A pipe connection is provided which comprises two pipe ends, one inserted inside of the other, and one consisting essentially of crosslinked polymer material, whereas the other consists essentially of crosslinked or non-crosslinked polymer material, the connection having a layer of polymer material press-fitted and crosslinked between the two pipe ends. The pipe fitting is made by arranging the two pope ends so that one is inserted in the other, one of the ends having a mechanical memory and having been deformed so that one of the pipe ends fits into the other, providing an in situ heatcrosslinkable polymer layer between the two pipe ends and heating the thus assembled pipe ends to crosslink the heat-crosslinkable layer, while the deformed pipe end returns towards its original shape, thus press-fitting the crosslinking polymer layer between the two pipe ends and making a strong, fluid-tight joint. |
