W.hat Does Damage Limitation Mean?

D.amage limitation is the process of ensuring that the valves fitted to pipelines are in good operating condition to minimize the damage that will be caused in case a pipeline experiences failure. Failure can be caused due to a variety of reasons including mechanical and manufacturing defects, human error and acts of nature.

T.renchless construction techniques require the laying of pipes using methods such as directional drilling, auger boring and microtunneling, which are performed below the ground surface. If care is not taken, it is possible to damage the pipeline during the process.

石油，天然气和化学管道携带需要持续监测泄漏的危险材料。在铺设这些管道的同时，管道可能通过镗孔仪或反铲牙齿造成机械损坏。

由于天然灾难，也可能发生对管道的结构损坏。

机械损坏本质上很小，因此可以在很长一段时间内被忽视。然而;这些小损害可以通过压力来增强，导致疲劳和压力撕裂，最终导致重大失败。为防止这种情况，操作阀应处于良好状态，以确保通过关闭阀门可以隔离受影响的管道。

进行定期内联检查可以帮助通过早期检测损坏来及时修理。
