TDS Repair Technique
Usually flange gaskets can
be drilled as seen in Figure (2). However,
there are times when the technician cannot get sealant travel in
the groove. If this is the case, measurements will have to
be taken in order to design a clamp that will enclose the split
line of the two flanges. Additionally the bolt holes will
have to be drilled and injected with sealant to prevent leakage
from the bolt holes.
