众所周知，管道可以是运输不同性质的多相流体的安全和环境/经济上合理的手段;然而，如果没有良好的监测，它们可能对健康和环境构成严重威胁。操作和监测方法正在改进，但也存在新的挑战，主要是由于输送流体的质量，特别是碳氢化合物的质量。举几个例子，原油通常含有H2S;建造了运输和注入超临界流体的新管道;由于生物燃料引起的仅部分已知的破坏机制以及外部侵蚀性环境（例如深海水），可能会出现新的腐蚀问题。经过40多年的腐蚀领域的工作，通常是在与管道相关的项目中，在本文中，作者将试图从石油和天然气行业的前雇员和该行业目前的顾问的部分角度总结主要的损坏机制，现有知识和未来的公开威胁。
As it is widely known, pipelines can be a safe and environmentally/economically sound means to transport multiphase fluid of different nature; if not well monitored, however, they can pose a serious threat to health and environment. Operational and monitoring methods are improving, but new challenges are also present, mainly due to the quality of transported fluids, especially in the case of hydrocarbons. To quote a few, crude oil often contains H2S; new pipelines transporting and injecting supercritical fluids are built; new corrosion problems can occur due to the—only partially known—damage mechanisms caused by biofuels, and to external aggressive environments as for instance deep sea water. After more then 40 years of work in the field of corrosion, often in projects specifically related to pipelines, in the present paper the author will try to make a summary of the principal damage mechanisms, the present knowledge and the open threats for the future, from the partial point of view of a former employee of the Oil&Gas industry and at present consultant in that sector.
