Natural Gas Pipelines

Long pipelines built to carry natural gas across countries, seas and continents, including undersea lines that move gas from producing regions to distant markets without crossing the land routes of transit states. An entry belongs here when the cited article calls the pipeline a natural gas pipeline or gas transmission system. It excludes crude oil pipelines, which have their own group. Entries are placed by what their own cited article says, so each one sits in the narrowest group its source supports, and the group page lists it beside the other members.
