Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer established in 1998 with an annual export value of US$5–10 million. We specialize in producing high-precision filtration components, and our Automatic Laser Welded Cylindrical Filter Tube (2m length, 0.2mm slot width) is designed to deliver superior performance in oil filtration applications. Engineered for durability and efficiency, this filter tube combines advanced laser welding technology with robust stainless steel construction, ensuring consistent filtration and long service life even in demanding industrial environments.
Our filter tubes are manufactured using fully automatic laser welding equipment, which guarantees uniform slot width, minimal heat-affected zones, and excellent mechanical strength. The 0.2mm slot width is precisely controlled to capture fine particles while maintaining high flow rates, making it ideal for filtering lubricating oils, hydraulic oils, and process fluids. Whether you need a standard 2-meter length or customized dimensions, we offer flexible solutions to meet your specific filtration requirements.
Product Features & Technical Specifications
- Automatic Laser Welding – Ensures precise slot width (±0.02mm tolerance) and smooth weld seams, eliminating weak points and reducing the risk of leakage.
- High-Strength Stainless Steel – Made of premium 304 or 316L stainless steel (optional), offering excellent corrosion resistance and mechanical strength for harsh oil environments.
- 0.2mm Uniform Slot Width – Provides reliable filtration of particles down to 200 microns, suitable for coarse and medium filtration stages in oil systems.
- 2-Meter Standard Length – Reduces the number of joints required in long filtration lines, simplifying installation and maintenance. Custom lengths available upon request.
- Cylindrical Design – Maximizes surface area for high dirt-holding capacity and allows easy backwashing or cleaning.
- Optional End Connections – Available with flanged, threaded, or plain ends to fit various equipment and piping configurations.
- Surface Finish Options – Pickled, polished, or oil-removed surfaces to suit different cleanliness requirements.

Frequently Asked Questions (FAQ)
-
Q: What materials are used for the filter tube?
A: We mainly use 304 and 316L stainless steel. 316L is recommended for highly corrosive oil environments or when resistance to chloride stress corrosion is required. Please advise your specific conditions. -
Q: Can the slot width be customized to other sizes?
A: Yes, we can produce slot widths from 0.1mm to 3mm according to your filtration requirements. The 0.2mm slot width is our standard for oil filtration, but we are happy to adjust. -
Q: What is the maximum operating pressure for this filter tube?
A: The pressure rating depends on the diameter, wall thickness, and end connections. Typically, our tubes can withstand pressures up to 20 bar (300 psi) for standard configurations. For higher pressures, we can reinforce the design. -
Q: How do I clean the filter tube?
A: The tube can be cleaned by backwashing, ultrasonic cleaning, or chemical cleaning (depending on the contaminant). The laser-welded structure is robust enough to withstand repeated cleaning cycles. -
Q: Do you provide samples for testing?
A: Yes, we offer sample tubes (usually 300mm length) for qualification. Please contact our sales team to discuss sampling procedures and shipping costs. -
Q: What is the typical lead time for a standard order?
A: For standard 2m length tubes with 0.2mm slot width, lead time is approximately 15–20 working days after order confirmation. Custom specifications may require 25–30 working days. -
Q: How do you ensure the slot width consistency?
A: Our automatic laser welding machine is equipped with real-time monitoring and feedback control, and we perform 100% inspection of slot width using optical measurement tools. Each tube is tested before shipment. -
Q: Can I order non-standard lengths or diameters?
A: Absolutely. We can produce lengths up to 6m (single piece) and diameters from 50mm to 200mm. For larger diameters, please consult our engineering team for feasibility.
