Method of Removing Boiler Tubes
A Boiler Tube Removal is normally accomplished by cutting the tubes at their outer periphery, heating the stub of the tube, notching the forks of the torches, and thereby forcing the tube loose from the boiler vessel. Boiler tube removal may involve cutting off the tubes close to the exterior periphery of the boiler vessel until the tubes can be removed. To remove boiler tubes from a boiler vessel without damaging it, it is necessary to sever the boiler tube near the exterior perimeter of the vessel, and then to remove all but a thin shell of the severed boiler tube with a piloted rotary cutting tool placed in relation to the longitudinal axis of the severed boiler tube. The rotary cutting tool is then withdrawn from the boiler vessel opening, and the remaining thin shell of the boiler tube is manually peeled away from the periphery of the opening in the boiler vessel. This method of cutting rotary tubes is particularly useful in preventing the expansion of the boiler tube...
