Abstract

The invention relates to a process for the production of hoses having a core of crosslinkable polyethylene, the hose being built up on a smooth metal mandrel, then bandaged with an outer winding and finally heat-treated in a vulcanisation vessel. In order to increase the temperature of use of the hoses, the hose built up on the mandrel is subjected to at least one additional heat treatment at about the vulcanisation temperature. The heat treatment advantageously takes place after the vulcanisation. The hose is cooled to ambient temperature between the heat treatments.
