The experimental transverse momentum (pT) spectra of the strange hadrons (
, 
,
, 
and 
) in inelastic pp collisions at = 7 TeV, measured at midrapidity range 
by the ALICE collaboration, are analyzed. The EPOS-LHC model calculations reproduce quite well the ALICE experimental transverse momentum distributions of all studied strange hadrons in inelastic pp collisions at 
= 7 TeV in pT region up to 5 GeV/c. The EPOS-1.99 model calculations underestimate systematically the ALICE experimental pT spectra of all studied strange hadrons, except that of , in these pp collisions. Quite good description by the EPOS-LHC model of the experimental pT spectra of all studied strange hadrons in pT region up to 5 GeV/c could be attributed to the consistent treatment of the cross sections and the particle production in the framework of the EPOS-LHC model. The average pT of the particles from the ALICE experiment as well as EPOS-LHC + EPOS-1.99 calculations increase linearly with increasing particle mass in inelastic pp collisions at = 7 TeV. This is likely due to the significant collective radial flow of the particles developed in inelastic pp collisions at = 7 TeV. Both EPOS-LHC and EPOS-1.99 models describe quite well the mass dependencies of the experimental mean pT of the various particles in inelastic pp collisions at = 7 TeV. The experimental and EPOS-LHC + EPOS-1.99 model data on 
versus mass dependencies of the various particles, produced in inelastic pp collisions at = 7 TeV, are fitted very well by a linear function with the single slope parameter. These results suggest that the collective radial flow calculations are quite adequate and very satisfactory in both EPOS-LHC and EPOS-1.99 models.
