The production starts with the extrusion of the core hose. The next step is the wrapping of the hose with a wire mesh in a spinning unit. As the winding-on of the fabric has to be done with some tension it is necessary to stabilize the core hose to eliminate the occurence of deformation. The standard procedure uses a supporting cotton fabric. This requires a second spinning unit.
The easier way is to use our hose cooling units. Before entering the spinning unit the hose passes through a hose cooling unit. The cooling chamber has a length of approximately 2 m. On the inside liquid nitrogen (LIN) with a temperature of -196°C is sprayed on the hose. Passing through the unit, the hose gets colder and becomes stiff enough for the subsequent winding-up of the wire mesh.
You will benefit from:
- No usage of hydrocarbons
- Flexible cooling power
- Easy operation
- Easy maintenance
- Our standard hose cooling units allow a maximum hose diameter of 50 mm. Other sizes on request.
