application
- Main pipeline efficient diversion: Fire protection/HVAC main pipelines with equal-diameter branches, flow distribution error <5%, preventing system imbalance.
- Equipment cluster connection: Pump room multi-pump parallel connection, air compressor units, three-way interfaces reduce welding joints by 40%, eliminating leakage risks.
- Compact Space Piping Layout: In building pipe shafts and ship engine rooms, short center distance design (e.g., 1/2″ with only 28.5mm) saves space.
- High-Pressure Safety System: Class 300-rated for hydraulic stations and steam pipelines, withstands 2000psi impact without bursting.
- System Rapid Expansion: When adding new branches to municipal pipelines, threaded direct connection is possible without interrupting the main pipeline.
advantages
- Dual pressure rating for comprehensive coverage:
- Class 150: Economical and versatile, with a pressure rating of 300 psi and a temperature range of -29°C to 66°C;
- Class 300: High-pressure specific (e.g., 2″ with a pressure rating of 1500 psi), with an 80% increase in safety redundancy.
- Triple-reinforced structure:
- Forged cast iron (ASTM A197) one-piece casting, with water hammer impact resistance 50% higher than ordinary cast iron;
- NPT threaded three-way sealing, UL/FM certified with zero leakage;
- Hot-dip galvanized coating >80μm, salt spray resistance >1000 hours.
- Zero flow loss: Equal-diameter design with branch pressure drop <3%, outperforming reducer tees.
- Minute-level installation: Threaded direct screw-on without tools, 10 times faster than flange connections.
- Full-size compatibility: 1/4“-6” covers all scenarios from instrument microtubes to industrial mainlines.
packing
- Threaded Armor Protection:
- Each port is filled with food-grade anti-rust oil, sealed with a silicone cap and heat-shrinkable film;
- The main body is wrapped in pearl cotton and embedded in a high-density EPS mold to prevent collision and breakage.
- Smart Graded Packaging:
- ≤2 inches: 20 pieces per box, honeycomb paper trays with dividers + desiccant, outer box printed with pressure rating color codes (blue = 150/red = 300);
- >2 inches: Single-piece suspended steel frame box, three-way branch pipes fitted with EVA protective caps, box body with ventilation holes for easy forklift handling.
- Revolutionary Solution for Large Items:
- 4“-6” three-way fittings use disassemblable steel structure boxes with anti-slip rubber wheels on the bottom;
- built-in NFC chip for scanning to obtain installation torque and pressure parameters.
- Error-proofing traceability system:
- Product body laser-engraved with “CL150/300” markings;
- outer box labeled with three-way flow direction arrows and “equal-diameter diversion” warning text.
