These segmented rings are fabricated from 2-lb density polystyrene foam, for the purpose of supporting gas pipelines during above ground handling and provide spacing when the pipes are lowered into the trench.
Because the rings are soft and non-abrasive they help to protect the pipe from scratches and nicks during handling. When the pipe is in the trench, they provide spacing and guidelines for compacting sand around the pipe.
