Our gas pipeline network in Spain is more than 11,000 km long. At Enagás we are responsible for operating, maintaining and supervising this entire infrastructure network on an uninterrupted basis, 365 days a year.
The maximum pressure that gas pipelines of the trunk network can withstand is 72 or 80 bars, depending on the design of each section, and the minimum is 30 bars. The only exceptions are the underwater sections, such as the Almería international connection and the pipeline that connects Denia to the Balearic Islands, which have a design pressure of 220 bars.
The table below shows a breakdown of the largest gas pipelines and sections in the country. Enagás updates this information every six months.
