Abstract
A connection, and methods of making an using such a connection, the connection comprising a first layer; a second layer concentrically disposed about the first layer; and a laser-induced seal between portions of the first and second layers; wherein the laser-induced seal provides a fluid-tight engagement between the first and second layers. As to particular embodiments of the connection, the first layer can be incorporated into a first conduit and the second layer can be incorporated into a second conduit.
Claims19
A connection comprising:
- a first conduit having opposing first conduit external and internal surfaces, said first conduit internal surface defining a first conduit passageway;
- a second conduit concentrically disposed about said first conduit, said second conduit having opposing second conduit external and internal surfaces, said second conduit internal surface defining a second conduit passageway;
- said first and second conduits formed from corresponding first and second materials selected from the group consisting of:
- a thermoplastic elastomer, polypropylene, polypropylene derivatives, polyethylene, polyethylene derivatives, polyolefin elastomer, polyvinylidene fluoride, polycarbonate, and acrylonitrile butadiene styrene;
- and
- a seal between said first and second conduits, said seal formed from fused first and second materials;
- wherein said seal provides a fluid-tight engagement between said first and second conduits;
- and
- wherein said seal forms a recess which inwardly extends from said second conduit external surface.
