The device is used to position the lance nozzle in the heat exchanger bundle tube and to prevent accidental retraction.
The device is clamped to the tube bundle flange. Swivel joints and a telescopic arm enable the lance within the protective sleeve to be positioned at each individual tube of the bundle.
When the operator retracts the lance a suitable sized stop within the protective sleeve prevents jetting to atmosphere.
For bundle diameters to 2 m & for lance i/d‘s 4, 6 and 8 mm.
Flange thickness max 140 mm.
