10. Professional FAQ for Basket Strainers & Y Strainer

Frequently Asked Technical Questions

Q: What materials are available for 2 basket strainer production?
A: The most popular materials include AISI 304/316/316L stainless steel for corrosive media, and ASTM A216 WCB carbon steel for general applications. Special options: Alloy 20, duplex SS for chloride-rich environments. All conform with ISO 15761 and ASTM/ASME norms.
Q: How to select the right basket mesh size?
A: Mesh size depends on the target particle size in your medium. Typical range: 40μm (fine particles, e.g., RO feed) to 2000μm (large, coarse debris). Finer meshes (100~200μm) often used for precision process or downstream equipment protection.
Q: Are there international standards for 2 inch basket strainer design?
A: Yes. Key standards: ASME B16.5/ANSI B16.34 for design and flange, EN1092-1 for EU, and ISO 9001 for QA. FDA/NSF apply for food-grade/sanitary usage.
Q: How often are baskets cleaned or replaced?
A: Frequency is a function of contamination level. For average service: 3~6 months cleaning, but high-load applications (wastewater) may require biweekly attention. Basket life expectancy: 2~4 years (SS), up to 6 months (carbon steel, corrosive use).
Q: What is the permissible maximum pressure?
A: Standard 2 basket strainer designs: rated PN16/ANSI 150. High-pressure variants available (PN25/ANSI 300) with reinforced wall/cover design. Burst tested at >2x rated pressure, complying with ISO 5208.
Q: Is installation orientation important?
A: Yes, always install with the flow arrow in direction of process media. Vertical or horizontal mounting allowed, but ensure basket is below centerline (to trap debris) and allow easy access for basket removal.
Q: What certificates are delivered with basket strainer products?
A: Each delivery includes material certificate (EN 10204 3.1), pressure test report, and Certificate of Conformity (ISO 9001, CE/ATEX if applicable).
