Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of precision filtration components since 1998. Our Precision Welded Stainless Steel Candle Filter Element Skeleton, crafted from high-grade 316 SS, is designed to deliver exceptional durability and reliable performance in demanding industrial applications. With a 100-micron mesh and 2-inch threaded connection, this filter element offers a balance of fine filtration and robust structural integrity, making it ideal for petrochemical, pharmaceutical, and water treatment systems.
Each candle filter skeleton is produced using advanced welding techniques to ensure consistent pore distribution and seamless joints, eliminating weak points and extending service life. The 316 stainless steel material provides excellent corrosion resistance against aggressive chemicals and high-temperature fluids, while the 100-micron rating effectively captures particulate without compromising flow rates. The 2-inch threaded connection simplifies installation and replacement, reducing downtime during maintenance.
Key Features & Benefits
- Superior Material: 316 stainless steel resists pitting, crevice corrosion, and oxidation, ensuring long-term performance in harsh environments.
- Precision Welded Construction: Automated welding process guarantees uniform mesh openings and strong joints, preventing media bypass and mechanical failure.
- High Filtration Efficiency: 100-micron (150 mesh) rating suitable for fine particle removal, with differential pressure capabilities up to 0.5 MPa (optional customization).
- Easy Installation: Standard 2-inch NPT/BSP threaded connection fits common piping systems; adapter options available for other thread sizes.
- Customizable Design: Available in various lengths (from 10" to 60") and end cap configurations (open, closed, with or without gasket seat).
- Low Maintenance: Robust skeleton withstands backwashing and chemical cleaning, reducing replacement frequency.

The precision-welded skeleton ensures that the mesh is securely bonded to the support structure, minimizing the risk of mesh detachment under high flow or pressure pulses. This design is particularly beneficial for applications requiring frequent backwashing, such as in catalyst recovery or polymer filtration. Our 100-micron mesh is woven from 316 stainless steel wire with consistent opening sizes, guaranteeing reliable particle retention and easy cleaning.
Applications
- Petrochemical and refining (gas oil, aromatic solvents)
- Pharmaceutical and biotech (fermentation, sterile filtration)
- Water and wastewater treatment (pre-filtration, membrane protection)
- Food and beverage (syrup, beer, wine clarification)
- Chemical processing (acid, alkaline, and solvent filtration)

Frequently Asked Questions
Q1: What is the difference between a candle filter element and a cartridge filter?
A1: A candle filter element typically has a cylindrical shape with a rigid, welded skeleton that supports the filter media, making it more durable for high-pressure applications. Cartridge filters often use folded media and are enclosed in a housing. Our candle filter skeletons are designed for easy cleaning and repeated use.
Q2: Can this filter be used for high-temperature applications?
A2: Yes, the 316 stainless steel skeleton can withstand temperatures up to 450°C, provided the gasket or sealing material is compatible. For extreme temperatures, we recommend high-temperature silicone or metal gaskets.
Q3: Is the 100-micron rating suitable for water filtration?
A3: Absolutely. 100 micron (approx. 150 mesh) is effective for removing sand, rust, and other suspended solids from water. It is commonly used as a pre-filter for reverse osmosis systems or as a final filter for irrigation.
Q4: What thread standards are available for the 2-inch connection?
A4: We offer both NPT (American) and BSP (British) threads. Please specify your requirement when ordering. Adapters for other thread types can also be provided.
Q5: How do I clean a welded stainless steel filter skeleton?
A5: Cleaning methods include backwashing with clean water or solvent, ultrasonic cleaning, and chemical soaking. The welded structure is robust enough to withstand repeated cleaning cycles without deformation.
Q6: Can you customize the length or end cap design?
A6: Yes, we offer custom lengths from 10 to 60 inches and various end cap options (open, closed, with or without O-ring groove, etc.). Please provide your drawing or specifications for a tailored solution.
Q7: What is the typical lead time for this product?
A7: Standard sizes are usually shipped within 15–20 working days. Custom orders may require 25–30 days depending on complexity. We can expedite for urgent projects.
Q8: Do you offer samples for testing?
A8: Yes, sample orders are welcome. Please contact our sales team with your requirements. Sample cost and shipping will be quoted.
