Method and apparatus for constructing buried pipeline systems

Patent ·
OSTI ID:6599732
A method and apparatus for mitigating or eliminating the frost heave of refrigerated pipelines buried in frost-susceptible soil are provided. A blanket of heat absorbent material is placed over the pipeline on the surface of the soil to increase the flow of heat into the region surrounding the pipeline. This technique may be used in combination with other frost heave mitigation techniques, such as insulating the pipeline and supporting the pipeline with a heave resistant bedding material.
