Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998, proudly presents our Cylindrical Welded Screen Tube 316L 0.5mm Slot 12m Length — a premium filtration solution engineered for the demanding petrochemical industry. With over two decades of expertise and annual export value exceeding US$5 million, we deliver precision-crafted screens that ensure consistent performance in harsh environments. This product combines high-strength 316L stainless steel with advanced wedge-wire welding technology to provide reliable solid-liquid separation, reducing downtime and maintenance costs for your operations.
Key Features & Technical Specifications
- Material Excellence: Made from 316L stainless steel, offering superior corrosion resistance against acidic, alkaline, and high-temperature fluids commonly found in petrochemical processes.
- Precision Slot Width: 0.5mm (0.0197 inches) slot opening ensures accurate particle retention, with a tolerance of ±0.03mm to maintain filtration efficiency.
- Welded Wedge Wire Construction: Continuous spiral winding with strong resistance welding creates a robust, uniform slot structure that resists clogging and deformation under high pressure.
- Long Length: Standard 12-meter (39.4 feet) tube reduces the number of joints required, minimizing leakage risks and simplifying installation in long filtration vessels.
- Customizable Parameters: Diameter, end connections (threaded, flanged, or plain), and surface finish can be tailored to your specific system requirements.
- High Open Area: Wedge wire design provides up to 60% open area, maximizing flow capacity while maintaining high filtration precision.

Advantages for Petrochemical Filtration
- Enhanced Durability: The welded construction eliminates weak points, ensuring the tube withstands high differential pressure and backwashing cycles without failure.
- Non-Clogging Design: The wedge wire profile allows particles to slide off the slot surface, preventing blinding and reducing cleaning frequency.
- Consistent Flow: Uniform slot spacing guarantees stable filtration efficiency across the entire tube length, even in viscous or high-solids fluids.
- Cost-Effective: Long 12m tubes reduce the need for multiple connections, lowering installation labor and potential leak points.
- Corrosion Resistance: 316L grade offers excellent resistance to chlorides, sulfides, and other corrosive agents present in petrochemical streams.
Typical applications include catalyst recovery, crude oil desalting, amine filtration, produced water treatment, and polymer filtration. Our screens are also used in sand control for oil and gas wells, as well as in chemical processing vessels requiring fine particle separation.

Frequently Asked Questions
-
What is the difference between 316L and 304 stainless steel for this screen tube?
316L contains molybdenum, providing superior resistance to pitting and crevice corrosion in chloride-rich environments, making it more suitable for petrochemical applications where aggressive chemicals are present. -
Can the slot width be customized to other sizes?
Yes, we offer slot widths ranging from 0.1mm to 6mm. Custom slot sizes are available upon request with reasonable lead times. -
How is the tube connected to the filtration system?
We provide various end connections: threaded (NPT/BSP), flanged (ANSI/DIN), or plain ends for welding. You can specify your preferred connection type. -
Is the tube suitable for high-temperature service?
316L stainless steel can withstand continuous operating temperatures up to 400°C (752°F) in oxidizing environments. For higher temperatures, other materials may be recommended. -
What is the maximum pressure rating for this screen tube?
The pressure rating depends on the tube diameter, wall thickness, and end connections. Please provide your operating parameters so we can recommend a design that meets your needs. -
How do you ensure the slot accuracy during production?
We use precision winding machines and laser measurement tools to control slot width within ±0.03mm tolerance. Each tube is inspected before shipment. -
Can I get a sample before placing a bulk order?
Yes, sample orders are welcome. We can produce a short section (e.g., 1m) with your specified slot and diameter for evaluation. -
What is the typical lead time for a 12m tube?
Standard lead time is 15–20 working days after order confirmation, depending on quantity and customization requirements. Faster delivery can be arranged for urgent projects.
