Packing house and cold storage construction; a general reference work on the planning, construction and equipment of modern American meat packing plants, with special reference to the requirements of the United States government, and a complete treatise on the design of cold storage plants, including refrigeration, insulation and cost data .. . o the discretion of the contractor what constitutes a sub-stantial, serviceable hanger. This may not always be satis-factory, since it gives the contractor an opportunity to putin something just as good. In fireproof buildings, with the best of equipment, thelife of the hanger should, at least, be equal to that of thepiping, and they should be of rigid construction and sub- 212 REFRIGERATION stantially put up, so as to carry the weight of the pipmgwhen this is covered with ice. In pipe lofts, where a de-frosting system is used, the hangers should be galvanizedby the hot process, so as to withstand the action of the saltbrine. In buildings of wood construction the hangersshould be bolted to the ceiling and not fastened by lagscrews, which is the method generally used by should be used in concrete ceilings instead of bolts,so that the supports can be renewed, if they rust out. The following illustration shows methods of support-ing the pipes under various FIG. 122—ARRANGEMENT OF PIPES OVER HOG COOLER. In Figures 121 and 122 is illustrated the piping in beefand hog coolers. The hangers are supported from the ceil-ing above and bolted to the inserts, which are built into theconcrete. The advantage of this construction over anymethod which supports the pipes from below is piping is not affected by the vibration of the timberconstruction in the cooler, due to beef and hogs beingpushed along the rails. It also leaves the drip-pan free ofany obstructions which may interfere with the properdrainage. REFRIGERATION 213 The hangers are made from %x2y2-inch iron and thepipes rest on s^-inch
