Notes:

1. At the connecting parts the transition of the cylinder into the socket can be performed in the form of a ledge (variant I) or with bias (option II).

2. The wall thickness of the connecting parts is greater than the thickness of the pipe wall . Thickening of the walls is achieved by reducing the inner diameter, as shown in the drawing dash-dotted line.

Notes:

1. Bolt holes on flanges of fittings shall be located so that they weren’t neither on the vertical nor on the horizontal axis of the flange.

2. The wall thickness of the connecting parts is greater than the thickness of the pipe wall . Thickening of the walls is achieved by reducing the inner diameter, as shown in the drawing dash-dotted line.

3. Allow the execution of flanges with projections according to the sizes and .
