How should workpiece impact protection be specified for industrial heating elements?
Impact protection for industrial heating elements begins with the workpiece handling path: define minimum clearance from lifting and loading trajectories, then add baffles, guide rails or removable guards that do not block radiant heat transfer. Specify sheath diameter, material, watt density and surface load so the element runs within its allowable temperature. At acceptance, check clearances with gauges, inspect for bent or scored sheaths, and record control-loop response. Any sign of impact during service calls for insulation-resistance and leakage-current retesting before reuse.
