Note:
- 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
- Specifically designed for space-constrained pipe diameter changes, it simultaneously achieves 90° directional adjustment and pipe diameter conversion, breaking through the layout restrictions of traditional elbow + reducer pipes.
- Key applications include compact equipment interfaces (such as pump valve assemblies, heat exchangers), ship engine room pipes, and prefabricated systems in modular factories, among other complex space scenarios.
- In pipeline renovation projects, it replaces multi-component assembly solutions, reducing installation space by 50%.
advantages
- Revolution of Space Effects: Dual-actionIntegrated ElbowReducer An all-in-one combines the usual elbows and reducers into one component. The long radius design (R=1.5D) ensures low flow resistance, and makes the most effective use of installation space.
- Projectiles With Pressure: Integrally forged construction + fully welded joints can contain pressure equivalent to that of straight pipes and remove the risk of joint leakage.
- Smart Flow Channel Design: The gradual cross-section technology reduces 35% of the turbulence, which greatly decreases the loss of system energy.
- Corrosion protection system (double anti-corrosion material): Inner tank: carbon steel-inner hot-dip galvanized (salt spary resistance 1000h) or inner epoxy coal taring (acid and alkali resistant). Stainless steel: Prohibited Pickling and passivation with acid, should be in strict conformity with ASME B31. 3)
- Installation Efficiency Upgrade: 60% reduction in the number of welds, reducing construction time by 40%, especially for high-altitude/constrained space operation.
- Covers Full Operating Condition: all specifications from 2“×1-1/2” to 24“×12”, compatible with SCH XXS pipes and other extreme thick walled pipes .
packing
- Asymmetric protection system:
- Use irregular foam molds to precisely fix variable diameter curved surfaces.
- Mark the outer box with a “large diameter end →” direction indicator.
- Dual diameter dedicated protection:
- Large diameter end: steel flange cover + rubber buffer ring.
- Small diameter end: engineering plastic screw-in protective cover.
- Marine-grade anti-rust solution:
- Carbon steel parts: VCI vapor phase anti-rust bag + anti-rust oil coating.
- Stainless steel components: Vacuum-sealed aluminum foil packaging + desiccant

- Projectiles With Pressure: Integrally forged construction + fully welded joints can contain pressure equivalent to that of straight pipes and remove the risk of joint leakage.
- Smart Flow Channel Design: The gradual cross-section technology reduces 35% of the turbulence, which greatly decreases the loss of system energy.
- Corrosion protection system (double anti-corrosion material): Inner tank: carbon steel-inner hot-dip galvanized (salt spary resistance 1000h) or inner epoxy coal taring (acid and alkali resistant). Stainless steel: Prohibited Pickling and passivation with acid, should be in strict conformity with ASME B31. 3)
- Installation Efficiency Upgrade: 60% reduction in the number of welds, reducing construction time by 40%, especially for high-altitude/constrained space operation.
- Covers Full Operating Condition: all specifications from 2“×1-1/2” to 24“×12”, compatible with SCH XXS pipes and other extreme thick walled pipes .
- Asymmetric protection system:
- Use irregular foam molds to precisely fix variable diameter curved surfaces.
- Mark the outer box with a “large diameter end →” direction indicator.
- Dual diameter dedicated protection:
- Large diameter end: steel flange cover + rubber buffer ring.
- Small diameter end: engineering plastic screw-in protective cover.
- Marine-grade anti-rust solution:
- Carbon steel parts: VCI vapor phase anti-rust bag + anti-rust oil coating.
- Stainless steel components: Vacuum-sealed aluminum foil packaging + desiccant
