... are discussed as well as some general conclusions. For example, benzoic acid inhibits coupled metals well but is ineffective on cast iron when uncoupled. In general, the organic acids provide little RA when titrated to a pH of 5.5, titration to a pH of 4.5 can result in precipitation of the acid. Trends...

... Cast iron columns were used extensively in building construction in the United States beginning in the early 1800s and continuing until about the year 1900, when cast iron was supplanted by structural steel. Many structures from this era still exist and are presently being restored or renovated...

... Immersion tests of various duration were performed on copper-based alloys,nickel-based alloys, cast irons, and stainless steels. Specimens were exposed at two upstate New York reservoirs as well as in a laboratory environment. The type of corrosion as well as the amount of corrosion varied...

.... Results of a 250-day test involving cast iron pipe sections are outlined. The test regime described provides a reliable method for the evaluation of the likely long term anaerobic corrosion behavior of any selected materials and associated corrosion protection methods. sulfate-reducing bacteria...

... protection to cast iron, an aluminium alloy, copper, brass and solder. Three types of test procedures involving high rates of metal-to-coolant heat transfer have been developed in which the effects of the composition, flow rate, pressure and temperature of the coolant and of the heat flux through the metal...

... elevated pressures, propylene glycol (PG) and methoxypropanol (MP) based coolants are shown to provide consistently more resistance to cavitation corrosion of cast iron than ethylene glycol (EG) based coolants. At slightly elevated pressures MP coolants may be superior to PG coolants. cavitation...

... Prior to 1960 most cast iron soil pipe joints were caulked with lead and oakum. Today the vast majority of such joints are sealed with rubber gaskets. Over 64 million such gaskets were used in the United States in 1972. Much of the success of these sealants can be attributed to the development...

... A description is given of problems arising during manufacture of standard reference material castings for the National Bureau of Standards. Cast iron, steel, blast furnace compositions, ductile iron, and high temperature alloys are discussed. Techniques to effect sound structure and integrity...
