T-Type Strainer

I. Product Features: Optimized Right-Angle Design for Precision Filtration

(A) Structural Design & Filtration Performance

1. Compact Right-Angle Layout
   • Space-Saving Design: T-type three-way structure (90°±0.5° angle) reduces installation length by 25% (DN100 ≤300mm), ideal for narrow spaces like sandwich pipelines and offshore platforms;
   • Quick-Change Filter Chamber: Branch-end quick-release flanges (40% fewer bolts) enable ≤15-minute screen replacement (DN200), supporting online maintenance without system shutdown.
2. Multi-Grade Filtration System
   • Mesh Accuracy Matrix:

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

   • Anti-Clogging Technology: Wedge wire screen (slot tolerance ±0.01mm) resists fiber entanglement 60% better than perforated screens, reducing cleaning frequency from 2x/day to 1x/week in paper mill applications.

(B) Material & Application Compatibility

• Body Materials: Forged steel (A105: -29℃~427℃), stainless steel (F316L: acid/alkali), duplex (2205: chloride resistance), Hastelloy (C-276: strong corrosion), rated for Class 150–2500 (PN16–420);
• Surface Treatments: Polyamide coating (150μm) for marine use (1500-hour salt spray); electropolished interior (Ra≤0.4μm) for food-grade compliance (FDA 21 CFR 177.2600).

II. Manufacturing Processes: Intelligent Forging & Quality Assurance

(A) Key Manufacturing Steps

1. Precision Forging & Forming
   • Die Forging: 1600-ton presses refine grains to ASTM No.10+ (forging ratio ≥5:1), UT tested for ≥Φ1.5mm defects;
   • Laser Cutting: Fiber lasers cut 316L mesh (±0.05mm accuracy), deburred edges (Ra≤1.6μm) to prevent pipe scratches.
2. Precision Machining & Assembly
   • 5-Axis CNC: Achieves ≤0.003mm flatness for flanges, ±0.01mm coaxiality for screen seats;
   • Automatic Welding: TIG welding (±2A current stability) for branch connections, 100% RT inspection per ASME BPVC Section VIII.
3. Performance Testing

• Hydrostatic Test: 1.5x pressure (water, 45min), ≤0.5% drop (e.g., 13.5MPa for Class 900);
• Gas Seal Test: 1.1x pressure (helium), ≤5×10⁻¹⁰Pa·m³/s leakage (better than API 598 Class IV);
• Pressure Drop Test: ≤0.05MPa at rated flow (e.g., 120m³/h for DN200), 20% lower than industry standards.

III. Product Applications: Preferred for Compact Space Filtration

(A) Oil & Gas

• Shale Gas Wells: Sulfur-resistant strainers (NACE MR0175) with duplex 2507 mesh last 8 years in 1000ppm H₂S, 3x longer than standard SS;
• LNG Terminals: Cryogenic strainers (F316L body) at -162℃, API 6A PR2-certified for loading arm pipelines, preventing ice blockages.

(B) Chemical & Petrochemical

• Reactor Inlets: 50μm strainers handle 20% solids-laden PE slurry, enabling 10-minute screen change to minimize downtime;
• Chlor-Alkali Plants: Hastelloy C-276 strainers resist 200,000ppm 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

• High-Rise Water Supply: DN150 strainers (100μm) protect pumps from rust/sediment, ≤0.03MPa pressure drop for efficient water supply;
• Industrial Wastewater: Wear-resistant strainers (tungsten carbide coating) last 7 years in 15% solids-laden sewage, cutting replacement costs by 40%.
