The slip-on flange has a low hub because the pipe slips into the flange
prior to welding. It is welded both inside and out to provide sufficient
strength and prevent leakage. Slip-on flanges are all bored slightly larger
that the O.D. of the matching pipe. They are preferred over welding neck
flanges by many users due to their lower initial cost, but final installation
cost is probably not much less than that of the welding neck flange because
of the additional welding involved.
The lap joint flange is practically identical to a slip-on flange except
it has a radius at the intersection of the bore and flange race. This
radius is necessary to have the flange accommodate a lap joint stub end.
Normally, a lap joint flange and a lap joint stub end are mated together
in an assembly system.
The blind flange is a flange
without a bore. It is used to close off the ends of a piping system and/or
a pressure vessel opening. It also permits easy access to the interior
of a line or vessel once it has been sealed and must be reopened.
The socket welding flange is similar to a slip-on flange except it has
a bore and a counter bore dimension. The counter bore is slightly lager
than the O.D. of the matching pipe, allowing the pipe to be inserted into
the flange similar to a slip-on flange. The diameter of the smaller bore
is the same as the I.D. of the matching pipe. A restriction is built into
the bottom of the bore which sets as a shoulder for the pipe to rest on.
This eliminates any restriction in flow when using a socket welding flange.
