application
- Chemical mixing system: Main pipes of equal diameter maintain main line pressure, while branch pipes of varying diameters precisely add auxiliary materials.
- HVAC engineering: Chilled water main pipes deliver at equal pressure, while branch pipes of varying diameters adapt to different terminal equipment.
- Fire protection network upgrade: UL/FM certification ensures stable pressure in main pipes and throttling and diversion in branch pipes for sprinkler systems.
- Industrial Equipment Layout: compressor main pipes maintain equal diameter output, while branch pipes vary in diameter to connect to pressure gauges.
- Ship Ballast System: main pipes in the engine room maintain equal diameter water supply, while branch pipes vary in diameter to control compartment flow.
- Agricultural irrigation hubs: Main pipes in pump stations maintain equal pressure, while branch pipes vary in diameter to match different irrigation zones.
- Energy sampling networks: Main pipes in oil and gas pipelines maintain equal diameter for detection, while branch pipes vary in diameter for sampling diversion.
- Municipal water supply nodes: Main roads maintain equal pressure, while branch pipes vary in diameter to adapt to different district requirements.
advantages
- Main pipe equal diameter design: Ensures stable fluid pressure/flow throughout the main line.
- Triple high-pressure sealing: Zero leakage at 25 bar operating conditions with BSPT tapered threads (main pipe x2 + branch pipe x1).
- Precise fluid control: Tapered branch pipes enable flow distribution according to demand.
- Corrosion-resistant matrix: Hot-dip galvanized coating resists industrial exhaust fumes and marine salt spray corrosion.
- Dual international certifications: UL/FM fire safety and NSF 61 certification (applies to models M1310–M1337, excluding M1311).
- Impact-resistant reinforcement: Ductile iron base absorbs water hammer impacts from branch pipe diameter changes.
- Wide temperature range reliability: Maintains triple interface seal integrity from -30°C to 120°C.
- Installation efficiency innovation: Single unit achieves main pipe pressure regulation + branch pipe flow control, reducing components by 50%.
packing
- Equal-diameter port collaborative protection: dual main pipe injection-molded cover + branch pipe metal reducer sleeve.
- Asymmetric cushioning system: EPE pearl cotton molded and bonded to the main pipe’s equal-diameter flat surface + branch pipe reducer curved surface.
- Full-surface armor sealing: rust-proof oil impregnation + stretch film + bubble column triple protection.
- Precision positioning slots: laser-cut foam board fixed to the three-way interface according to dimensions.
- Flow direction identification system: Main pipe equal diameter arrow (→→) and branch pipe variable diameter symbol (▼) printed on the outer box.
- Load-bearing grading scheme: ≤1.5“ uses five-layer corrugated boxes/≥2” uses steel-band fumigated wooden boxes.
- Certification-specific labeling: NSF-certified models have independent labels (M1310~M1337, excluding M1311).
- Anti-Rolling Structure: T-shaped brackets inside the box + counterweight blocks on the side of the branch pipes to prevent tipping.
