ASME B16.9 90 Degree Long Radius Elbow ASTM A420 WPL6 & ASTM A234 WPB for Singapore Projects
Haihao Group recently completed a shipment of ASME B16.9 90 degree long radius elbow ASTM A420 WPL6 and ASME B16.9 90 degree long radius elbow ASTM A234 WPB to a Singapore client involved in industrial pipeline construction.
Unlike generic suppliers, we focus on matching material performance to actual service conditions—whether low-temperature LNG systems or standard high-pressure pipelines.
What Makes This Shipment Different?
Many suppliers simply offer elbows. This project required:
- Two material grades for different service environments
- Strict compliance with ASME B16.9
- Verified impact performance for low-temperature service
- Fast turnaround for project deadlines
That’s where Haihao Group delivers real value.

Why Engineers Prefer Long Radius Elbows
Choosing the right elbow impacts system efficiency more than most realize.
- Reduced turbulence → better flow efficiency
- Lower pressure drop → energy savings
- Less wear → longer pipeline life
Both ASME B16.9 90 degree long radius elbow ASTM A420 WPL6 and ASTM A234 WPB are designed with a 1.5D radius to ensure optimal performance.
