Internally lined pipe connections and related methods of makeup

A method of assembling a threaded connection, the method comprising:

• providing a first pipe having an internal liner and a first pin end on a distal end thereof, the first pin end comprising a first annular seal permanently affixed therein, the first annular seal comprising an annular groove formed on an inner surface of the first annular seal and extending in a radial direction such that the annular groove is in communication with the through-bore of the threaded connection;
• providing a second pipe having an internal liner and a second pin end on a distal end thereof, the second pin end comprising a second annular seal permanently affixed therein;
• providing a coupling comprising first and second box ends;
• threadedly engaging the first pin end with the first box end, and the second pin end with the second box end, allowing the first and second annular seals to axially compress under a load parallel to the central axis of the threaded connection;
• and
• contacting a mating surface of the first annular seal with a mating surface of the second annular seal at an angle to provide a continuous internal seal along an axial length of the threaded connection.
