For the production of insulation pipes, UNION can provide different solution to the customers. Single screw extruders (generally for small pipes), co-rotating twin screw extruders with a 90-180 mm diameter or Tandem systems.
The foam Polyethylene and Polypropylene tubes are mainly used for thermo-insulation of piping systems which transport refrigerated or hot liquid or gases.
The extrusion lines can be equipped with a second extruder which applies a rigid skin to close the pores of the tubes over the pipe to be insulated. There is also the possibility, when the diameter is small, to extrude the expanded tube directly around the copper pipe to be insulated. Multi die heads brings the advantage to increase considerably the extrusion line output.
