FAQ:“Our metal mesh basket strainers seem to be prone to corrosion. What can we do to extend their lifespan in harsh chemical environments?”

A:Mesh basket strainers are commonly used in industrial settings to filter out debris and contaminants from various fluids, including liquids and gases. However, they can be susceptible to corrosion in harsh chemical environments due to exposure to corrosive chemicals and high temperatures.

To extend the lifespan of metal mesh basket strainers in such conditions, Choosing the right material for your basket strainer is crucial. Stainless steel alloys, such as 316L or Hastelloy, are known for their excellent corrosion resistance properties. These materials are highly resistant to a wide range of corrosive chemicals and can withstand elevated temperatures.

Applying coatings or liners can provide an additional layer of protection against corrosion. Teflon (PTFE) coatings, for example, are effective at resisting many corrosive chemicals and can be applied to the metal mesh to extend its lifespan.

The second is Implement a maintenance schedule that includes routine inspections. Check for signs of corrosion, such as rust or pitting, and address them promptly. Cleaning the strainer regularly can also help remove corrosive deposits.

Then, maintain appropriate temperature levels within the system. Extremely high temperatures can accelerate corrosion processes. If possible, implement temperature control measures to keep the environment within a safe range.

Ensure that the basket strainer is made of materials that are compatible with the specific chemicals in your process. Consult chemical compatibility charts and experts to make informed material choices.

After that, properly size the basket strainer to match the required flow rate and velocity. Oversized strainers can lead to stagnant zones where corrosive chemicals accumulate, increasing the risk of corrosion.

Also consider adding sacrificial anodes or impressed current cathodic protection systems to the strainer. These devices can help mitigate corrosion by diverting corrosive attacks away from the strainer itself.

In some cases, the use of corrosion inhibitors in the fluid being filtered can be beneficial. These chemicals can help reduce the corrosive effects on the strainer’s metal mesh.

Ensure that the strainer is installed correctly, with proper gaskets and seals to prevent chemical leakage. Any leaks can lead to concentrated corrosive environments.

At length, implement a monitoring and testing program to assess the strainer’s condition over time. This may include corrosion rate measurements, ultrasonic testing, or other non-destructive evaluation methods.

In conclusion, extending the lifespan of metal mesh basket strainers in harsh chemical environments requires a combination of material selection, coatings, maintenance, and monitoring. By implementing these strategies, you can enhance the strainer’s durability and reliability while minimizing the risk of corrosion-related failures in your industrial processes.
