| 摘要 |
The present invention relates to a method of jointing multilayer pipes and a pipeline formed by multilayer pipes. According to the method there is formed at least one aperture in the pipe wall at the joint, the aperture extending to through the wall from the non-conductive layer to the conductive layer, and the aperture is filled with conductive material, which forms a conductive bridge from the conductive layer through the non-conductive layer to the outside thereof for grounding of the conductive layer. By means of the invention, the pipes can be grounded without a change in the dimensions of the pipe or in the pressure rating of the pipe. |
