As a trusted manufacturer with over 25 years of experience in wire mesh and filtration products, Anping County Boli Hardware Wiremesh Products Factory is proud to present our Nylon Screen Strainer 120 Micron, DN40 Flange, 316 Stainless Steel, 20 Bar Operating Pressure. This high-performance strainer is engineered to provide reliable and efficient filtration in demanding industrial applications. Our factory, established in 1998, combines advanced manufacturing techniques with rigorous quality control to deliver products that meet the highest standards of durability and performance. Whether you are filtering water, chemicals, or hydrocarbons, this strainer offers a robust solution that protects downstream equipment and ensures process continuity.
The 316 stainless steel body provides exceptional corrosion resistance and mechanical strength, suitable for both marine and aggressive chemical environments. The DN40 flange connection conforms to international standards (ISO 7005 / EN 1092), allowing easy installation into existing pipeline systems. With a nylon screen mesh of 120 microns, it effectively removes particles of 125 μm and larger, balancing flow rate and filtration efficiency. The 20 bar working pressure rating ensures safe operation under high-pressure conditions, making it ideal for industrial, agricultural, and municipal applications.
Key Features & Technical Specifications
- Body Material: 316 Stainless Steel (CF8M) – excellent resistance to chlorides, acids, and high temperatures.
- Screen Material: High-quality Nylon (PA66) – non-corrosive, lightweight, and easy to clean.
- Mesh Size: 120 micron (125 μm) – suitable for fine filtration of solids from liquids or gases.
- Connection: DN40 Flange (1.5" nominal) – drilled to standard PN16/PN20 patterns, available with raised face.
- Pressure Rating: 20 bar (290 psi) at ambient temperature; derated at higher temperatures.
- Temperature Range: -20°C to 80°C (-4°F to 176°F) for continuous use.
- Design: Y-type strainer configuration minimizes pressure drop and allows easy screen removal.
- Screen Retention: Secure clamping mechanism prevents bypass and ensures tight sealing.

Frequently Asked Questions (FAQ)
-
Q: What is the exact filtration rating of the nylon screen?
A: The screen is 120 micron, which corresponds to a nominal particle retention of 125 μm. It effectively removes particles of that size and larger. -
Q: Can the nylon screen be replaced or cleaned?
A: Yes, the nylon screen is removable and can be cleaned with water or a mild solvent. It is reusable. Replacement screens are available separately. -
Q: What flange standard does the DN40 connection comply with?
A: The flange is drilled to ISO 7005 / EN 1092 standard, compatible with PN16 and PN20 flanges. Custom drilling patterns (e.g., ANSI, JIS) are available upon request. -
Q: Is the strainer suitable for hot water or steam?
A: The maximum continuous operating temperature for the nylon screen is 80°C. For higher temperatures, we recommend a stainless steel mesh screen. Please consult us for options. -
Q: What is the pressure drop across the strainer at rated flow?
A: The pressure drop depends on flow rate and fluid viscosity. Typically, for water at 20°C, the pressure drop is less than 0.5 bar at nominal flow. Detailed data can be provided upon request. -
Q: Do you offer any certifications for the material?
A: We can provide material test certificates (MTC) for the 316 stainless steel body and calibration certificates for the mesh if required. Please specify your needs when ordering. -
Q: Can the strainer be used for corrosive chemicals?
A: The 316 stainless steel body is suitable for many chemical environments. However, the nylon screen may degrade in strong acids or oxidizing agents. For chemical compatibility, please consult our technical team. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard strainers is 10 pieces. For custom orders, MOQ may vary. Contact us for details.
