ABSTRACT:
A unitary spiral ring structure is fabricated from side-by-side split ring members with one end of one ring joined in overlapping relation to one end of the other ring by means of a silver soldered or other fused metal joint. The mating ends of each ring member are interlocking with the free ends being radially confined by the respective joined ends. An auxiliary expansion ring improves the sealing of the spiral ring.
