5. 15'-24' Hopper Assembly
PNEG-1070 15', 18', 21', 24', 27' and 30' CHT’s 35
Begin assembling the hopper bottom by attaching a right and left pair or pairs of hopper panels to the
compression angle ring (3/8" x 1" bin bolt (S-455)) and discharge collar (1/2" x 1" hardware (S-4492)) at
four (4) opposing points as shown in
Figure 5D . Caulking is required on the vertical seams of the lapped
hopper panels (Refer to Figure 5G ). Splice plates which join the compression angle segments on the
back side may be installed following a pair of hopper panels. Refer to Figure 5F . Complete this assembly
by laying in alternate right and left panels moving around in one direction and lapping all sheets the
same way,
See Figure 5E . Do not tighten bolts until all hopper panels are attached to each other, the
compression angle, splice plates and discharge collar.
On 15' through 24' tanks use 1/2" bolts on hopper seams.
NOTE: All bolts used in hopper assembly should be installed with the bolt heads to the inside of
the hopper.
