How to identify a gas pipeline

Natural gas pipelines are marked along the way with signposts, plates or other markings to prevent accidental damage. The colour code used for the above-ground high-pressure transmission pipelines is purple and for the above-ground distribution and installation pipelines yellow.  The markings on transmission pipelines feature black text on a yellow background.

In forest areas and built-up areas, a natural gas pipeline can be spotted on the basis of a treeless zone that is 5–10 m wide. All construction work is forbidden within 5 m from a gas pipeline without authorisation by the pipeline owner.

Here is what an excavation prohibition sign looks like:

Pipeline locations

Our transmission pipelines are located in southern Finland. The map application shows the gas pipelines, the related pressure reduction stations acting as customer interfaces, and the signposts. Click on the link to access the application that shows you the pipeline locations and the safety distances relating to construction work. The map also shows the locations of the anode fields relating to the electrical corrosion protection of pipelines. Use the layer menu to view the safety distances relating to various activities. You can also use the map service to request a statement.

Operating on gas pipelines

It is prohibited to cross a gas pipeline with heavy equipment in unreinforced sections or to work within 5 m from a gas pipeline without Gasgrid Finland’s authorisation and supervision. If you have plans for land use in the vicinity of a natural gas pipeline, study our guidelines and contact our supervisors. Our supervisor will visit the site free of charge and show you the exact location of the gas pipeline. Any drainage ditch clearing and finishing work on ground surface must take place under the supervision of our supervisor.

If you are planning work near a gas pipeline, contact us preferably three working days before your scheduled workday on +358 20 447 8713. Our supervisor will visit the site free of charge.

The transmission pipeline system has been divided into four areas as regards on-site pipeline location guidance and pipeline crossings, earthworks and statements required for projects in the vicinity of transmission pipelines. If you have any questions about geographic data or written authorisations relating to pipelines, you will find the contact details here. On-site pipeline location guidance, crossings at unreinforced sections, construction and projects requiring a statement are also supervised by area in accordance with the contact details form.
