Abstract
A condenser tube has a superhydrophobic surface. The superhydrophobic surface is produced on steam condenser tubes to achieve an improved runoff of condensation drops. These condenser tubes may be used in steam power generation. The surface of the condenser tube is textured so that the drops of condensation formed can run off well.

1-10. (canceled)
A condenser tube comprising:
- a tube body;
- and
- a surface coating provided on the tube body, a microtexture cooperating with the surface coating in such a way that drops formed by condensation run off the condenser tube.
A method for surface treating a condenser tube, comprising:
- applying a surface coating on a surface of a condenser tube body, the surface coating being formed from at least one water-repellent, hydrophobic, coating agent;
- and
- producing a texture on the surface of the condenser tube body.
A method for condensing steam in a power station, comprising:
- passing a coolant though through condenser tubes comprising:
- a tube body;
- and
- a surface coating provided on the tube body, a microtexture cooperating with the surface coating in such a way that drops formed by condensation run off the condenser tube;
- and
- passing post-turbine steam across an outside of the condenser tubes to condense the post-condenser steam.
