How do you make a test tree for testing pipe with pneumatic?

To create a test tree for testing pneumatic pipes, first design a schematic that outlines the configuration of the pipes, valves, and gauges needed for the test. Ensure that the test tree includes pressure regulators, isolation valves, and measurement points for accurate pressure readings. Assemble the components on a sturdy frame, ensuring all connections are leak-proof. Finally, conduct a preliminary test to verify the integrity of the setup before proceeding with the actual pneumatic testing.
