In the protection of a portion of steam piping, e.g., live-steam piping, as it exits from the confinement chamber of a nuclear reactor, the portion of steam piping exits from the chamber in the direction of a mean radial plane of the passage through the chamber wall and is then bent substantially through 90 DEG . Upstream of the bend the piping includes a stopcock and between the stopcock and the bend the piping is held by guide elements between two sliding surfaces of guide means parallel to and symmetrical relative to the said radial plane, the guide means being supported on the confinement chamber wall, and by connecting rods symmetrical relative to the said radial plane and connected to the piping and the chamber wall.
