RIVETS FOR CURVED APPLICATIONS

The problem our R&D Dept. had to face had multiple facets: first of all, how can a blind rivet fasten a curved application such as a tube, in which there is no complete adhesion to the inside?

Furthermore, as the application is in refrigeration and heating plants, the blind rivets are subjected to constant atmospheric variations, as well as to the passage of liquids.

Once again, structural rivets and their higher mechanical performance come in handy: higher shear, tensile and vibration resistance; hermetic sealing to liquids; resistance to humidity and corrosion; and last but not least, the structural action of the mandrel too, which remains blocked inside the rivet body once the blind rivet is applied.

Our team has developed a customized version of a Saribolt which, in addition to all the characteristics already listed, has ad hoc high grip range, and covers large holes or even slotted or not in axis with each other.

In addition, the head of the mandrel has a particular structure to ensure adhesion inside the pipes, which is fundamental because of the rounded shape.

Thanks to the know-how of our team and the possibility of managing the creation of the blind rivet from project to final assembly, we could customize the mechanical characteristics of one of our standard products, to find the right application for our customer.

The blind rivet obtained fully meets the needs, which gives us even greater satisfaction if we think of the initial difficulties that the application presented.
