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 coaxial diameter change connections in piping systems to achieve smooth flow/pressure transition and avoid fluid turbulence impact.
- Specially designed for diameter changes in high-pressure systems, commonly used in key nodes such as pump valve inlets and outlets, instrumentation lines, and main pipeline pressure reduction.
- Indispensable in precision systems that require strict alignment of fluid centerlines (such as pharmaceutical production lines and laboratory piping).
avantages
- Smooth zero interference transition: high-precision conical structure, laminar flow transition can be obtained, 40% lower pressure loss than eccentric reducers.
- Can handle high pressure: integrally forged and fully welded, equal strength with straight pipes to avoid leak risk in bolt connection;
- The space-Optimized Design Saves 50% of the Installation Space, Particularly applicable to small area installation such as equipment room basement small cell.
- Corrosion Protection System of Dual-MaterialConstruction material: Carbon steel, anti-corrosive treatment by hot-dip galvanizing (20 years life duration) or Conventional epoxy powder coating (chemical-resistant)Surface finish of all components: Stainless steel, electrolytic polishing – Ra ≤ 4 μm
- Universal compatibility: it covers the complete range with specifications from 3/4”× 1/2” to 24” × 10”, fulfilling system requirements from DN15 up to DN600.
- Revolution in installation: Welded connections (instead of flange assemblies & reducer sections) reduces leak, and shortens the construction time by over 60% .
emballage
- Conical component protection:
- ≤8″: PE foam molded tray + reinforced corrugated box
- 8″: Steel banded wooden box + internal conical support frame
- Differentiated port protection:
- Large diameter end: Biodegradable plastic blind plate + anti-collision rubber ring
- Small-diameter end: Screw-in nylon cover + silicone seal
- Anti-corrosion core technology:
- Carbon steel components: VCI vapor phase anti-corrosion film + anti-corrosion oil coating
- Stainless steel components: Vacuum-sealed moisture-proof aluminum foil packaging
- Smart logistics identification: Laser-engraved flow direction arrows and slope markers, with triple traceability QR codes (specifications/material/process) affixed to the outer box.

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 coaxial diameter change connections in piping systems to achieve smooth flow/pressure transition and avoid fluid turbulence impact.
- Specially designed for diameter changes in high-pressure systems, commonly used in key nodes such as pump valve inlets and outlets, instrumentation lines, and main pipeline pressure reduction.
- Indispensable in precision systems that require strict alignment of fluid centerlines (such as pharmaceutical production lines and laboratory piping).
- Smooth zero interference transition: high-precision conical structure, laminar flow transition can be obtained, 40% lower pressure loss than eccentric reducers.
- Can handle high pressure: integrally forged and fully welded, equal strength with straight pipes to avoid leak risk in bolt connection;
- The space-Optimized Design Saves 50% of the Installation Space, Particularly applicable to small area installation such as equipment room basement small cell.
- Corrosion Protection System of Dual-MaterialConstruction material: Carbon steel, anti-corrosive treatment by hot-dip galvanizing (20 years life duration) or Conventional epoxy powder coating (chemical-resistant)Surface finish of all components: Stainless steel, electrolytic polishing – Ra ≤ 4 μm
- Universal compatibility: it covers the complete range with specifications from 3/4”× 1/2” to 24” × 10”, fulfilling system requirements from DN15 up to DN600.
- Revolution in installation: Welded connections (instead of flange assemblies & reducer sections) reduces leak, and shortens the construction time by over 60% .
- Conical component protection:
- ≤8″: PE foam molded tray + reinforced corrugated box
- 8″: Steel banded wooden box + internal conical support frame
- Differentiated port protection:
- Large diameter end: Biodegradable plastic blind plate + anti-collision rubber ring
- Small-diameter end: Screw-in nylon cover + silicone seal
- Anti-corrosion core technology:
- Carbon steel components: VCI vapor phase anti-corrosion film + anti-corrosion oil coating
- Stainless steel components: Vacuum-sealed moisture-proof aluminum foil packaging
- Smart logistics identification: Laser-engraved flow direction arrows and slope markers, with triple traceability QR codes (specifications/material/process) affixed to the outer box.
