Anchoring refractory lining - to heat exchanger cooled tube wall using helical springs welded at intervals

A cooling tube wall for heat exchangers has helical fixing devices for refractory material; the fixings comprise helical wires fitting into the valleys between adjacent tubes and in contact at intervals with the tubes; the windings are open-coiled and are tack-welded to the tubes. The helix axis may be parallel to the tube axis, or alternatively transverse to the tube axis, in which case the pitch of the turns equals the spacing of the tubes. The wires may be constructed as close-coil arrangements, e.g. of stainless steel, and then stretched and tack-welded at appropriate positions to the tubes.
