3.9 LEAK TESTING
A. Hydrostatic Leak Test:
1. Test boundaries, valve alignment and closure.
2. Joints visible.
3. Pressure control and overpressure protection of test.
4. System relief devices isolated.
5. Water cleanliness and chemistry (ppm chloride limit on stainless).
6. Hydrotest pressure, considering changes in elevation.
7. Supports completed.
8. Temporary supports where necessary (hydro of steam or gas lines).
9. Variable springs constrained.
10. Expansion joints constrained.
11. Verification of pressure rating of components.
12. Use of strainers to protect equipment.
13. Ambient temperature above minimum.
14. Fill and venting.
15. Time at pressure.
16. Visual inspection for leaks.
17. Tightening of leaking mechanical or flange joints.
18. Flush and water disposal.
19. Dry and clean pipe.
20. System and valve alignment returned to specified condition.
B. Pneumatic Test Piping (typically Small Bore -- 2 inch and smaller -- and below 150 psi)
1. Verify component pressure rating.
