Points : Boiler Tube Repairs, Definition Definition An enhanced way for the speedy and efficient repair of tubes controlled in a furnace boiler water wall involve milling an elongated slot at both end of a damaged tube sector in a water wall, which section is thereafter cut away and replace by a replacement tube section having elongated slots milled at all end which are cut to companion to existing tubes. The replacement tube section and offered tubes are aligned to type elongated slots through which interior welds are complete to safe the replacement tube section. The elongated slots are then blocked with covers cut from a second section of alternate tubing, and the water wall web is close to the replacement tube section to absolute the repair. Also disclosed are a milling machine used to mill the elongated slots, and drill and saw fixtures to aid in cutting away the damaged tube section. The better method and apparatus enhance the precision and regularity with which boiler tube repairs might be made, increase contact to perform internal welds in boiler tubes and allow some prefabrication of essential repair parts, thus reducing furnace down time for mend.
