<p>In order to overcome the problems that earlier apparatus have experienced, a pipeline apparatus (10) for liquid cryogen is proposed, comprising:
- a first assembly or first insert (18) including
-- a first pipe (12) having a first exterior surface and a first passageway for the liquid cryogen, and
-- a longitudinal member (14, 15) extending along a portion of the first exterior surface of the first pipe (12);
- a second pipe (20) having a second passageway sized and shaped to receive the first assembly or first insert (18) therein, the second pipe (20) coacting with the longitudinal member (14, 15) to provide a pair of channels (16, 17) in the second passageway; and
- a third pipe (21) having a third passageway sized and shaped to receive the second pipe (20) therein, the third pipe (21) spaced apart from the second pipe (20).</p> |
