PIPE INTERNAL TREATMENT SYSTEMSThe sandblasting and shot blasting treatment of cylindrical bodies takes place automatically through the use of the devices described on the "INTERNAL PIPE TREATMENT DEVICES" page in the "SANDBLASTING MACHINES" section. Based on the diameter and length of the cylinder, and therefore based on the device to be used, the cylinder itself can remain fixed or rotate along the longitudinal axis. In this second case it is also possible to combine the internal treatment with the automatic sandblasting of the external surface.
