INTRODUCTION
DESCRIPTION
The Rotoblast tool cleans the interior of pipes up to 40’ long and ranging in size from 8” (210 mm)
to 35” (890 mm) I.D. The tool connects to most abrasive blasting machines in place of a standard
nozzle. As the tool passes through the length of the pipe being cleaned, abrasive is ejected by two
special nozzles mounted on a rotating head. Optimal rotating speed is controlled by the braking
system. An adjustable centring carriage supports the tool through the pipe internal. The chart
below shows the recommended centring legs, nozzle sizes and compressor capacities for different
pipe diameters.
Failure to perform proper maintenance, particularly when dust seals are involved, will result
in severe damage to this tool. Read all the instructions carefully.
WARNING
SET-UP AND OPERATION
Equipment and materials required:
The system set-up for the Rotoblast operation is the same as for any other blast cleaning
operation, i.e. an air compressor, an optional moisture separator, a blast machine, a helmet air
supply system.
Consult the chart below to determine the proper carriage size.
Abrasive to be used for optimal operation is between 16 (1.2 mm) to 35 (0.5 mm) mesh size,
except for Aluminum Oxide and Silicon Carbide (sand). These two abrasives shorten the tool’s life
unacceptably.
Centering carriage:
The carriage fits to the Rotoblast as one assembly.
It’s consists of two collars, three two-wheel roller bars and four sets of centring legs
(6 legs p/set).
