Corrosion Protection of Metal and Plastic Valves (
Valve corrosion refers to the degradation of metal components due to chemical or electrochemical reactions with their environment. This process is natural, as metals tend to interact with surrounding elements, leading to damage over time. To mitigate this, one common approach is to isolate the metal from its surroundings or replace it with non-metallic synthetic materials. Corrosion significantly affects a valve’s lifespan, reliability, and overall performance. When mechanical stress and corrosive factors act together, they accelerate surface wear, which is particularly critical in valve operations where friction and environmental exposure are constant.
In harsh environments, such as those found in oil, natural gas, and formation water pipelines, the presence of substances like hydrogen sulfide, carbon dioxide, and organic acids can severely degrade metal surfaces, reducing their functionality. The extent of chemical corrosion depends on various factors, including temperature, mechanical load, lubricant composition, acid resistance, contact duration with the medium, and the catalytic effect of the metal during nitriding processes. These variables influence how quickly corrosion occurs and how effectively protective measures can be applied.
To combat corrosion, several methods are employed for metal valves. One approach is applying protective coatings, such as paints, pigments, or lubricants, to shield the valve throughout its lifecycle—whether during manufacturing, storage, transportation, or operation. The choice of method depends on the required protection duration, storage conditions, valve design, and cost-effectiveness. Common techniques include using volatile corrosion inhibitors, water- or alcohol-based solutions, applying protective films, and using thin polymer coatings. Many manufacturers currently use lubricants and water-resistant materials for corrosion prevention.
Synthetic materials have also gained popularity in valve applications due to their superior corrosion resistance, lighter weight, and customizable strength based on fiber reinforcement. While their tensile strength may be lower than that of metals, synthetic valves offer advantages in corrosive environments. They are often made from thermoplastics like PVC, PVDF, PPS, or thermosetting resins such as polyester, epoxy, and vinyl ester. Thermosetting resins generally exhibit better heat resistance, making them suitable for high-temperature applications.
In practice, synthetic valves reinforced with glass or graphite fibers are widely used in chemical processing. These materials combine strength, durability, and chemical resistance, offering an economical alternative to traditional metal valves. Their thermal expansion properties and resistance to deformation make them ideal for long-term use in aggressive environments.
Beyond traditional materials, the valve industry now incorporates advanced options such as ceramics (capable of withstanding extreme temperatures), plastics (with excellent corrosion resistance), and even memory alloys that leverage elasticity and shape recovery for specialized valve designs. These innovations are driving the development of high-performance valves tailored for demanding industrial applications. As new technologies emerge, the range of materials available for valve manufacturing continues to expand, opening up new possibilities for improved efficiency and longevity.
