Thermal expansion connection for rigid pipes

A thermal expansion connection for connecting a first rigid pipe to a second rigid pipe, each of the first and second rigid pipes defining a first diameter, said thermal expansion connection comprising:

• a distal end defined by said first rigid pipe, said first rigid pipe distal end defining a first radial recess and a second radial recess;
• a first seal and a second seal disposed on said first rigid pipe distal end, said first seal being disposed within said first radial recess and said second seal being disposed within said second radial recess, said first and second radial recess defining a depth approximate a radius of said first and second seals;
• and
• a proximal end defined by said second rigid pipe, said proximal end defining a collar defining a second diameter dimensioned to receive said first rigid pipe distal end and said first and second seals disposed on said first rigid pipe distal end, whereby a gap is defined between said first rigid pipe distal end and said second rigid pipe collar, and whereby a dynamic connection is formed to permit linear movement between said first rigid pipe and said second rigid pipe, said second rigid pipe collar being swaged to compress said first and second seals to prevent extraction of said first rigid pipe distal end from within said second rigid pipe collar.

• and
• a proximal end defined by said second rigid pipe, said proximal end defining a collar defining a second diameter dimensioned to receive said first rigid pipe distal end and said first and second seals disposed on said first rigid pipe distal end, whereby a gap is defined between said first rigid pipe distal end and said second rigid pipe collar, and whereby a dynamic connection is formed to permit linear movement between said first rigid pipe and said second rigid pipe, said second rigid pipe collar being swaged to compress said first and second seals to prevent extraction of said first rigid pipe distal end from within said second rigid pipe collar, said second rigid pipe collar terminating in an inwardly extending flange.
