Air System Equipment i' Sheet Metal and Tubular Products Jones & Laughlin Steel Corporation Jones & Laughlin Building, Pittsburgh 30, Pa. WELDED and SEAMLESS STEEL TUBULAR PRODUCTS J & L Welded Pipe Jones & Laughlin manufactures Standard Weight, Extra Strong, and Double Extra Strong Welded Pipe, Black and Galvanized, for steam, gas, air, water, refrigeration and sprinkler work. Sizes: H in. to 10 in. inclusive. Jones & Laughlin Steel Pipe is made of soft, weldable steel rolled from solid ingots made to a special analysis. The steel pipe produced is soft and ductile, free cutting, strong at the welds, and free from excess scale. J & L Pipe is commercially straight and free from blisters, cracks or other injurious defects. Careful attention is given the threading of the pipe with good clean-cut threads fitted with sound couplings correctly tap ped to give a tight joint. Soft, ductile steel of free cutting quality enables the con tractor to cut clean, sound threads on the job. The Jones & Laughlin process of gal vanizing assures a thorough coating and insures against pipe being clogged with spelter. The galvanized coating adheres strongly and does not tend to flake off. J & L Seamless Pipe J & L Seamless Pipe is made in three weights; standard and extra strong in sizes 34 in. nominal to 14 in. O. D. inclusive, and double extra strong in sizes 2 in. to 8 in. inclusive. J & L Seamless Steel Pipe is pierced from a solid billet--there are no -welds. The result is dependable and uniform wall strength. The method of manufacture, and the use of only specially selected steel, assure exceptional ductility, a quality that is essential to successful coiling and bend ing, and flanging for Van Stone joints. J & L Seamless Pipe can be used with full satisfaction in either threaded joint or completely welded installations. Ductility, strength and safety--make this product especially adaptable for air, steam, gas and gasoline lines, boilers, refineries, dry kilns, refriger ating systems and other exacting applications. J & L Hot Rolled Seamless Steel Boiler Tubes J & L Seamless Boiler Tubes are manu factured in accordance with the ,4.S.Af.. Boiler Code and comply with the A.S.T.M. Specifications and the rules and regulations of the Bureau of Marine Inspection and Navigation of the U. S. Department of Commerce. They are- supplied in a full range of standard sizes, from 134 in. O.D. to 6 in. O.D. inclusive. The process by which Jones & Laughlin manufactures seamless boiler tubes is largely responsible for the unusually high ductility of the product. It is a process in which a forging action is predominant, and produces a desirable combination of strength with a highly ductile nature. J & L tubes therefore are installed with ease and safety. Other J & L Tubular Products J & L also manufactures Reamed and Drifted Pipe in sizes 1 in. to 12 in. inclusive. Dry Kiln Pipe, Pipe for Refrigeration Service, Water Well and Irrigation Casing, Line Pipe and a complete line of Oil Country Tubular Products in welded and seamless. Handbook on Standard Pipe Available without charge or obligation, to heating and piping contractors and heating and ventilating engineers, is the J & L tubular products handbook SP5. In addition to containing catalog information of J & L Standard Pipe this book includeshelpful engineering design data for con tractors and engineers. Write on your letterhead for a copy of this convenient handbook. 986 Air System Equipment sheet Meteis United States Steel Corporation Subsidiaries Carnegie-Illinois Steel Corporation, Pittsburgh and Chicago Columbia Steel Company, San Francisco Tennessee Coal, Iron & Railroad Company, Birmingham United States Steel Export Company, New York District Offices in ail Principal Cities USS COPPER STEEL For Superior Rust Resistance at Low Cost Corrosion resistance and cost are two determining factors of the type of metal to be used for various air conditioning jobs. Copper Steel has 2 to 3 times the atmos pheric corrosion resistance of plain steel or pure iron as shown in the results of un biased tests made at Pittsburgh, Ft. Sheridan and Annapolis by the American Society for Testing Metals. The cost of U'S S Copper Steel is less than that of pure iron or copper-bearing pure iron and only slightly more than plain steel. Thus there often is a dividend of 200 per cent to 300 per cent longer life and a saving in the first cost as well. When galvanized, U'S'S Copper Steel produces a sheet that is rust resistant all the way through--not just on the surface. It should be used for all ducts carrying humidified air or placed in damp locations such as basements, shower rooms, etc. USS PAINTBOND U S S Paintbond should be used whenever galvanized steel is to be painted. This special Bonderized sheet can be painted immediately, offers a much better surface for painting, lessens danger of the paint flaking and retards corrosion. It is used for ductwork, furnace housings and outdoor metal work. Send for our Paintbond booklet. USS DUL-KOTE U'S-S Dul-Kote is a specially treated non-spangled galvanized sheet which also can be painted immediately without ageing or otherwise preparing the surface. It is available in the South and in the West. Send for our Dul-Kote booklet. HERE'S THE PROOF! UNCOATED COPPER STEEL 91% SOUND AFTER 21 YRS. Corrosion test of AS.T.M. on 22 gage black sheets exposed at Annapolis, Md., October, 1916, The copper steel sheets outlasted all others in the test. OTHER U S-S PRODUCTS INCLUDE: Black Sheets--All grades, hot rolled, cold rolled in a number of different finishes. Stainless--Heat resisting steel for various uses where temperatures are high and corrosion severe. Cor-Ten--High strength steel--greater strength, greater atmospheric corrosion resistance for smokestacks, hoods, etc. For more information on U'S'S Galvanized, Copper, Black and Stain less Sheets, send for our Guide for Sheet Metal Workers. 987
