6. INSTALLATION AND OPERATING PROCEDURES
6.4 Test the Tree Prior to Installation
(1) Test the tree as described from the following tests.
Note: The sequence can be changed as needed and the tests can be grouped together. Also, as many lines use tubing larger than ¼”, the time expected for pressure stabilization may take longer than others.
(2) The test pressure and duration is customer specified.
(3) The table below indicates the test side of each valve:
NOTE: As the order of the testing may be changed, ensure that all valves are tested in both directions.
