METHOD AND APPARATUS FOR PROTECTING PIPE INSTALLED UNDERGROUND |
摘要 |
<p>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.</p> |
