WETTING OIL TREATMENTSaturation of the surface layer of rusty and scaled steelwith wetting oil that is compatible with the priming paint,thus improving the adhesion and performance of thepaint system to be applied.

COLD PHOSPHATE SURFACE TREATMENT

Converting the surface of steel to insoluble salts ofphosphoric acid for the purpose of inhibiting corrosionand improving the adhesion and performance of paints tobe applied.

BASIC ZINC CHROMATE-VINYL BUTYRALWASHCOAT (Wash Primer)Pretreatment which reacts with the metal and at thesame time forms a protective vinyl film which contains aninhibitive pigment to help prevent rusting.

HOT PHOSPHATE SURFACE TREATMENTConverting the surface of steel to a heavy crystalline

layer of insoluble salts of phosphoric acid for the purposeof inhibiting corrosion and improving the adhesion andperformance of paints to be applied.

SELECTION OF CORROSION RESISTANT MATERIALSThe tabular information on the following pages is an attempt to present a summarized analysis of

existing test data. It is necessarily brief and, while the utmost precautions have been taken in itspreparation, it should not be considered as infallible or applicable under all conditions. Rather, it should

be looked upon as convenient tool for use in determining the degree of safety which various materials arecapable of providing and in narrowing down the field of investigation required for final selection. Thisparticularly applies where failure due to corrosion may produce a hazardous situation or result inexpensive down-time.

Footnotes have been generously used to explain and further clarify information contained in thistable. It is most important that these notes be carefully read when using the table.

In rating materials, the letter A has been used to indicate materials which are generallyrecognized as satisfactory for use under the conditions given. The letter F signifies materials which aresomewhat less desirable but which may be used where a low rate of corrosion is permissible or wherecost considerations justify the use of a less resistant material. Materials rated under the letter C may besatisfactory under certain conditions. Caution should be exercised in the use of materials in thisclassification unless specific information is available on the corroding medium and previous experiencejustifies their use for the service intended. The letter X has been used to indicate materials generally

recognized as not acceptable for the service.Information on metals has been obtained from the International Nickel Company, the Dow

Chemical Company, the Crane Company, the Haynes-Stellite Company, Corrosion Resistance of Metalsand Alloys by McKay & Worthington, Metals and Alloys Data Book by Samuel L. White, Chemical andMetallurgical Engineering and The Chemical Engineers Handbook, Third Edition by McGraw-Hill.

NOTESGACKET MATERIALSI. The general accepted temperature limit for a good grade compressed asbestos, also called

asbestos composition sheet, is 750oF. However, some grades are successfully used at

considerable higher temperatures. This type of sheet is used for smooth flanges. For roughflanges, gaskets cut from asbestos-metallic sheet or formed by folding asbestos-metallic clothare preferred. The latter, and gaskets cut from felted asbestos sheet, are indicated for flangeswhen bolt pressures are necessarily limited because of the type of flange material.

II. Data from the Pfaulder Company are given from the special point of view of suitability of thegasket material for use with glass-lined steel equipment.

III. Data in this column apply specifically to Silastic 181, a special silicon rubber for use ingasketing produced by Dow-Corning Corporation.

IV. Fiberglass fabric filled with Silastic silicone rubber (polusiloxane elastomer) has a usablecompressibility of about 20 percent and shows the chemical resistance cited here over thetemperature range from -85 to 392

oF. Both the silicone rubber and ordinary synthetic rubber


11/24

are available as gasket materials in which the reinforcing fabric is a metal cloth (brass,aluminum, iron, stainless steel). The chemical properties of these constructions are the sameas those given here for the Fiberglas-reinforced material, with the properties of the metal inthe cloth imposed upon them. The metal-cloth construction for increased mechanical strengthand electrical conductivity.

V. Teflon is the DuPont trade-name for polymerized tetrafluoreithylene. It is completely inert inpresence of all known chemicals. It is not affected by any known solvent or combinationsolvents. It is chemically stable up to 671

oF but, being a plastic, it is not recommended

gasket applications above 392oF or for high pressures unless confined in a tongue-and-

groove similar joint.
