Buried Pipelines - an overview ScienceDirect Topics

B. Tribollet, M. Meyer, in Underground Pipeline Corrosion, 2014 Abstract:Pipelines buried in soil are protected by a thick organic coating complemented by cathodic protection (CP). In spite of this double protection, when these pipelines are in the vicinity of a high voltage AC electrical field, such as a power line or an electrical railway for instance, corrosion may occur at the location of Mitigation of External Corrosion on Buried Carbon Steel 4. Two (2) Layer Extruded Polyethylene (e.g., YJ1, Yellow Jacket) Rubber-modified asphalt adhesive covered by an extruded polyethylene outer sheath 5. Thermally insulated pipeline coatings such as:Polyurethane foam applied direct to pipe, polyethylene tape or extruded

Pipe Jacketing McMaster-Carr

This very rigid insulation offers the lowest heat-flow rate of our pipe insulation and restricts absorption of water, air, and gas. It is typically used in process piping and chiller plants and performs best in applications below 50° F.

Application Direct Buried Pipeline Freeze Protection

InstallationThe installation of our direct burial heat trace is made simple by attaching it to any plastic or steel pipeline using our metallic heat transfer tape assuring all heat energy is efficiently transfer to the pipeline. For most applications below the Arctic Circle lines need to be buried a minimum of 24. All exposed piping will need a minimum or 2 water proof insulation.
