ESCO Membrane and Overlay Heads are patented and feature a Golf T shaped cutting insert that requires no screws to hold it securely in place.
ESCO Membrane Heads fit over the tube O.D. and remove the membrane from between boiler waterwall tubes while not degregating the tube O.D. Membrane/Overlay Heads also remove membrane from between tubes and weld overlay from the tube O.D. Both Membrane and Membrane/Overlay Heads are mounted to a Base Head.
