Title:
Heat treatment equipment for the inner surface of tubular or other enclosed structures
Document Type and Number:
Japanese Patent JP6363178
Kind Code:
B2
Abstract:
A heat treatment apparatus for heat treating an interior surface of a longitudinally extending cavity of a target structure has a processing head which comprises a longitudinally extending central support member and distal and proximal end caps protruding laterally from the central support member. Each end cap has a plurality of apertures configured to respectively receive distal and proximal ends of elongated plasma arc lamps and position the plasma arc lamps to extend longitudinally along and laterally around the central support member such that radiation emitted collectively by the plasma arc lamps is directed generally radially outwards from the processing head. The processing head also comprises a coolant pathway having heat exchange zones in thermal communication with the plasma arc lamps and coolant supply and return conduits in fluid communication with the heat exchange zones.
