Stationary siphon flows in arched magnetic flux tubes are studied. A pressure difference between the two footpoints of the tubes, which are anchored below the solar surface, drives the flow along the tubes. The radiative heat exchange between the tube and its surroundings is taken into account. In the upstream part of the arch the flow is accelerated and reaches a velocity maximum of a few km/s near the top of the arch. In the downstream part the flow is decelerated. The material flow is nearly adiabatic in the deeper and upper atmospheric layers whereas the flow behavior is isothermal near the solar surface. This leads to a strong temperature depression in the upper parts of the flux tube arch. The shape of the arch can be asymmetric and it can span several thousands of kilometers above the surface.
