws or bolts. The flange allows a rigid connection between the pipes, ensuring maximum anti-slip safety.

Aliaxis has designed the innovative 3+ Backing Ring which, thanks to its optimized design, combines a unique lightness with exceptional mechanical strength.

The new profile has been scrupulously designed to have a thicker metal core at the points of greatest mechanical stress.

In addition, the pins inserted into the holes and the guided bolts tightening sequence make installation simple, safe and reliable.

The 3 PLUSES in detail of the new 3+ Backing Rings:

1. LIGHTNESS: Lightweight product and best in class performances due to the patented wedge shape profile of the metal core and the PP-GR coating ensuring chemical and corrosion resistance.

2. MECHANICAL RESISTANCE: Optimized and enhanced thanks to its new design that allows an excellent breaking load, outstanding elasticity properties and durability over time.

3. EASE OF INSTALLATION: Thanks to the bolts tightening sequence indications and to its symmetry that allows bi-directional installation.
