What is the primary purpose of a hydrostatic test in pipelines?

• A. To verify system integrity under pressure
• B. To test for color of the fluid
• C. To measure flow rate
• D. To calibrate sensors

Answer: (A)

The test checks whether a pipeline can safely contain pressure and stay intact under service conditions. A hydrostatic test fills the system with water and raises the pressure to a specified level to reveal leaks, weak welds, or deformations that could fail once in operation. This verifies structural integrity and the ability to withstand the pressures it will experience in service, meeting safety and code requirements. The other options don’t fit because color inspection doesn’t assess strength or leaks, measuring flow rate is a separate performance test, and calibrating sensors isn’t about confirming the pipe’s ability to hold pressure.
