ASME B16.9 Long Radius Elbow (LRE) refers to a core pipe fitting for pipeline system direction change, with a standard curvature radius R=1.5D (D = Nominal Diameter of the elbow), which features low flow resistance and smooth medium transmission. HT PIPE is a leading stockist and global exporter with over 16 years of expertise in international trade.

Key Basic Parameters
Curvature radius: R=1.5DN (DN = Nominal Diameter, the core difference from short radius elbow (R=1.0DN))
Common angles: 90° (the most universal specification),45° (secondary common specification)
Wall thickness grade: SCH40, SCH80, XS, XXS, SCH160, STD (matching the wall thickness of the connected pipe)
Unit: Nominal diameter (DN/mm, NPS/inch). Outer diameter (OD/mm/inch). Curvature radius/center to end dimension (mm/inch)
Long Radius Elbow Advantages
- 1.5D long radius design, reduce pipeline pressure loss and medium turbulence.
- Precision forming, strict dimensional tolerance, easy on-site installation.
- Multiple high-quality materials optional, adapt to corrosion/high temperature/high pressure working environment.
- Compliant with international mainstream standards, global export applicable.
