DN125 Flanged Industrial Basket Strainer: High-Flow Precision Filtration Solution

I. Product Overview

TIANYU DN125 flanged industrial basket strainers are precision filtration devices constructed from SUS304/SUS316 stainless steel, achieving 80-micron solid-liquid separation via a basket structure. Flanged connections ensure compatibility with industrial pipeline systems, while the design withstands -196℃~400℃ temperatures and PN0.6-1.0MPa pressures. Ideal for treating waste oil, water, chemical solutions, and more, these strainers excel in high-flow filtration scenarios.

Product Overview

III. Structural Design & Technical Features

Residue-Free Basket Structure
- Tapered bottom design (slope ≥30°) eliminates flow dead zones, with residue ≤0.5% of housing volume—suitable for food-grade (FDA certified) and pharmaceutical (cGMP compliant) applications.
- Embedded basket sealing with rubber O-rings ensures leakage rate ≤0.1L/h at 0.6MPa.
Mirror Polishing Technology
- Internal housing surface roughness Ra≤0.8μm, basket surface Ra≤0.4μm, reducing media adhesion and microbial growth to meet 3-A sanitary standards (dairy industry compatible).
Maintenance-Friendly Design
- Quick-opening top flange allows disassembly in ≤5 minutes, with basket removable for direct cleaning—extending maintenance cycles 2-3x compared to Y-type strainers.
- Optional pressure gauge ports (radial/axial) monitor differential pressure for timely basket replacement indication.

IV. Manufacturing Processes & Quality Control

Core Fabrication Steps
- Housing Forming: CNC plate rolling ensures diameter deviation ≤±1mm. TIG inert gas welding eliminates porosity/slag, verified by 100% penetrant testing (PT).
- Basket Processing: 316 stainless steel wire mesh undergoes high-temperature setting (850℃ annealing), with tensile strength ≥520MPa and mesh opening accuracy error ≤±5 microns.
- Surface Treatment: Electro-polishing creates passivation film ≥5μm thick, passing 1000-hour salt spray test (ASTM B117) without corrosion.
Quality Certification System
- Performance Testing: Each unit undergoes 1.5x rated pressure hydrostatic test (30-min hold, no leakage) and 0.6MPa airtightness testing (soap bubble method).
- Certifications: CE compliant (2014/68/EU PED), ROHS certified, food contact materials meet GB 4806.9-2016 standards.
