초록

A pipe has an innermost layer, outside of which there is an inner electrode layer, outside of which there is an insulating layer, outside of which there is an outer electrode layer. The innermost layer is made of plastic by continuous extrusion and the insulating layer is made of foamed plastic.

대표청구항 ▼

The invention claimed is: 1. A hollow pipe made of several different materials by continuous extrusion, wherein an innermost layer is a hollow plastic layer totally covered outside by an inner electrode layer, outside of which there is an electrically insulating layer totally covered outside by an outer electrode layer, the electrically insulating layer electrically separating the electrode layers from each other and being thicker than either of the electrode layers. 2. A pipe according to claim 1 for conducting gas indoors, wherein the electrode layers are connected electrically in such a way that the perforation of the electrode layers brings about an alarm. 3. A pipe according to claim 1, wherein the electrode layers are connected electrically in such way that a strain resulting from the loading of the pipe produces a warning signal. 4. In a pipe according to claim 1, wherein the pipe is used as a ventilation or a soil and waste pipe, the improvements comprising noise detecting means and counter-wave producing means, wherein the electrode layers are connected electrically in such a way that the outer electrode layer produces a sound that is opposite to a signal measured from inside the pipe so that a counter-wave produced in the outer electrode layer muffles noise occurring inside the pipe. 5. In a hollow pipe, the improvements comprising a hollow innermost layer totally covered outside by an inner electrode layer, outside of which there is an electrically insulating layer totally covered outside by an outer electrode layer, wherein the innermost layer is plastic of continuous extrusion, the electrically insulating layer is foamed plastic, and the electrically insulating layer electrically separates the electrode layers from each other. 6. A pipe according to claim 5, wherein the foamed plastic contains holes. 7. A pipe according to claim 6, wherein cells of the foamed plastic comprise a filler. 8. A pipe according to claim 5, wherein cells of the foamed plastic comprise a filler. 9. A pipe according to claim 5, wherein the electrode layers are connected electrically in such a way that a perforation of the electrode layers makes a short circuit. 10. A pipe according to claim 5, wherein the electrode layers are connected electrically in such a way that a strain from loading of the pipe changes a potential difference between the electrode layers. 11. A pipe according to claim 5, wherein the inner electrode layer, the electrically insulating layer and the outer electrode layer are formed simultaneously by continuous extrusion. 12. A pipe according to claim 11, wherein the foamed plastic contains holes. 13. A pipe according to claim 12, wherein cells of the foamed plastic comprise a filler. 14. A pipe according to claim 11, wherein cells of the foamed plastic comprise a filler. 15. A pipe according to claim 11, wherein the electrode layers are connected electrically in such a way that a perforation of the electrode layers makes a short circuit. 16. A pipe according to claim 11, wherein the electrode layers are connected electrically in such a way that a strain from loading of at least one of the layers changes a potential difference between the electrode layers.
