Pressure testing refers to the hydraulic pressure test of the pipeline system using a high-pressure pump to verify the sealing, strength and reliability of the pipeline system. The Elephant pump stands out due to its three key characteristics. Firstly, it enables a gradual and controlled increase in pressure, allowing the pipeline system to adapt smoothly to the rising pressure. Secondly, it ensures pressure stability, avoiding abrupt fluctuations in pressure during the testing process. Lastly, it incorporates overpressure protection mechanisms, prioritizing safety and minimizing risks associated with pressure testing.
