26 PNEG-603 4" Commercial Hopper Tank
Hopper Bottom
Begin assembling the hopper bottom by attaching a right and left pair or pairs of hopper panels to the
compression angle ring (5/8" x 1-1/2" hex head bolts) and discharge collar (3/8" x 1" hex flange head bolts)
at four (4) opposing points.
(See Figure 6F.) The left and right hopper panels can be assembled (3/8" x 1"
hex flange head bolts) prior to attachment to the compression ring. Caulking is required on the vertical
seams of the lapped hopper panels.
(See Figure 6C.) Complete assembly by positioning pairs of right
and left hopper panels while moving around in one direction and lapping all sheets in the same way.
(See Figure 6D.) Do not tighten bolts until all hopper panels are attached to each other, the compression
ring and discharge collar. When ready to tighten, start at the bottom of the hopper and tighten all bolts.
This will include hopper panels bolts, hopper collar bolts, compression ring bolts, compression splice bolts,
column bracing bolts and anchor bolts.
NOTE: All bolts used in hopper assembly should be installed with the bolt heads to the inside of the hopper.
