REPAIR APPARATUS AND METHOD

摘要

A repair device may include a cured-in-place liner having a modification to prevent adhesion of the liner adjacent to an opening in a pipe during the curing process and where a fire activated device has previously been installed/located. The liner may also soften and give way under specific time/temperature exposure that permits an existing fire-stop device to function properly and as designed in a fire event while preventing that device from deploying prematurely and/or by failure of the existing strap, fitting and/or other design deficiency.
