It’s common for high performance filter housing components to experience some form of corrosion regardless of what type of metal is being used. Corrosion resistant coatings can increase the lifespan of a part, as well as reduce maintenance and replacement costs. In order to select the appropriate metals to extend the life of the housing, it’s important to identify what kind of corrosion a part is prone to. Based on how a part is used and what conditions it’s exposed to, the kind of corrosion that develops may differ.
General corrosion occurs as a result of rust. When metal, specifically steel, is exposed to water, the surface is oxidized and a thin layer of rust appears. In order to prevent oxidation, a preventative coating must interfere with the reaction. As an alternative to using metals that must be protected by layers of coatings, engineers often have an option to use different metal alloys that are selected for having a greater resistance to corrosion caused by its surroundings. As the saying goes “you get what you pay for,” so better corrosion resistance usually comes at a higher materials and manufacturing cost. Engineers must take into account that the corrosion resistance of any alloy depends on both the medium and the working conditions. Alloys with good resistance in one environment may have poor resistance in another, and their resistance is also likely to vary according to differences in exposure conditions, such as temperature, stress from high pressure, friction or vibration. Our filtration specialists at Filter Pure take in to consideration every working aspect of the water or liquid filtration application that they face. We have at our disposal the answers to the many methods for preventing or reducing corrosion. Most of the solution methods are orientated in one way or another toward slowing, reducing or eliminating the rate of corrosion on the metal filtration housings and parts.
