  Phagraphene (PhaG) is a quasi-planar 2D structure composed of $5-6-7$ ring
sequence. We have investigated the structural and mechanical properties of
phagraphene nanotubes (PhaNTs) through fully atomistic reactive molecular
dynamics (MD) simulations. For comparison purposes, the results were also
contrasted to similar carbon nanotubes (CNTs). Results showed that PhaNTs and
CNTs present similar brittle fracture mechanisms. The Young's modulus values
obtained for PhaNTs were smaller than the corresponding ones for CNTs. Both,
PhaNTs and CNTs, present equivalent fracture strains ranging between 15\%-20\%.
For the ultimate strength values, CNTs present values about 30\% higher than
the corresponding ones for PhaNTs.
