CURE for CORROSION HEADACHES Specify Alcoa Aluminum for • Process Equipment • Transfer and Storage • Plant Structures Excessive maintenance and replacement of materials and equipment has fast become the biggest single headache in the process industries. Corrosion is far and away the most serious cause of such headaches. T h a t ' s the big reason why aluminum—Alcoa® Aluminum—is daily being specified and installed in an increasing variety of uses throughout the process industries. No other metal can match the ability of aluminum to resist successfully so many types of corrosive attack. And aluminum can be used to bring that unmatched corrosion resistance to a variety of appli cations . . . because only aluminum combines these other valuable properties in a single metal:
Light weight Good workability High thermal and electrical conductivity Great strength in alloys Nonmagnetic, nonsparking characteristics Nontoxicity Good reflectivity Clean, attractive appearance Low cost

heat exchanger tubes A 105,000 sq ft surface con denser with Alcoa aluminum heat exchanger tubes.
This brazed aluminum assembly, weighing nearly 900 pounds, is typical of exchangers used in air separation plants and other low-temperature exchange processes.
Aluminum heat exchanger tubes are low in cost, resist oxidation and other chemical attack, are easy to fabricate, have excellent thermal conductivity and freedom from embrittlement at low temperatures. Aluminum tubes have demonstrated their ability to give long, dependable service under severe conditions. They are used extensively in exchangers for handling hydrogen peroxide, nitric acid, hydrogen sulfide, ammonia, naval stores, glycerine, scrylonitrile and other chemicals. Alclad tubes are recommended for use with natural cooling waters. Aluminum costs approximately H the cost of admiralty, less than Yt> the cost of stainless, and in the common %" and 1" sizes, less than mild steel. Get detailed information on Alcoa aluminum heat exchanger tubes in booklet AD 186, available on request.
process piping Corrosion resistant Alcoa aluminum pipe is widely used to carry liquids and gases in chemical, petrochemical, petroleum and food processing plants. I t resists attack by the materials carried as well as by the corrosive atmosphere often encountered around such plants. And it prevents product contamination or discoloration. Aluminum pipe is available in all of the normally produced schedules. I t is by far the lowest priced corrosion resistant pipe available. For example, schedule 40 aluminum pipe is M the cost of schedule 5 stainless, 1 /7 the cost of schedule 40 stainless. Write for Aluminum Pipe and Fittings booklet, AD197.
Alcoa aluminum pipe proved ideal to solve corrosion and product contamination problems in this processing plant.
unitrace*
New type Unitrace section showing trace line cut back for joint. (Right) Special cast Unitrace flange for easy, efficient joining of new type Unitrace sections.
Alcoa now offers a new and improved design, of Unitrace, the unique aluminum steam-traced pipe which incorporates the steam line as an integral part of the pipe. Extruded as a single unit of aluminum, from Alcoa 3003-F alloy, Unitrace is available in diameters equal to 1H", 2", 3 " and 4 " pipe. Special cast Unitrace flanges and fittings are available in alloy A356-T6 for efficient joining of sections. In many installations, flanging is not required, as sections of Unitrace can be joined easily by welding. Preformed insulation will fit Unitrace al though thermal insulation is unnecessary in many cases. For detailed information, write for Bulletin AD418. •Registered trademark

World's largest all-aluminum tank stands 26 feet high,"has a diameter of 128 feet, holds 2Và million gallons of 8 3 % ammonium nitrate solution.
standard and special storage tanks Alcoa standard storage tanks, fabricated of 3003 alloy, are supplied in sizes ranging from 5,800 to 21,400 gallons. Both horizontal and vertical construction are available. Made from stocked components, these standard tanks bring the user all the advantages of Alcoa Aluminum at lower cost, with faster delivery. Storage tanks to meet many special requirements may be constructed of Alcoa sheet and plate. Information on design and fabrication will be furnished on request. Write for Alcoa Standard Storage Tanks Bulletin, AD387.
Alcoa Standard Tanks provide storage economies for a wide variety of chemicals.
shipping containers Alcoa offers a wide variety of shipping containers conforming to ICC regulations. Ranging in size from 7}^ to 110 gallons, they are used to ship such diverse products as beer and fuming nitric acid. Alcoa aluminum containers are lighter in weight than containers of other suitable materials, are less expensive and give longer service.
roofing, siding, structurais and paint Alcoa industrial building sheet is used for roofing and siding on plant buildings and to protect conveyors and other outdoor equipment. The aluminum surface requires practically no maintenance and lasts well even when exposed to corrosive atmospheres often encountered around processing areas. I t is easily installed and helps to keep construction costs low. Alcoa also supplies structural shapes for use in construction where their corrosion resistance and consequent low maintenance cost are advantageous. Paints pigmented with Alcoa Aluminum provide a continuous metallic sheet of pure aluminum for unmatched protective power. Write for Alcoa Industrial Building Products booklet, AD285, Alcoa Sandwich Walls booklet, AD625, or Painting With Aluminum booklet, AD228. Aluminum exterior surfaces for buildings and conveyors provide pleasing appearance with minimum maintenance.
