| Abstract: | After experiments in scale dissolving and erosion, a special cleaning process has been de- signed to deal with the sulfate scale produced in heat transmission equipment. This process employs both acid cleaning and neutral cleaning in two steps, which proves to be effective in cleaning the cop- per tube without any erosion |
