Smooth Directional Change with Reduced Flow Resistance

The long radius 90 degree elbow is designed to provide a smoother directional change compared to standard elbows, helping reduce flow resistance and pressure loss in piping systems.
With an extended bending radius, fluid flow transitions more gradually, resulting in improved hydraulic performance and reduced stress on pumping systems.
A customer in Singapore reported that his pump system was operating near its limit. Adding additional standard 90-degree elbows would have increased system resistance. By replacing them with long radius elbows, system performance remained stable within operating requirements.
The long radius 90 degree elbow is manufactured from malleable iron through casting with a hot-dip galvanizing process. Sizes range from DN15 to DN100.

This fitting is suitable for pipeline systems installed along walls or within confined spaces where smooth directional transitions are required.
Compared with standard elbows, the long radius design provides improved alignment and reduced protrusion in installation layouts.
Jianzhi Group manufactures these fittings and holds BSI and SNI certifications. The company has also participated in drafting more than 20 national standards in China.
The minimum order value is 10,000 RMB, and mixed sizes are acceptable within a single order.

The hot-dip galvanized coating provides long-term corrosion resistance for water and outdoor piping systems.
