7. Hopper Section Assembly
PNEG-805 36' Diameter 40°/45° NCHT Commercial Hopper Tanks 29
Install Hopper Panels
The 36' hopper bottom has three (3) sections. Apply caulk to all hopper section seams as shown
in
Figure 7H on Page 30 .
Step 1: Attach all the top panels to the compression angles using bolts. See chart below for bolt
specifications. Install the compression splice plates on the back side of the compression angle.
(See Figure 7E.) All top panel overlap seams use 1/2" x 1" bolts. Lap all panels as shown in Figure 7F .
Step 2: Assemble the left and right sides of the middle section to the top sections that were just installed.
Use 1/2" x 1" bolts for all middle section seams. Use 1/2" x 1-1/2" bolts at the corners of the panels where
three (3) or more panels overlap. Lap all panels as shown in
Figure 7F .
Step 3: Once the middle panels are installed the bottom hopper panels and discharge collar may be
attached with 1/2" x 1" bolts at four (4) opposing points as shown in
Figure 7I on Page 30 . Complete this
assembly by laying the remaining panels - moving around in one direction and lapping all sheets the same
way. Do not tighten bolts until all hopper panels are attached to each other, the compression ring,
splice plates and discharge collar.
NOTE: All bolts used in hopper assembly should be installed with the bolt heads to the inside of the hopper.
