The ASTM A860 WPHY70 LR 90° Elbow is a peak-performance wrought fitting for high-pressure transmission lines. Matching API 5L X70 pipe, it provides a massive minimum yield strength of 70,000 PSI. Its Long Radius (LR) design ($1.5D$) ensures high-efficiency flow with minimal pressure drop. These elbows are strictly tested for notch toughness, making them the standard for large-diameter, high-stress pipelines in arctic or seismically active regions.
