Factors to Consider

Mostly, the wedge wire screen material selection based on your working environments. The operating environment conditions plays a crucial role in material selection ou should tell us as more as information you know to help you decide which material you should choose, and the operating environments may including the following aspects:

Temperature

Both the working temperature and media temperature should be taken into consideration.

Abrasion Resistance

Consider if the filter media contains abrasive particles and choose right material to withstand wear and erosion over time.

Chemical Compatibility

Determine if there is chemical corrosion and what type is it to choose the screen material compatible with the chemicals.

Strength and Durability

Depending on the application, choose material with required mechanical strength to withstand the loads and stresses it will encounter during operation.

Cost Considerations

Material costs can vary significantly, and it's essential to balance performance requirements with the available budget.

Commonly Used Material Grade

Several materials are commonly used for manufacturing wedge wire screens:

  • Stainless Steel: Stainless steel is one of the most popular materials for wedge wire screens due to its excellent corrosion resistance, strength, and durability. It is available in various grades (e.g., 304, 316, 316L) to suit different applications, but it is not suitable for extremely high-temperature environments. And the cost can be higher than some alternative materials.
  • Duplex Stainless Steel: Duplex stainless steels offer enhanced corrosion resistance and higher strength compared to austenitic stainless steel. They are often chosen for applications where extreme corrosion resistance is required. But the cost is higher than standard stainless steel and it require specialized welding procedure.
  • Inconel alloy (e.g. Inconel 600, Inconel 625): Inconel alloys are known for their high-temperature resistance and excellent mechanical properties. They are suitable for applications involving elevated temperatures. But the cost is high and it requires specialized machining and welding techniques.
  • Hastelloy (e.g. Hastelloy C-276): Hastelloy alloys are superior resistance to a wide range of corrosive chemicals that excel in harsh chemical environments. They are commonly used in chemical and petrochemical industries. But the cost is high and it requires specialized machining and welding techniques.
  • Nickel Alloys (e.g. Monel 400) Monel alloys exhibit strong resistance to corrosion by acids and alkaline solutions. They are frequently used in marine and chemical processing applications. But it is not as corrosion-resistant as some other alloys in high aggressive chemical environments.
  • Other Exotic Alloys: Depending on specific requirements, other exotic alloys such as titanium or nickel can be considered for specialized applications.
