As a leading manufacturer with over two decades of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Wedge Wire Filter 0.4mm Slot 316L SS, specifically engineered for rigorous petrochemical filtration applications. Our factory, established in 1998, has been a trusted supplier to global markets including North America, Europe, and the Middle East, delivering high-performance filtration solutions that meet the demanding requirements of oil, gas, and chemical processing. This filter combines precision slot sizing with robust 316L stainless steel construction, ensuring reliable separation of solids from liquids in corrosive and high-temperature environments. With a 2-year warranty, we stand behind the durability and performance of our product.
The Wedge Wire Filter features a continuous V-shaped wire wound around a support structure, forming a precise 0.4mm slot that allows efficient flow while preventing clogging. This design minimizes pressure drop and maximizes filtration surface area, making it ideal for catalyst recovery, fluid cracking, and other petrochemical processes. The 316L stainless steel material offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, even in chloride-rich environments. Below is a summary of key technical specifications:

Key Product Features & Benefits:
- Precision 0.4mm slot: Ensures consistent particle retention, reducing downtime for cleaning and improving product quality.
- 316L stainless steel construction: Exceptional corrosion resistance in petrochemical environments, extending service life and reducing replacement costs.
- Self-cleaning design: The V-shaped wedge wire profile prevents particles from lodging inside the slot, allowing backwashing to be highly effective.
- High mechanical strength: The robust support structure withstands high differential pressure and mechanical stress, typical in petrochemical reactors and separators.
- Customizable dimensions: Available in various diameters, lengths, and end connections to fit existing equipment without modification.
- 2-year warranty: Our confidence in manufacturing quality provides you with peace of mind and long-term reliability.
The wedge wire filter is widely used in petrochemical applications such as: crude oil desalting, gas sweetening, catalyst bed support, refinery waste water treatment, polymer filtration, and chemical intermediate processing. Its open area ratio (typically 30-60%) ensures high flow rates while maintaining filtration accuracy. The 0.4mm slot is particularly effective for removing fine particles without excessive pressure drop, which translates to energy savings for your pumping system.
We also offer optional surface treatments like electropolishing to further enhance corrosion resistance and reduce particle adhesion. All filters are manufactured under strict quality control procedures, including dimensional inspection and slot uniformity testing. Our production capacity supports both small trial orders and large-scale projects, with flexible lead times to meet your schedule.

Frequently Asked Questions (FAQ):
-
Q: What is the typical lifespan of a 316L wedge wire filter in petrochemical service?
A: The lifespan depends on operating conditions such as temperature, pressure, and chemical exposure. With proper maintenance, 316L filters can last several years in moderate environments. Our 2-year warranty covers manufacturing defects, and many customers report 5+ years of service. -
Q: Can the filter be cleaned and reused? How?
A: Yes, the wedge wire design is easily backwashable. You can clean it by reversing flow, using water or chemical cleaning agents, or by ultrasonic cleaning. The V-shaped slots prevent particle entrapment, making cleaning efficient. -
Q: Do you offer custom slot sizes? What is the tolerance?
A: Yes, we can custom manufacture filters with slot widths from 0.1 mm to 5 mm. Standard tolerance is ±0.05 mm for slots up to 1 mm, and ±0.1 mm for larger slots. Please provide your required slot size and we will confirm the feasibility. -
Q: What connecting methods are available?
A: We offer flanged ends (ANSI, DIN, JIS), threaded ends (NPT, BSP), and plain ends for welding. Custom adapters are also available. Please specify your connection requirement when ordering. -
Q: Is the filter suitable for high-temperature applications?
A: 316L stainless steel can withstand temperatures up to about 400°C (752°F) in continuous service, though oxidation resistance decreases above 800°C. For extreme temperatures, we can suggest alternative materials like Inconel or Hastelloy. -
Q: How do I determine the correct size for my application?
A: The appropriate diameter and length depend on flow rate, viscosity, particle loading, and allowable pressure drop. Our technical team can assist with sizing calculations based on your process parameters. Please contact us with your operating conditions. -
Q: What is the minimum order quantity (MOQ)?
A: For standard sizes, MOQ is 10 pieces. For custom sizes, MOQ may be 50 pieces or more depending on complexity. We also accept sample orders for testing purposes. -
Q: How long does delivery take?
A: For standard filters, delivery is typically 15-25 working days after order confirmation. Custom orders may require 30-40 working days. Expedited shipping is available upon request.
