application
- System Intelligent Flow Distribution: Fire protection/HVAC main pipeline diameter reduction branches, large diameter pipes (e.g., 4“) transitioning to smaller branch pipes (e.g., 1”), precisely matching equipment interfaces.
- Equipment Stepwise Power Supply: Air compressor units, multi-stage pump rooms, achieve stepwise flow distribution through diameter reduction structures (e.g., 4“×4”×3″ three-way fittings optimize energy consumption).
- Space-Saving Retrofits: Building pipe shafts and ship engine rooms utilize compact designs (e.g., 1“ × 1” × 1/4″ with a center distance of 28.2 mm) to resolve pipe misalignment issues.
- High-pressure safety diversion: Class 300 grade for hydraulic system branches (e.g., 2“ × 2” × 1″ with a pressure rating of 1500 psi), capable of withstanding 2000 psi impact.
- Upgrading of old pipelines: Municipal water supply pipelines with newly added small-diameter branches (e.g., 6“ main pipe connected to a 2” branch pipe), eliminating the need for pipe cutting during renovation.
avantages
- Versatile Flow Master:
- Over 50 size combinations (e.g., 4“ × 4” × 3“ to 1/2” × 1/2“ × 3/8”), covering all industrial applications;
- Smooth inner wall transitions, branch pipe pressure drop <8%, outperforming welded size transition solutions.
- Dual Pressure Rating All-Round Protection:
- Class 150: General-purpose, 300 psi pressure rating, -29°C to 66°C temperature range;
- Class 300: High-pressure specialized (e.g., 3“×3”×2″ with a 1500 psi pressure rating), 90% increased safety margin.
- Triple-barrier structure:
- Forged cast iron (ASTM A197) one-piece casting, with a 60% improvement in water hammer resistance;
- NPT threaded three-way self-sealing, UL/FM certified with zero leakage;
- Hot-dip galvanized coating >85μm, salt spray resistance >1200 hours.
- Space-Saving Design:
- Small-diameter reducer tees (e.g., 1“×1”×1/4″) save 40% installation space;
- Optimized branch center distance (e.g., 4“×4”×3″ with only 83.8mm), reducing bracket modifications.
- 3-minute rapid installation: Threaded direct screw-in without tools, 8 times faster than flange connections.
emballage
- Ultimate Interface Protection:
- Each threaded port is coated with long-lasting anti-rust grease, and protected with a double layer of silicone caps and heat-shrinkable film;
- Special protection for reducer interfaces: thickened EPE foam rings prevent impact and deformation.
- Smart Graded Packaging:
- ≤2 inches: 15 pieces per box, honeycomb paper tray compartments + variable diameter combination labels (e.g., “2”×2“×1” → DN50×50×25″);
- >2 inches: Single-piece suspended steel frame box, with pressure rating color codes printed on the box (blue = 150/red = 300).
- Revolutionary solution for large items:
- For three-way fittings over 4 inches, use a disassemblable steel structure box with casters and brakes on the bottom;
- Built-in NFC chip for scanning to access installation videos and pressure parameters.
- Dual safety measures:
- Product body laser-engraved with pressure rating and size specifications (e.g., “CL300 4”×4“×3”);
- Outer box labeled with three-way flow direction arrows, with red warning text “Size-changing branch pipe.”

- System Intelligent Flow Distribution: Fire protection/HVAC main pipeline diameter reduction branches, large diameter pipes (e.g., 4“) transitioning to smaller branch pipes (e.g., 1”), precisely matching equipment interfaces.
- Equipment Stepwise Power Supply: Air compressor units, multi-stage pump rooms, achieve stepwise flow distribution through diameter reduction structures (e.g., 4“×4”×3″ three-way fittings optimize energy consumption).
- Space-Saving Retrofits: Building pipe shafts and ship engine rooms utilize compact designs (e.g., 1“ × 1” × 1/4″ with a center distance of 28.2 mm) to resolve pipe misalignment issues.
- High-pressure safety diversion: Class 300 grade for hydraulic system branches (e.g., 2“ × 2” × 1″ with a pressure rating of 1500 psi), capable of withstanding 2000 psi impact.
- Upgrading of old pipelines: Municipal water supply pipelines with newly added small-diameter branches (e.g., 6“ main pipe connected to a 2” branch pipe), eliminating the need for pipe cutting during renovation.
- Versatile Flow Master:
- Over 50 size combinations (e.g., 4“ × 4” × 3“ to 1/2” × 1/2“ × 3/8”), covering all industrial applications;
- Smooth inner wall transitions, branch pipe pressure drop <8%, outperforming welded size transition solutions.
- Dual Pressure Rating All-Round Protection:
- Class 150: General-purpose, 300 psi pressure rating, -29°C to 66°C temperature range;
- Class 300: High-pressure specialized (e.g., 3“×3”×2″ with a 1500 psi pressure rating), 90% increased safety margin.
- Triple-barrier structure:
- Forged cast iron (ASTM A197) one-piece casting, with a 60% improvement in water hammer resistance;
- NPT threaded three-way self-sealing, UL/FM certified with zero leakage;
- Hot-dip galvanized coating >85μm, salt spray resistance >1200 hours.
- Space-Saving Design:
- Small-diameter reducer tees (e.g., 1“×1”×1/4″) save 40% installation space;
- Optimized branch center distance (e.g., 4“×4”×3″ with only 83.8mm), reducing bracket modifications.
- 3-minute rapid installation: Threaded direct screw-in without tools, 8 times faster than flange connections.
- Ultimate Interface Protection:
- Each threaded port is coated with long-lasting anti-rust grease, and protected with a double layer of silicone caps and heat-shrinkable film;
- Special protection for reducer interfaces: thickened EPE foam rings prevent impact and deformation.
- Smart Graded Packaging:
- ≤2 inches: 15 pieces per box, honeycomb paper tray compartments + variable diameter combination labels (e.g., “2”×2“×1” → DN50×50×25″);
- >2 inches: Single-piece suspended steel frame box, with pressure rating color codes printed on the box (blue = 150/red = 300).
- Revolutionary solution for large items:
- For three-way fittings over 4 inches, use a disassemblable steel structure box with casters and brakes on the bottom;
- Built-in NFC chip for scanning to access installation videos and pressure parameters.
- Dual safety measures:
- Product body laser-engraved with pressure rating and size specifications (e.g., “CL300 4”×4“×3”);
- Outer box labeled with three-way flow direction arrows, with red warning text “Size-changing branch pipe.”
