Installation steps
Follow these steps to install the PMW paper mill seal:
Procedure
1. Using the appropriate size hole saw, cut a hole in the process vessel to accept the
lower housing. The diameter for a lower housing with a heat isolator groove is 1.32-
in. (33,4 mm). The hole should produce a tight, uniform fit when coupled with the
lower housing.
2. Bevel the edge of the vessel hole to accept filler material (see
no larger than 37.5° is recommended; see ASME B16.25 for more details. Bevels can
be made on one or both sides of the tank. Do not grind or cut the bevel to a sharp
point. Attempt to leave a flat area. The flat area should be large enough to minimize
spud distortion but small enough so that tank weld requirements can be met.
Minimizing the bevel angle will decrease the amount of fill required during weld and
