Sep 25 2002The chemical resistance of the anodized layer can be quite good depending on several factors The anodic layer is aluminum oxide (Al 2 O 3) so it is quite resistant to attack by most substances However the typical anodizing processes result in a somewhat porous coating which allows easier migration of the corrosive substances to the aluminum surface
possible to get an idea of the chemical resistance based on the type of chemical product Based on its structure you can classify the reagent into one of the chemical groups figuring in Table II on page 25: aldehydes ketones inorganic acids Of course to do so some chemistry knowledge is required

CHEMICAL RESISTANCE GUIDE The information is provided ONLY as a guide to assist in determining chemical compatibility for wetted components Testing under the specific conditions of the application is recommended Stenner Pump Company assumes no responsibility for its accuracy Outside factors
CHEMICAL RESISTANCE DATA These recommendations are based upon information from material suppliers and careful examination of available published information and are believed to be accurate However since the resistance of metals plastics and elastomers can be affected by concentration temperature presence of other chemicals and other factors
Derakane Chemical Resistance Guide English In the chemical resistance tables a blank space simply indicates that no data was available at the time that temperature ratings were assigned NR stands for "not recommended" at any temperature LS stands for "limited service" (at least 3 days to 1 year at maximum 40C/100F)
The petroleum and chemical industries contain a wide variety of corrosive environments many of which are unique to these industries Oil and gas production operations consume a tremendous amount of iron and steel pipe tubing pumps valves and sucker rods Metallic corrosion is costly However the cost of corrosion is not just financial Beyond the huge direct outlay of funds to repair or
