Welcome to the product page of Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer with over 20 years of experience since 1998. Our 304 Stainless Steel Cylindrical Welded Filter Tube with 0.5mm Slot Opening is engineered to deliver superior performance in water filtration applications. This product combines precision slot technology with durable welded construction, ensuring consistent filtration efficiency and long service life. Designed for demanding environments, it offers excellent corrosion resistance and mechanical strength, making it an ideal choice for industrial, municipal, and household water treatment systems.
The filter tube is manufactured using high-quality 304 stainless steel, which provides excellent resistance to rust and chemical attack. The cylindrical shape and welded joints ensure uniform structural integrity, while the 0.5mm slot opening is precisely machined to achieve precise particle retention. Each tube undergoes strict quality control to guarantee uniform slot width and clean edges, reducing clogging and maintaining stable flow rates. The product is available in various diameters, lengths, and end connections to meet specific system requirements.

| Slot Shape | Continuous slot, trapezoidal or rectangular |
| Surface Finish | Pickled, polished, or electropolished |
| End Connection | Threaded, flanged, or plain ends (optional) |
Key Features and Benefits:
- Excellent Corrosion Resistance: 304 stainless steel withstands agressive water conditions, including chlorinated water and mild chemicals, ensuring long-term durability.
- High Mechanical Strength: Welded construction and cylindrical design provide resistance to pressure and impact, suitable for deep well or high-flow systems.
- Precise Slot Opening: 0.5mm slot effectively filters out particles of 0.5mm and larger, reducing sediment and protecting downstream equipment.
- Low Pressure Drop: Optimized slot geometry and open area ratio maintain high flow rates while minimizing energy consumption.
- Easy Cleaning and Maintenance: Smooth surface and corrosion resistance allow simple backwashing or chemical cleaning, extending service intervals.
- Customizable Dimensions: Diameter, length, and end connections can be tailored to fit existing systems, reducing installation costs.
- Wide Application Range: Ideal for water filtration in irrigation, swimming pools, wastewater treatment, industrial process water, and residential well water systems.
The 0.5mm slot opening is particularly effective for removing coarse sand, gravel, and other suspended solids from water. Unlike wire mesh filters, the slotted tube design offers greater structural rigidity and can withstand higher pressure differentials. The welded joints are fully penetration welded, ensuring no weak points and eliminating the risk of slot deformation during operation. Each tube is hydrostatically tested (optional) to verify leak-tightness under pressure.
Technical Advantages:
- Manufactured using advanced CNC slotting machines for consistent slot width and edge quality.
- Heat treatment (optional) to relieve welding stress and improve dimensional stability.
- Available with protective end caps or packaging for safe transport.
- Compliance with international standards (e.g., ASTM A240) for material grade – verify with our team.

Frequently Asked Questions (FAQ)
A: 304 stainless steel can typically handle temperatures up to 800°C (1472°F) in oxidizing environments, but for water filtration, the ambient temperature is usually below 100°C. For high-temperature applications, please consult our technical team.
A: Yes, we offer slot openings from 0.1mm to 10mm. The 0.5mm is a standard option, but we can produce other sizes based on your filtration requirements. Minimum order quantities may apply for non-standard sizes.
A: The tube can be backwashed with clean water or cleaned using a mild acid solution (e.g., citric acid) for scale removal. Avoid using strong acids or chlorides that may damage the stainless steel surface. For heavy fouling, ultrasonic cleaning is also effective.
A: We offer threaded (NPT/BSPT), flanged (ANSI/DIN), and plain ends for welding. Custom connections are possible upon request. Please provide the connection type and size when ordering.
A: 304 stainless steel has good resistance to chloride-induced stress corrosion cracking in low chloride environments. For high chloride content (e.g., seawater), we recommend 316 stainless steel or higher-grade materials. Contact us for specific recommendations.
A: For standard sizes, lead time is 15-20 working days. Custom orders may require 25-30 working days, depending on complexity and quantity. We offer expedited shipping options for urgent needs.
A: Yes, we can provide samples (subject to shipping cost and sample fee). The sample fee is refundable upon bulk order placement. Sample dimensions can be customized to simulate your actual application.
A: We use CNC slotting machines with precision feedback systems. Each slot is measured using a laser micrometer during production, and final inspection is performed with go/no-go gauges to ensure tolerance within ±0.05mm.
