Step-by-Step Instructions to Model This in SolidWorks:

Step 1: Create Base Pipe (Vertical Component)

Open SolidWorks > New Part.

Choose Front Plane > Sketch.

Create a circle of Ø72 mm (outer diameter).

Offset it inward by wall thickness (say 3 mm) to hollow it.

Use Extruded Boss/Base to create a 120 mm vertical extrusion.

Step 2: Create Horizontal Pipe (Elbow)

Choose Right Plane > Sketch.

Draw a centerline, followed by a quarter circle (R72) employing the arc tool (elbow radius).

Draw the pipe thickness (offset arc by ~3 mm inside).

Employ Extruded Boss/Base along this path to form the elbow (or Swept Boss/Base if necessary).

Combine it with the vertical pipe.

Step 3: Make Flange

On the top face of the vertical pipe, draw a flange shape:

Draw an ellipse-type flange (120 mm long, 60 mm wide).

Add 2 bolt holes Ø10 mm as indicated in top view.

Extrude the flange upward by 10 mm.

Similar steps are to be repeated for the horizontal end flange of the elbow.
