The article presents the results of extruding pipes with the dimensions of 45.04.0 and 108.0×4.0 mm, made from 0.08 C-0.18 Cr-0.1 Ni-Ti steel with the use of proposed glass lubricants in comparison with the use of the lubricants currently used in VTZ. The comparison was made for the viscosity of glass lubricants. A research was carried out for the influence of glass-lubricating materials on the power parameters of the pipe extrusion process. A metallographic research of the front and rear ends of finished pipes was carried out, a study for the thickness distribution of glass-lubricating materials after the pipe extrusion process was carried out, an X-ray spectral analysis of glass-lubricating materials was carried out. The article presents the results of the research of the surface of finishedsize pipes in laboratory conditions. Conclusions are made about the technological features of the application of the proposed glass lubricants.
