application
- Building Plumbing Systems: Main pipelines with bidirectional equal-diameter branching for balanced water supply.
- Fire Protection Network Layout: UL/FM certification ensures multi-directional equal-pressure branching for sprinkler systems.
- HVAC Engineering: Main chilled water pipelines with equal-diameter three-way branching for distribution.
- Industrial Fluid Networks: Chemical pipelines with equal-pressure multi-directional medium distribution.
- Ship Power Systems: Equal-diameter fuel/coolant three-way branching within engine room spaces.
- Agricultural Irrigation Hub: Main pipeline of the pump station with equal-pressure branch pipes for synchronized irrigation.
- Energy Transmission Network: Equal-diameter three-way branching at inspection ports of oil and gas pipelines.
- Municipal Pipeline Network Nodes: Equal-pressure branching at maintenance interfaces on the main water supply pipeline.
advantages
- Three-way equal pressure design: Precise flow distribution ensures balanced pressure across all branches.
- High-pressure sealing structure: Triple zero-leakage sealing with BSPT tapered threads under 25 bar conditions.
- Full environmental corrosion resistance: Hot-dip galvanized coating resists chemical media/salt spray corrosion.
- Enhanced fluid performance: Smooth inner wall channels reduce vortex resistance by 20%.
- Dual international certifications: UL/FM fire safety certification and NSF 61 certification (applicable to M0901/M0902/M0913 models).
- Water hammer resistance: Ductile iron base absorbs pressure fluctuation peaks.
- Wide temperature range stability: Maintains structural integrity from -30°C to 120°C.
- Lifetime maintenance-free guarantee: Special processes extend the service life of the piping system.
packing
- Three-port three-dimensional protection: custom injection molded cover nests three threaded ports.
- Node buffer system: EPE pearl cotton molded wrap tee body shockproof.
- Full surface armor treatment: vapor phase anti-rust film + winding bubble column sealing.
- Intelligent positioning and packing: laser-cut foam board accurately triangular card position according to size.
- Diversion Identification System: Three-way fluid red indicator arrow printed on the outer box.
- Load-bearing classification scheme: ≤1.5″ with five-layer corrugated box / ≥2″ with steel strip wooden box.
- Special certification management: NSF certified models are independently labeled and test reports are attached.
- Anti-displacement structure: Triangular bracket in the box fixed tee zero displacement transportation.
