CHAPTER I!, SECTION 5 Figure 2-155. Station 2220 - Supports for Pipes ; _~ 2-155 shows the supports and distance between pipes near Station 2200. Figure 2-156 notes the supports and hardware installed near Station 50. Difficulties arose when the fiber glass pipe joints and neoprene expansion joints collapsed under the applied vacuum. Fibre glass pipe was replaced with steel pipe, and new neoprene expansion joints with a greater wall thickness were installed. Figure 2-157 shows pipes entering Station 2210. At the rear of Station 2210 is shown Station 2200. The earthfill has been completed and is being covered with sand bags. The sheet metal siding has been removed from Station 2210. STATION 2221.01 AND 2221.02. PUMP STATION - SITE TARE-SUGAR JSER: UCRL GENERAL.Station 2221.02 consisted of vacuum pumps mounted on 4°-0" x 5°-0" x 0-4” Figure 2-156. Station 2220 - Hardware Installed thick reinforcee concrete pads which were embedded three inches in the ground. This was the permanent pumping Station for holding Station 2200 pipeline under a pressure of 1 cm Hg. absolute or less. The Station consisted of two 5HP vacuum pumps connected into the pipelines through sediment separators and flexible hose connections. Salt water was pumped from a well and used as a medium for cooling the vacuum pumps. Valved stub-outs were included in the piping for the possible connection of two portable vacuum pumps. iMfo Fa yes ON a a ate ere ee a epee aE en ee Figure 2-157.
