pipe elbow 3d model

Create a realistic, engineering-grade 3D model of a symmetric 90-degree pipe elbow joint. The elbow consists of two straight cylindrical pipe segments of equal length and equal diameter, connected at a precise 90-degree angle, forming a perfect L shape. Both pipe ends are identical in size and geometry. The pipe has a circular cross-section, uniform wall thickness, and a hollow interior visible at both open ends. The outer diameter and inner diameter remain constant along the entire elbow. There is no tapering, no deformation, and no rounding beyond the smooth 90-degree bend. Edges are clean and sharp at the pipe ends. Material appears as industrial PVC or HDPE. Surface is smooth and matte. The object is centered in space, shown in a clear 3D perspective view. The model must be dimensionally accurate and suitable for technical or engineering visualization.
