Top hat liner having integrated thermoplastic with improved melt-flow characteristics for connection of main and lateral pipes in cured in place pipe systems and associated method of use

摘要

A flexible top hat for use in the pipe junction between a main pipe and lateral pipe is used in conjunction with a CIPP system, and is preferably constructed of material having a melt/flow point, cure point and bonding point temperature and pressure that is substantially similar to the CIPP. The CIPP system and top hat are cured together to form a unitary structure.
