Saddle tap assemblies comprising internal collars and external saddle taps are disclosed. A saddle tap assembly may include an external slip tap, internal tap collar, a duct section, and adhesive. The external slip tap and the internal tap collar may each have a flange. The flanges may be curved. The flange of the internal collar may have a sheared portion permitting the flange of the internal collar to pass through an opening in a section of duct. The installation of saddle tap assemblies according to embodiments of the present invention is more cost-effective and less time consuming than conventional methods. Moreover, the seals and bonds formed using embodiments of the present invention provide for several layers of chemical protection and structural stiffening wherever the saddle tap assemblies are located.

The saddle tap assembly of claim 1 further comprising: an adhesive disposed between the internal slip collar and the external saddle tap. 3. The saddle tap assembly of claim 2 further comprising: an adhesive disposed between the internal slip collar and the duct. 4. The saddle tap assembly of claim 3 further comprising: an adhesive disposed between the duct and the external saddle tap. 5. The saddle tap assembly of claim 3, wherein the adhesive disposed between the internal slip collar and the duct forms a second internal ring seal that may be exposed to corrosive environments. 6. The saddle tap assembly of claim 4, wherein the adhesive disposed between the duct and the external saddle tap forms an external sealing ring. 7. The saddle tap assembly of claim 2, wherein the adhesive disposed between the internal slip collar and the external saddle tap forms a first internal ring seal that may be exposed to corrosive environments. 8. The saddle tap assembly of claim 1, wherein the duct comprises fiber-reinforced plastic and a fluoropolymer film. 9. The assembly of claim 1, wherein the flange end of the internal slip collar comprises at least one sheared side and wherein the at least one sheared side permits the internal slip collar to fit through the opening, wherein the opening comprises one or more notches. 10. A method of installing a saddle tap assembly comprising: obtaining a section of duct;obtaining an internal slip collar with a flange end, a collar end, and a first set of one or more apertures in the flange end;obtaining an external saddle tap with a saddle flange end, and a second set of one or more apertures in the saddle flange end;cutting an opening in the duct, wherein the opening is sized to accept the collar end of the internal slip collar;disposing the internal slip collar in the opening;disposing the external saddle tap over the internal slip collar, wherein the saddle flange end is positioned over the collar end of the internal slip collar;aligning the first set of one or more apertures with the second set of one or more apertures;disposing attachment mechanisms through the first and second set of one or more apertures; andfastening the attachment mechanisms. 11. The method of claim 10 further comprising: applying an adhesive to the internal slip collar, wherein the adhesive is applied to an inside lip of the flange end of the internal slip collar. 12. The method of claim 10 further comprising: applying an adhesive to the external saddle tap, wherein the adhesive is applied to a bottom surface of the saddle flange end of the external saddle tap. 13. The method of claim 10, wherein the flange end prevents the internal slip collar from passing through the opening. 14. A method comprising: disposing an internal slip collar in an opening of a duct, wherein the internal slip collar includes one or more apertures in an internal slip collar flange end;applying an adhesive to the internal slip collar;disposing an external saddle tap over the internal slip collar, where the external saddle tap includes one or more apertures in an external saddle tap flange end;disposing attachment mechanisms through the one or more apertures in the internal slip collar flange end and the one or more apertures in the external saddle tap flange end; andfastening the attachment mechanisms. 15. The method of claim 14 further comprising: applying an adhesive to the external saddle tap. 16.
