Abstract: A borehole pipe protection apparatus includes a sheet of material having an inner surface and an outer surface and a longitudinal direction and a width direction defined by two edges of the sheet along the longitudinal direction. A fastening structure is configured to join the two edges to form a seam as the sheet of material is wrapped in the width direction around a pipe that is configured to be installed into the borehole to form a sock along the longitudinal direction. The sock is configured to be installed in the borehole with the pipe about which it is wrapped, yet to remain for a service life in non-bonding contact with the pipe. A method for protecting pipe during and after insertion into a borehole is also described.

Abstract: A pipe protection apparatus includes a sheet of permeable material having an inner surface and an outer surface and a longitudinal direction and a width direction defined by two edges of the sheet along the longitudinal direction. A fastening structure is configured to join the two edges to form a seam as the sheet of permeable material is wrapped in the width direction around a drain pipe configured to be installed underground to form a sock along the longitudinal direction. The sock is configured to be installed underground with the drain pipe about which it is wrapped, yet to remain for a service life in non-bonding contact with the pipe.

Abstract: A coupler apparatus for installing a pipe and a protective cover into a borehole includes a first coupler half and a second coupler half. Both halves include a leading edge and at least one slot disposed in an outer surface configured to allow a fluid to pass by the coupler apparatus as the coupler apparatus is pulled through the borehole. A fastening means joins the first coupler half to the second coupler half about the pipe and the protective cover. The coupler apparatus formed by the first coupler half joined to the second coupler is configured to capture the protective cover at a location on the pipe for the installation of the pipe with the protective cover into the borehole. A method is also described.
