Expansion joints cleaning

Cannot clean or inspect shell Bundle is replaceable > Limited to temperature difference of 200°F without costly shell expansion joint... 

Removable tube bundle permits easy internal cleaning. Design allows free expansion of tubes in high-temperature service. Needs no expansion joint if shell is used. 

Isolating equipment, removing expansion joints, rupture discs and relief valves from pipework and equipment before line Rushing, cleaning and testing. 

Bridge walls of brick running down the center of the furnace may be used to achieve better control of the heat distribution inside the unit as seen in Figure 4. Care must be taken during shutdowns to clean out and repack the expansion joints to accommodate the thermal expansion that will occur when the furnace is brought on-line. Figure 5 shows the effect of inadequate expansion allowance in a division wall. It is imperative that all the expansion joints be fully functional to avoid buckling of the wall. 

To minimize microbial contamination, all floors should be easy to clean, impervious to water and laid on a flat surface, hi some areas it be necessary for the floor to slope towards a drain, in which case the gradient should be such that no pools of water form. Any joints in the floor, necessary for expansion, should be adequately sealed. The floor-to-wall junction should be coved. 

After Ed s move to Einstein in 1956, a joint U.S. patent in the public interests was filed (together with H. M. Tsuchiya and N. N. Heilman) on the practical production of the Streptococcus DS-50 dextran. Pilot plant production was undertaken at NRRL clean-up and bottling were carried out as a service by the Cutter Corp. and a successful clinical trial of the dextran for treatment of patients in shock was conducted by Dr. W. Metcalf of Einstein s Department of Surgery. Ed presented a final report to the National Research Council in 1962. In the end, despite the discovery of a simpler way to manufacture a product of great potential military usefulness, dextran in general would be replaced by blood and plasma as agents of plasma volume expansion in shock patients.
