ABSTRACT:
A thermal insulator for pipe elbows and the like, comprises two pairs of split, sleeve-shaped insulative legs having interior channels in which those pipe sections joined by the elbow are received. The insulator legs include dihedral faces which are oriented toward each other at a medial portion of the elbow, and are formed by inner and outer surfaces which intersect at the central axis of the associated leg. These leg surfaces are inclined at an angle equal to a predetermined fraction of the included angle between the joined pipe sections. The inner faces of the insulator legs abut, and a wedge-shaped collar or gore is disposed between the outer leg surfaces, and includes inclined faces which mate therewith, thereby forming a closed, insulative sleeve about the pipe elbow.
