ABSTRACT:
A retainer shield for a split ring retains boiler tubes aligned therein and dissipates heat from a front weld thereon. The retainer shield is preferably made from about 50% chromium and about 50% nickel and is welded to one end of the split ring to assist in holding the two halves of the split ring together. The retainer shield draws heat therefrom and dissipates it to prevent oxidation of the welds holding the two halves of the split ring together.
