Suction elbow pipe sections

We have been contracted to complete a series of different suction elbow patterns. Each one has a different configuration, inside diameter, flange size, hand hole clean out position, etc. We develop the models and pattern designs from drawings with input from the customer. Pictured below are the first two in what we hope will be a long series of orders.
