Remarque :
- The thickness of above form refers to large end OD, and thickness of small end OD is different.
- For size DN 150, it is also available with 165.1 mm as per EN 10255.
application
- Used for variable diameter connections between main pipes and branch pipes in piping systems to achieve differentiated flow/pressure distribution, such as high-flow main pipe delivery and low-flow branch pipe diversion scenarios.
- Suitable for space-constrained variable diameter nodes, commonly found in pump valve interfaces, equipment inlets and outlets, and high-pressure systems such as pipe network branch renovations.
- It is irreplaceable in situations where a compact variable diameter solution is required and flange connections need to be avoided.
avantages
- Engineering Adaptability: Offers dozens of main pipe-branch pipe combinations (3/4“×1/2” to 24“×10”), precisely matching system size transition requirements.
- High-Pressure System Specialization: Compact integrated structure + fully welded joints, with pressure-bearing capacity equivalent to straight pipes, eliminating the risk of flange connection leaks.
- Dual-Effect Energy-Saving Design: Structural Energy Savings: Eliminates flange bolt assemblies, reducing system weight by 30%;Fluid Energy Efficiency: Optimized transition curves reduce turbulence energy loss.
- Zero-Maintenance Sealing: Integrated forged forming combined with precision beveled edges achieve permanent metal sealing, with a maintenance-free lifespan exceeding 20 years.
- Corrosion Defense Matrix: Carbon Steel: Hot-dip galvanized (≥85μm) or epoxy black paint (dual coating)Stainless steel: Electrolytic polishing or acid washing and passivation, Ra ≤ 0.8 μm
- Installation Revolution:Single-piece butt welding replaces flange assemblies + reducers + tees, saving 60% installation time.
emballage
- Intelligent Graded Protection:
- ≤6″: High-strength corrugated box + EPS molded inner lining
- 6″: Steel-reinforced wooden box + customized foam alloy bracket
- Differentiated Port Protection:
- Main pipe end: Metal blind plate + cushioning rubber ring
- Branch pipe end: Engineering plastic screw cap + silicone seal
- Anti-corrosion technology:
- Carbon steel components: VCI + anti-corrosion oil dual protection, withstands 120 days of sea transport
- Stainless steel components: Nitrogen-filled sealed bags
- Streamlined traceability system:
- Laser-etched three-code integrated identification (model/material/batch number), scan to access comprehensive data.

Remarque :
- The thickness of above form refers to large end OD, and thickness of small end OD is different.
- For size DN 150, it is also available with 165.1 mm as per EN 10255.
- Used for variable diameter connections between main pipes and branch pipes in piping systems to achieve differentiated flow/pressure distribution, such as high-flow main pipe delivery and low-flow branch pipe diversion scenarios.
- Suitable for space-constrained variable diameter nodes, commonly found in pump valve interfaces, equipment inlets and outlets, and high-pressure systems such as pipe network branch renovations.
- It is irreplaceable in situations where a compact variable diameter solution is required and flange connections need to be avoided.
- Engineering Adaptability: Offers dozens of main pipe-branch pipe combinations (3/4“×1/2” to 24“×10”), precisely matching system size transition requirements.
- High-Pressure System Specialization: Compact integrated structure + fully welded joints, with pressure-bearing capacity equivalent to straight pipes, eliminating the risk of flange connection leaks.
- Dual-Effect Energy-Saving Design: Structural Energy Savings: Eliminates flange bolt assemblies, reducing system weight by 30%;Fluid Energy Efficiency: Optimized transition curves reduce turbulence energy loss.
- Zero-Maintenance Sealing: Integrated forged forming combined with precision beveled edges achieve permanent metal sealing, with a maintenance-free lifespan exceeding 20 years.
- Corrosion Defense Matrix: Carbon Steel: Hot-dip galvanized (≥85μm) or epoxy black paint (dual coating)Stainless steel: Electrolytic polishing or acid washing and passivation, Ra ≤ 0.8 μm
- Installation Revolution:Single-piece butt welding replaces flange assemblies + reducers + tees, saving 60% installation time.
- Intelligent Graded Protection:
- ≤6″: High-strength corrugated box + EPS molded inner lining
- 6″: Steel-reinforced wooden box + customized foam alloy bracket
- Differentiated Port Protection:
- Main pipe end: Metal blind plate + cushioning rubber ring
- Branch pipe end: Engineering plastic screw cap + silicone seal
- Anti-corrosion technology:
- Carbon steel components: VCI + anti-corrosion oil dual protection, withstands 120 days of sea transport
- Stainless steel components: Nitrogen-filled sealed bags
- Streamlined traceability system:
- Laser-etched three-code integrated identification (model/material/batch number), scan to access comprehensive data.
