<p>As protection against erosion of condenser tubes (3), there is proposed a device (8) which includes a shell which is intended to cover that part of the condenser tube which is exposed or subjected to erosion damage, and fastener devices which can be included in the shell. The device is intended to embrace the condenser tube with a centre angle (v) between 180° and 300°, preferably between 200° and 220°. According to a preferred embodiment, the device is comprised of a cut, resilient sleeve whose inner diameter is smaller than the outer diameter of the condenser tube. The sleeve is fitted to the condenser tube, by snapping the sleeve over the tube from one side thereof.</p> |
