Abstract
Systems, apparatus and methods for hot tapping into pressurized, coated duct systems for transporting corrosive substances are disclosed. A branch line may be installed in such systems without shutting down or depressurizing the system using the disclosed systems, apparatus and methods without compromising the system coating or resistance to corrosion from the transported substances. Cut edges created when ductwork is cut to install a branch line are captured and sealed between two gaskets, avoiding the need for recoating with difficult to apply corrosive protection materials such as fluoropolymer coatings.
