10. THREADED
FLANGES
The threaded flange is similar to
the slip-on flange, but the bore
is threaded. Very important that
it can be assembled without
welding, example its use in low
pressure service at ordinary
Temperatures, and in highly
explosive areas where welding
create risk.
Standard Flanges
SLIP-ON
FLANGES
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 than
the O.D. of the matching pipe.
WELDING
NECK
The welding neck flange is
normally referred to as the "high
hub" flange. It is designed to
transfers tresses to the pipe,
there by reducing high stress
concentrations at the base of
the flange.
LAP JOINT
FLANGES
The lap joint flange is practically
identical to the slip-on flange
except it has a radius at the
intersection of the bore and
flange face. This radius is
necessary to have the flange
accommodate a lap joint stub
end. Normally, a lap joint flange
and the lap joint stub end are
mated together in an assembly
system.

11. BLIND
FLANGES
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 of
vessel once it has been sealed
and must be reopened.
Standard Flanges
SOCKET
WELDING
FLANGES
The socked welding flange is
similar to a slip-on flange except
it has a bore and a counterbore
dimension. the counterbore is
slightly larger 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.
ORIFICE
FLANGES
Orifice Flanges are intended for
use instead of standard pipe
flanges when an orifice plate or
flow nozzle must be installed.
Pairs of pressure "Tappings",
mostly on 2 sides, directly
opposite each other, are
machined into the orifice flange.
This makes separate orifice
carriers or tappings in the pipe
wall unnecessary.

12. Wind
Power Flanges

BNG Flange Group provides complete customized wind turbine tower solutions, the
dimension of wind turbine tower (include wind tower flanges), foundation structure, and
