A long radius (LR) plain end elbow is a 90° or 45° fitting where the centerline radius is typically 1.5 times the nominal pipe diameter ($1.5D$). This gradual curve reduces friction, pressure drop, and product shear.Flow: Smoother transition than short radius elbows; ideal for viscous liquids.Connection: Butt-weld ends for permanent, high-purity orbital welding.Finish: Polished ID (Ra < 0.8μm) ensures no bacterial entrapment.
