Abstract:
1. A tubular socket for connecting a fluid conduit to a container, comprising thermoplastic material, the tubular socket comprising: a first part comprising a thermoplastic material; a second part comprising a thermoplastic material, wherein the first part and the second part are connected to one another by a multi-component injection molding process; wherein the first part has a smaller creep tendency under pressure load than the second part and a smaller swellability relative to hydrocarbon-containing fluids than the second part; wherein the second part is configured to form a fusion-weld connection with the container; wherein the second part contains a reinforcement filler; wherein a quantity and a type of the reinforcement filler is selected such that a creep tendency of the second part approaches a creep tendency of the first part and a swellability of the second part approaches a swellability of the first part, wherein the reinforcement filler includes nano particles; wherein the strength of a connection between the second part and the container is at least as high as a strength of a connection between the first and second parts; and wherein a thermal shape stability of the second part is at least the same as a thermal shape stability of the container and at most approximately the same as a thermal shape stability of the first part, wherein the nano particles are nano clay or nano tubes.
