Method for cutting and obturating pressurised gas pipelines |
摘要 |
<p>The method involves forming a bush shaped end plate (6) as closure unit, which is attached to the gas pipeline (3) by material engagement. The local gas pipeline is provided in axial direction in the area of the end plate, such that in the foam plug a channel is created, through which the gas advances to the connection portion (7) that is made by material engagement between the end plate and gas pipeline. An independent claim is also included for a device for separation and long lasting opening of gas pipelines under pressure.</p> |
