HOB-O Provides Economic Solution!

From BUG-O Systems, Inc.
 

 

The Illinois Power Company was spending too much time and money removing and reinstalling torus rings on high pressure feedwater heaters, due to quality and productivity problems. Previously, torus rings were removed by flame cutting (oxy-acetylene) by hand with the assistance of a fixture. The resulting kerf was often very rough and not in the same plane. To make the joint acceptable for rewelding, a considerable amount of time was spent grinding, building up low areas by welding, and then re-grinding. If the torus ring was not severed in the same plane, fit-up problems had to be overcome upon reinstallation.
