Beschreibung
Zusammenfassung:This pipe comprises a base body (16) forming a shaft (22), the shaft having an internal shaft surface (24), an external shaft surface (26), a first axial end (28) and a second axial end (30). The pipe comprises a cement mortar coating (80) disposed on the internal shaft surface, a first annular barrier (84) disposed at the first axial end of the shaft and adapted to oppose an axial flow of the cement mortar in the non-solid state, and a joint end (12), the joint end being defined by a joint part (40) of the base body that comprises an internal joint surface (42). The pipe comprises a joint coating (60) extending over the internal joint surface. The joint coating (60) is connected to the first barrier.
