Hydrostatic Testing Services

Comprehensive high-pressure water testing for valve integrity verification, shell strength validation, and seat leakage assessment per industry standards.

High-Pressure Water Testing

Our hydrostatic testing services provide comprehensive pressure testing using water as the test medium. This method is ideal for verifying valve shell integrity, seat tightness, and overall structural soundness under controlled pressure conditions.

Shell Pressure Testing

Verify valve body integrity under maximum rated pressure

Seat Leakage Testing

Measure and verify acceptable seat leakage rates

Backpressure Testing

Test valve performance under reverse pressure conditions

Types of Hydrostatic Tests

Comprehensive testing protocols for different valve applications and requirements

Shell Test

High-pressure test to verify valve body and bonnet integrity under maximum design pressure.

  • • Test pressure: 1.5 x design pressure
  • • Duration: Minimum 15 minutes
  • • No visible leakage permitted
  • • Full structural verification

Seat Test

Low-pressure test to measure seat leakage and verify closure effectiveness.

  • • Test pressure: 1.1 x design pressure
  • • Leakage measurement and recording
  • • Acceptable limits per standards
  • • Seat integrity verification

Backpressure Test

Reverse pressure test to verify valve performance under backpressure conditions.

  • • Reverse flow testing
  • • Backpressure capability verification
  • • Seal performance under reverse pressure
  • • Operational verification
