Question 249Steam Plants - 1st Asst/Chief

The correct answer is B) Filling the cut by welding and then grinding it smooth. This is the correct method because welding is the most effective way to repair a steam cut on a seating surface. Welding allows the cut to be filled and the surface to be restored to its original condition. The welded area can then be ground smooth to ensure a proper seal between the handhole plate and the superheater. The other options are not as effective. A) Filling the cut with iron cement or plastic steel may temporarily seal the cut, but it is not a permanent repair. C) Refacing the surface and over-torquing the handhole plate may not fully address the underlying issue of the steam cut. D) Grinding the seating surface and installing an oversized gasket may work, but it does not actually repair the cut itself.
