High pressure hoses normally consist of two layers of rubber with an intermediate wire fabric. This is necessary to prevent the hoses from burst damage. 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.
