CONTRACOR®PBT-2 Internal pipe blasting tool
1.2 General description
PBT-2 ROTOBLAST is a high-performance mobile device for abrasive blast cleaning of the
inner surfaces of pipes, and is powered by a standard abrasive blast machine.
1.3 Technical characteristics
PBT-2 ROTOBLAST is suited for operating in straight pipes up to 12m in length and with
diameters from 360 to 900 mm.
In order to operate the PBT-2 ROTOBLAST, CONTRACOR NTC(F)-series abrasive blast
nozzles with 6.5 – 9.5 mm diameter are required.
PBT-2 ROTOBLAST connects to the abrasive blast machine in place of a standard abrasive
blast nozzle.
The device requires compressed air with 7–8 bar pressure and the displacement volume
given in the table below. The abrasive-air mixture must be fed along a hose with a mini-
mum diameter of 1 ¼”. Using hoses with a smaller diameter will lead to quick wear and
reduced cleaning performance.
REQUIREMENTS FOR COMPRESSED AIR

LEGS
Fit legs of the required length, corresponding to the pipe diameter, into the supports.

2. Set-up of device
Set the PBT-2 ROTOBLAST device on a hard level surface.
Loosen the locking nut (28) and unscrew the rubberized pipe (35) by 5-10 mm.
Turn the rotating head (30) 5-6 resolutions by hand, which should rotate freely.
Fit the abrasive blast nozzles to the rotating head (30).
Tighten the rubberized pipe (35) by hand all the way.
Check rotation of the rotating head (30) by hand. The head should be turnable with one
hand, but with considerable effort.
Connect the compressed-air hose to the inlet CFT coupling.
Put on all sandblast operator personal protective wear and prepare for operation.
Holding the PBT-2 ROTOBLAST tightly, gently feed compressed air at the working volume
and pressure.
Check that there is no discharge of compressed air through the control ports of the bush-
ing (6). If there is leakage of compressed air, see point No.6.
Gently loosen the rubberized pipe (35) until the rotating head (30) starts to rotate by itself.
Try to rotate the head (30) within the range of 1-2 revolutions per second.
Repeat point 10.
Stop the feed of compressed air to the PBT-2 ROTOBLAST device.
Without moving the position of the rubberized pipe (35), tighten the locking nut (28).
Set the legs to the required length.
Connect the front and rear parts to the PBT-2 ROTOBLAST.
The device is ready for operation.

3. Performing abrasive blast cleaning
Place the PBT-2 ROTOBLAST device into the pipe.
Connect the PBT-2 ROTOBLAST to the abrasive blast machine.
Push the PBT-2 ROTOBLAST through to the opposite end of the pipe.
Turn on the abrasive blast machine.
Check the rotary speed of the head (30). Adjust if necessary.
Push the PBT-2 ROTOBLAST device by the abrasive blast hose through the pipe. Carry out
the procedure at a speed that ensures the necessary level of cleaning.
When the device exits the pipe, check that there is no discharge of compressed air or dust
through the control ports of the bushing (6). If there is leakage of compressed air or dust,
see point No.6.
4. Maintenance
ATTENTION!
The main system for slowing uncontrolled rotary acceleration of the rotating head with
abrasive-air nozzles is the brake housing (8) and the friction pad brake (32).
After each cleaning operation, it should be checked that there is no discharge of com-
pressed air or dust through the control ports of the bushing (6). If there is leakage of
compressed air or dust, see point No.6.
The PBT-2 ROTOBLAST device must not be used with a worn leather gasket (15).
Check for wear of the friction pad brake (32) after every twelve hours of operation.
Check the rotation of the leg wheels (38) every time. If rotation is jamming or locking,
remedy the problem or contact the service centre.
Remember that the rotating head (30) has direct contact with the working abrasive-air
mixture. Ensure that it is intact and replace with a new one if there are signs of wear.
If there is prolonged use of PBT-2 ROTOBLAST with a worn leather gasket, the rubber
spring (34) must be replaced.
If there is a worn groove (recess) in the carbide ring (33) which is more than 0.6 mm deep,
replace it with a new one.
In order to prevent increased wear of the abrasive blast nozzles, switch them around after
10 work cycles of the unit.

CONTRACOR®Version 6.0
If there is jamming when the rotating head (30) rotates, then check the condition of the
bearings (5) and replace them if they are defective.
Whenever the PBT-2 ROTOBLAST is serviced, the condition of the bearing gasket (25)
should be checked. If there is any wear and tear, replace it with a new one.
If all precautions and preventative measures have not helped to keep the bearings (5)
from failing, then replace them with new ones.
Leather gasket
ATTENTION!
The part of the equipment most susceptible to wear and in need of being checked is the
LEATHER GASKET (15). If the component is not replaced in a timely manner, there will be
inevitable high costs in repairing the equipment.
In order to change the leather gasket (15), loosen the locking nut (28) and unscrew the
rubberized pipe (35), unscrew the four screws (17) and disconnect the seal.
Replace the leather gasket.
Assemble in the reverse order.
5. Main defects and failures
Defect Reason
The head (30) doesn’t rotate or
rotates slowly.
The rubberized pipe (35) has been
overtightened. Loosen it.
Foreign particles are getting in the
bearings (5).
Replace the whole sealing element
and bearings (34, 33, 15, 25, 22
& 5).
Leakage of air or dust through the
control ports of the bushing (6). Wear of leather gasket (15). Replace.
The head (30) rotates
uncontrollably. The brake pad (32) is worn. Replace with new one.
Vibration. The abrasive blast nozzle has
clogged up. Clean the nozzle.
Overheating of unit.
Wear of leather gasket (15).
High rotary speed of head (30).
The brake pad (32) is worn.
Replace.
Reduce the rotary speed to the
recommended level.
Replace with new one.
