Y-Type Strainer

I. Product Features: Flow-Optimized Design for Robust Filtration

(A) Structural Design & Filtration Performance

1. Hydrodynamic Optimization
   • 30° Inlet Angle: Strict 30°±2° angle between branch and main pipe reduces pressure drop by 18% (Cv≥150 for DN100), saving 12% annual pumping energy for DN300 pipelines;
   • Self-Cleaning Chamber: 45° sloped screen bottom directs particles to the drain, reducing screen clogging by 60% in steel plant cooling water systems.
2. Graded Filtration System
   • Mesh Accuracy Matrix:

     Filtration Grade	Aperture (μm)	Mesh Size	Applicable Media
     Coarse	500-250	30-60	Cooling water, crude oil
     Medium	250-50	60-300	Hydraulic oil, chemicals
     Fine	50-10	300-1500	Ultra-pure water, APIs

   • Anti-Clogging Technology: Wedge wire screen (±0.01mm slot tolerance) resists fiber entanglement 50% better than perforated screens, minimizing downtime in paper mill applications.

(B) Material & Application Compatibility

• Body Materials: Forged steel (A105: standard), stainless steel (F316L: acid/alkali), duplex (2205: chloride), Hastelloy (C-276: strong corrosion), rated for Class 150–2500 (PN16–420), -196℃–650℃;
• Surface Treatments: Epoxy powder coating (300μm) for marine use (2000-hour salt spray); electropolished interior (Ra≤0.4μm) for food-grade compliance (FDA 21 CFR 177.2600).

II. Manufacturing Processes: Precision Forging & Quality Control

(A) Key Manufacturing Steps

1. Die Forging Technology
   • Hot Forging: 2000-ton presses refine grains to ASTM No.10+ (forging ratio ≥4:1), UT tested for ≥Φ1.2mm defects;
   • Laser Cutting: Fiber lasers cut 316L mesh (±0.05mm accuracy), rounded edges (R≥1mm) to prevent pipe damage.
2. Precision Machining & Assembly
   • 5-Axis CNC: Achieves ≤0.003mm flatness for flanges, ±0.01mm coaxiality for screen seats;
   • Automatic Welding: TIG welding with 99.99% pure argon, 100% RT inspection per ASME BPVC Section VIII.
3. Performance Testing

• Hydrostatic Test: 1.5x pressure (water, 30min), ≤0.3% drop (e.g., 9.0MPa for Class 600);
• Gas Seal Test: 1.1x pressure (helium), ≤5×10⁻¹⁰Pa·m³/s leakage (better than API 598 Class IV);
• Flow Test: ≤0.04MPa pressure drop at rated flow (e.g., 150m³/h for DN200), 15% better than industry standards.

III. Product Applications: Critical Protection for Global Industries

(A) Oil & Gas

• Wellhead Protection: Sulfur-resistant strainers (NACE MR0175) with duplex 2507 mesh last 8 years in 1500ppm H₂S, 3x longer than standard SS;
• LNG Cryogenic Systems: F316L body strainers (-162℃) with API 6A PR2 certification prevent ice blockages in loading arm inlets.

(B) Chemical & Petrochemical

• Polymer Reactors: 50μm strainers handle 25% solids-laden PE slurry, enabling 10-minute screen change to minimize downtime;
• Chlor-Alkali Plants: Hastelloy C-276 strainers resist 180,000ppm Cl⁻ for 10 years, extending maintenance cycles from 6 months to 2 years.

(C) Power & Energy

• Supercritical Power Plants: High-temp strainers (F91 body) with Inconel 718 mesh pass 100,000 load cycles, ΔP fluctuation ≤5%;
• PV Silicon Production: Electropolished 316L strainers control 99.99% pure trichlorosilane with ≤1×10⁻⁹Pa·m³/s leakage.

(D) Municipal & Environmental

• Wastewater Treatment: DN1200 strainers with tungsten carbide coating last 7 years in 15% solids-laden sewage, cutting replacement costs by 40%;
• District Heating: Self-cleaning strainers (100μm) reduce pressure loss by 30%, improving network efficiency by 5%.

IV. Advantages: TIANYU’s Global Competitiveness
