application
- Pump Station Expansion Project: Main pipeline with equal diameter input, branch pipeline expansion to achieve flow upgrade.
- HVAC System Renovation: Expansion of branches of the chilled water main pipeline to connect to large terminal equipment.
- Fire Protection Network Upgrade: UL/FM certification ensures pressure expansion of sprinkler system branch pipelines.
- Industrial Fluid Network: Stepwise increase in flow rate of chemical pipeline branches for transportation.
- Ship Power System: Expansion of main fuel/coolant pipeline branches in the engine room.
- Agricultural Irrigation Hub: Main pipeline with equal pressure input, branch pipeline expansion for irrigation upgrades.
- Energy Transmission Network: Branch pipeline expansion and diversion at oil and gas pipeline inspection ports.
- Municipal Pipeline Network Node: Main water supply pipeline with equal pressure input, branch pipeline expansion for maintenance access.
advantages
- Stepped expansion design: Main pipe maintains constant diameter for pressure stabilization, while branch pipes seamlessly increase flow rate by 30%.
- Triple high-pressure sealing: 25 bar operating conditions with BSPT tapered threads for zero leakage sealing (main pipe x2 + branch pipe x1).
- Corrosion-resistant matrix: Hot-dip galvanized coating resists corrosion from acidic/alkaline media and marine environments.
- Fluid-optimized structure: Tapered transition in branch pipes reduces vortex resistance by 25%.
- Dual international certifications: UL/FM fire safety and NSF 61 certification (covering models M1110 to M1152).
- Water hammer resistance enhancement: Ductile iron base absorbs pressure fluctuation impact peaks.
- Wide temperature range compatibility: Maintains structural seal integrity from -30°C to 120°C.
- Lifetime maintenance-free commitment: Special annealing process extends the service life of the piping system.
packing
- Differential-diameter port protection: Main pipe injection-molded cover + branch pipe metal flared sleeve.
- Three-dimensional cushioning system: EPE pearl cotton molded stepped wrapping around the three-way fitting body.
- Full-surface armor treatment: Vapor-phase anti-rust film + anti-static bubble columns with triple sealing.
- Anti-misalignment positioning: Laser-cut foam boards with precisely sized stepped slots.
- Flow direction identification system: Main pipe equal diameter arrow printed on outer box + branch pipe expansion symbol (▲).
- Load-bearing grading scheme: ≤2“ uses five-layer corrugated box / ≥2.5” uses steel-band fumigated wooden box.
- Certification special management: NSF certification scope independently labeled (M1110~M1152).
- Anti-Rolling Structure: Asymmetric brackets inside the box secure three-way fittings for zero-displacement transportation.
