High Pressure Pipelines for Natural Gas - Recommendation for Corrosion Protection at Road or Railway Crossings
This recommendation was drawn up by the Swedish Corrosion Institute after consultation with several Swedish authorities and private companies. It is recommended that pipelines are installed without casings in all places possible. If casings must be used and steel casings are chosen they should be provided with an external protective coating with good resistance to mechanical damage unless the corrosivity of the soil is proven to be low and no metallic contact between casing and gas pipe can be anticipated. Concrete casings need no coating unless the soil is aggressive to concrete. Where casings are used extra internal cathodic protection with the anodes placed in the space between the pipes should be installed. (ERA citation 10:046089)
