Production line facilities' liavc liecn set Victaulic Pipe Couplings up in tlic Kokomo plant to build one com plete boat every 2 hours; i.c., 4 lioatt in one 8-hour shift. It is contemplated tliat under the rapidly increasing shipbuilding program, this rate wilt he stepped up to 8 or 12 boats |>er day. Pi|>c systems in a ship call for greater consideration than most pi|>e jobs on laud because of the severe stresses encountered in ship operation. Pipe couplings manufac tured by the Victaulic Company of Amer ica, New York, provide advantages which have helped solve many problems of marine Magnesia Pipe and Boiler designers and builders. They are now serv ing or being fitted into a majority of the Insulation Liberty ships. The Victualic joint is simple and rapidly Msin stem frame leaded for shipment struction. Each stern-frame casting is .made in one piece and weighs' on an aver age 30,100 pounds. Stem-frame castings usually require from 2 to 4 weeks to manufacture, and when quantity production was demanded by the emergency, steps were taken to increase output considerably. - Old methods were completely discarded and instead of using a complete pattern as formerly, it is how cut into many parts, placed upon board j, and cores are rammed up by a sand stinger. After drying these are fitted up in pits ready for the casting. With this change in manufacture, Penn Steel Castings Corporation is able to pro duce four .Liberty ship stern frames and two complete sets of other type stem frames High-cfliciency heat insulation for boilers and piping on Liberty ships was supplied by The Philip Carey Manufacturing Com pany, Cincinnati For this purpose 85 per cent magnesia is principally used. In general, there is no need to remove this heat insulation except at the top of the engine and at the flanged joints of the piping. To facilitate quick removal and replacement, the insulation for these portions is of unique construction and con sists of pads or quilts of asbestos cloth filled with long fiber springy "Amosite'' asbestos. These covers for the pipe flanges are equipiicd with hunks and eyes by means of which the covers arc held in place with wire lacing which can be quickly re moved or applied for quick repairs. . The top of the engirt: is covered with a sheet metal cover lined with this same type of asbestos pad insulation. installed. Pipe ends are spanned with a unique sealing gasket, over which metal clamps are bolted, mechanically locking tltc pipes together and protecting the gasket. An ordinary small wrench is the only tool re- lieing built under the supervision of the United States Maritime Commission, in one week's time. Production in this quan Refrigerating Systems Use tity has enabled the company to meet the schedule requirements of the government. Pa^klcss Valves Victaulic pipe coupting The Henry Valve Company, Chicago, Stove Manufacturer Builds Lifeboats for Liberty Ships After being in the stove business more than 30 years, the Globe American Corpo ration, Kokomo, Ind.', was suddenly called upon to equip a considerable portion of its plant facilities to manufacture steel lifeboati of its own design which the United States supplies various types of incklcss valves for refrigeration systems on Lilicrty shijvs to the York Ice Machinery Cor|Kiration and to the Carrier Cor|toratiou. Strainers and dehydrators are also supplied to these companies. Through the firm of Gihhs and Cox. New York, the Henry Company furnished forged steel globe valecs for steam drain lines. quired for assembling the two bolts. Pre vious experience or skill is unnecessary. Each coupling permits several degrees of angular deflection which absorbs movement or straining of pipes in heavy seas. Eaclt coupling takes care of pipe contraction and exiunsion, allowing telescopic movement of pipe lengths and eliminating the need oi pi|te bends or expansion joints. In addition, each Victualic coupling provides the fea tures of a pipe union, permitting access within a line, repair, or replacement of a Edward Valves Widely Used l>i|*e section or fitting without disturbing The Edward Valve & Manufacturing Company, Inc..
