ABSTRACT:
A pipeline clamp for securing a heated arctic pipeline to its support structure comprises a sandwich material of inner and outer layers of fiber reinforced rigid polymer and an intermediate core layer of honeycomb-form aramid paper. The clamp affords all the engineering advantages of prior steel clamps without the disadvantages of being heat conductive which can result in conductance of pipeline heat to the permafrost layer as well as "freezing out" of low melting paraffins flowing within the pipeline which decrease pipeline efficiencies.
