Twin disc check valve of rust-prone materials

What are the reasons for rusting of materials?

Dual plate wafer type check valves of CI (Cast Iron), DI (Ductile Iron), and WCB (Carbon Steel) materials, are subject to rust over time. Here are some common causes of rust and possible solutions:

CI (Cast Iron), DI (Ductile Iron), and WCB (Carbon Steel) materials can rust due to the following conditions
  • Humid Environment: Prolonged exposure to humid or rainy environments can cause the metal surface to react with moisture and oxygen, forming iron oxide (rust).
  • High Salinity Air: In coastal or salt-spray environments, the salt in the air accelerates the electrochemical corrosion of the metal.
  • Acidic Substances: Contact with acidic substances (such as acid rain or industrial pollutants) can speed up the corrosion process.
  • Industrial Pollution: Air in industrial areas contains various corrosive gases (like sulfur dioxide and hydrogen sulfide) that react with the metal surface, leading to corrosion.
  • Temperature Changes: Frequent temperature changes can cause condensation on the metal surface, increasing the risk of rust.
CF8, CF8M is more resistant to rust than other metals, it can still rust under certain conditions. Here are some factors that can cause stainless steel to rust
  • Mechanical Damage: Scratches or abrasions can damage the protective layer on the surface of stainless steel, exposing the underlying metal and increasing the risk of rust.
  • Chemical Corrosion: Exposure to strong acids, bases, or salts can accelerate the corrosion of stainless steel.
  • Electrochemical Corrosion: When stainless steel surfaces are contaminated with particles or dust from other metals, electrochemical reactions can occur in humid environments, damaging the protective layer.
  • Organic Substance Corrosion: Organic substances (like food residues) adhering to the surface of stainless steel can form organic acids in the presence of water, which can corrode the metal surface.
  • Air Pollution: In polluted air containing high levels of sulfur compounds, carbon oxides, and nitrogen oxides, condensation can form acidic liquids that cause chemical corrosion.

If you are concerned about valves rusting, we can provide solutions.
We can apply anti-rust oil to dual plate check valves and then seal them in plastic bags to slow down the rusting process.
Wrapping valves in a plastic bag can help delay rusting to some extent, as it reduces the metal's exposure to moisture and oxygen in the air. However, please note that method is not entirely effective if in humid or variable environments.
