Mounting Procedure (with optional
Grounding Rings GR1 for sizes up to
1000 mm (40 in.)):
1. Handles of the grounding ring have some
holes which correspond to outer diameter
of each flange type. There are printings
near each hole. The printings show types
of flange. See the table below.

2. Confirm the centering pin is fixed to the
hole corresponding to flange or fix the
centering pin to the correct hole.
3. Hang the grounding rings with their
flange type printings outer side of the
flowtube. Set the angle of both handles
symmetrically to be 45 degree from top. If
there are any bolt-holes under the handles,
turn the grounding rings clockwise in order
to locate handles between bolt-holes.
Center the grounding ring to the center of
the flowtube.
4. Connect the wire from the grounding ring
to the screw of the flowtube’s flange and fix
the wire by the nut. This procedure (item 1
to 4) must be done for the both sides of the
flowtube.
5. Install the flowtube into the customer’s pipe
with the gaskets A.

Rings GR1 for sizes up to 1000 mm
(40 in.)
Mounting Procedure (with optional
Grounding Rings GR1 for sizes 1100mm (44
in.)) and above :
1. The grounding ring is temporarily fixed
onto the flowtube by four bolts. Hang the
grounding ring up using a crane or a hoist
so that it would not fall down from the
flowtube while setting the gasket B.
2. Unfasten the bolts and remove the
grounding ring off from the flowtube.
3. Place the gasket B to the flowtube. Cut out
holes on the gasket B if necessary, so that
the bolts can go through. Fix the grounding
ring to the flowtube by the four bolts again.
4. Connect the wire from the grounding ring
to the screw at the flowtube flange and fix
the wire by the nut. This procedure (item 1
to 4) must be done for the both sides of the
flowtube.
