Sandblasters
Sandblasters can be used to achieve a very high degree of cleaning, especially for achieving a bare metal surface in steel and cast iron pipes. The equipment is pulled into the pipe to be cleaned and then slowly pulled back during sandblasting along with the air hose. These devices are available for the pipe sizes ranging from DN 60 (2.4 in) to DN 1,600 (64 in).
