Description
Internal pipe blast tool type PBT-1
Application
- For pipes 3″ (75mm) – 12″ (300mm).
- Adjustable centering trolley.
- The use with standard blast device
Tool for piping cleaning PBT-1 is ideal for pipr cleaning from internal diameter 3 “(75 mm) to 12″ (300 mm). PBT-1 comprises of wolfram-carbide nozzle in Venturi pipe shape with round deflective tip from wolfram-carbide, which blasts abrasive agents in continual round. Materials from wolfram-carbide provide low wear and long service life. The centering sleeves and the trolley enable PBT-1 blast from internal pipe surfaces with internal diameter between 3″ (75 mm) and 12″ (300 mm). The centering sleeves enable PBT-1 use within scope 75 mm to 125 mm. The centering trolley enables setting PBT-1 to manage diameters between 5″ (125 mm) and 12” (300 mm).
Compressed air consumption | approx. 500 m3/hod (0,6 MPa) |
---|---|
Performance (axial shift speed) | approx. 1 m/min – after blast without trolley approx. 0,2 m/min – after blast with trolley with internal pipe diameter 300 mm |
Blast hose | DN 25 x 7 mm |
Internal pipe blast tool type PBT-2 ROTOBLAST
Application
- For pipes 12″ (304.8 mm) to 36″ (914.4 mm).
Extension PBT-2 ROTOBLAST is highly efficient mobile device for blasting from piping internal surfaces and it is propelled with standard abrasive device. Extension PBT-2 ROTOBLAST is suitable for the operation in flat pipes up to12 meters and diameter from 360 to 900 mm.
In order to operate PBT-2 ROTOBLAST, the nozzle series must be used CONTRACOR NTC (F), with diameter 6,5 – 9,5 mm. PBT-2 ROTOBLAST are connected to abrasive device instead of standard nozzles. The device requires compressed air with 7-8 bar pressure and lift volume defined in table below.
COMPRESSED AIR REQUIREMENTS

8 | 600 |
9,5 | 1000 |
Stands
Correct legs of required length compliant with the pipe diameter, to supports:
Pipe diameter, mm | Leg length, mm |
---|---|
360 až 500 | 230 |
500 až 700 | 350 |
700 až 900 | 400 |
