The tubes are essential components of the accelerator. Their function is to transport and accelerate a very intense proton or deuteron beam through the machine, from the ion source to the neutron production target, without significant losses. In this contribution we discuss the materials selected for the tube construction, the procedures used for their assembly and the testing performed to meet the stringent requirements to which it is subjected. The tubes have to withstand non-negligible mechanical stresses, they have to be completely tight since they separate the ambient air from the high vacuum (less than 10-6 Torr) through which the beam is transported and the materials from which they are made of have to be appropriate for this high vacuum. In addition the tubes have to withstand the high electric fields necessary to focus and accelerate the beam.
