Benefits for Your Operation: By using our slot separator scraper filter screen, you achieve consistent particle removal, reduced pressure drop, and lower maintenance costs. The 304SS material resists corrosion from sour gas, brine, and chemicals commonly found in oil & gas streams. The precise slot geometry minimizes blinding and ensures efficient dewatering, helping you meet environmental discharge standards or improve product quality. Our screens are also compatible with automated scraper systems, making them ideal for continuous filtration processes.
With over 25 years of manufacturing experience, Anping Boli has supplied thousands of filter screens to global clients in the oil & gas, petrochemical, and water treatment industries. Our factory operates with advanced CNC wire winding machines and strict quality control procedures. We are capable of handling large-volume orders while maintaining short lead times. Our annual export value of US$5-10 million testifies to our reliability and international reach. We ship from multiple ports (Tianjin, Qingdao, Shanghai, Foshan) to destinations worldwide, including North America, Europe, Southeast Asia, and the Middle East.
Why Choose Boli? We offer not only standard products but also custom solutions based on your specific slot size, length, and end connections. Samples are available for testing before mass production. Our team provides prompt technical support and after-sales service. Contact us today to discuss your particle removal and dewatering requirements—we are confident in delivering a screen that exceeds your expectations.
Frequently Asked Questions
Q1: What is the difference between a Johnson screen and a standard wire mesh screen?
A: Johnson screens use a continuous V-shaped wedge wire wound around support rods, providing greater strength, larger open area, and a non-clogging slot profile. Standard wire mesh has lower structural integrity and is more prone to blinding.
Q2: Can this screen be used for sand control in oil wells?
A: Yes, our slot separator scraper filter screen is commonly used for sand control in oil and gas wells. The precise slot width filters out formation sand while allowing fluid flow.
Q3: Is 304 stainless steel suitable for sour gas environments?
A: 304SS offers good corrosion resistance in many environments. However, for high H2S concentrations, we recommend 316L or duplex stainless steel. Please contact us for material selection advice.
Q4: What is the maximum operating pressure for this screen?
A: The pressure rating depends on the screen diameter, wall thickness, and support structure. Typically, our screens withstand up to 10 MPa (1450 psi) for standard designs. Custom reinforcements can be made for higher pressures.
Q5: How do I clean the screen if it gets clogged?
A: The V-shaped slot design allows easy backwashing. In scraper filter systems, a rotating scraper continuously cleans the surface. For manual cleaning, high-pressure water or chemical cleaning can be used.
Q6: Do you offer samples for testing?
A: Yes, we provide samples (usually 300mm length) for evaluation. The sample cost and shipping are negotiable. Mass production samples can be arranged after order confirmation.
Q7: What is the typical lead time for a custom order?
A: For standard sizes, lead time is 7-15 days. For fully customized screens (special diameter, length, or connections), lead time is 15-25 days, depending on quantity.
Q8: Can you provide a certificate of material compliance?
A: Yes, we can issue a mill test certificate for the 304SS material upon request. Please specify when placing your order.
