摘要

The invention relates to a high-pressure pipe element comprising at least two metal tubes 1 and 3 reinforced by hoops 2 and 4, the ends of the tubes being made bare. The tubes are assembled end-to-end by welding 5 the bare ends together. A sleeve 6 covers the weld 5 and a portion of the hoop 2 and 4 of each tube, forming an annular space between the bare ends of the tubes and the sleeve, the space being filled with a curable material 9.
