A pipeline system in a linearly concentrating solar power station comprises at least one pipeline which is connected at one end to a converger and at a second end to a distributor. The converger and the distributor are arranged at a different geodetic height. When the converger lies on top pressurized gas can be fed into the converger and the distributor is connected to a drainage container. When the distributor lies on top pressurized gas can be fed into the distributor and the converger is connected to a drainage container. The drainage container is lower than the converter and the distributor.
