How to Choose a Suitable Wedge Wire Screen?
In the oil, mining, water treatment and other industries, wedge wire screens are precision filters that ensure smooth operation of the system. Improper selection may lead to blockage, sanding, corrosion perforation and even structural failure. Master the following three core dimensions to help you select accurately:
Step 1: Match the gap accuracy - "block" and "flow smoothly"
Core parameters: V-wire gap width-determines the filtration accuracy and smoothness.
Step 2: Choose the right material-resist corrosion and extend life
- Core considerations: medium composition, temperature, chlorine concentration, pH value.
- Mainstream materials and applicable scenarios:
- 304 stainless steel: economical choice, suitable for general fresh water and neutral environment.
- 316L stainless steel: the first choice for chloride ion environments, such as seawater, brine, and oilfield reinjection water, significantly improves pitting resistance and extends life.
- Duplex stainless steel (such as 2205): withstands strong corrosion and high stress environments (such as acid mine drainage and high-pressure deep wells).
Step 3: Ensure structural strength - pressure resistance without collapse
- Core elements: support rib design to resist external formation pressure or internal negative pressure.
- Key to strength:
- Material and thickness of support bars: need to be selected based on the screen diameter and expected maximum working pressure. Deep well and high pressure environment have higher requirements.
- Manufacturing process: The fully welded structure ensures that the ribs are firmly connected to the base pipe.
- Clearly define the working conditions (medium, pressure, temperature, corrosiveness), trust professional analysis, and focus on long-term value, not just unit price.
