Hydrostatic Pressure Testing Machine serves the purpose the internal pressure tolerance pipes, fittings, and assemblies utilized for fluid
Purposes:
Hydrostatic pressure testing machines are primarily designed to assess the internal pressure resistance of plastic pipes, fittings, and assemblies.
Under controlled conditions, products made from materials like PP, PE, PVC, PVC-C, and ABS are subjected to specific internal pressure for a defined period to evaluate their pressure-bearing capability and check for failures such as leakage, bursting, or excessive deformation.
This testing is crucial for ensuring the quality, safety, and reliability of plastic pipes and related components in fluid transportation systems, which are widely applied in water treatment, sewage disposal, gas transmission, and industrial fluid conveyance.
