Pressure & Leak Test Verification

Hydrostatic and pneumatic testing for finished flow and boundary components.

Validate the finished boundary condition

Pressure or leak testing should be performed after ports, sealing surfaces, cleaning and final boundary configuration are defined. The inspection plan must identify medium, pressure, hold time, allowable leakage and required records.

Planning points

  • Confirm material and visual condition before testing
  • Inspect plugs, fixtures and connection method
  • Protect threads, sealing surfaces and thin sections
  • Test after the appropriate machining and cleaning operations
  • Use guarding, exclusion zones and written procedures for pneumatic tests
  • Retain the requested pressure curve, result data or test report

Qualification evidence

Sample test procedures and report formats can be provided during project review. The binding requirement remains the drawing, purchase specification and mutually agreed acceptance criteria.

Start with the drawing

Send the alloy, annual quantity and critical requirements.

Email is the fastest route for drawings and 3D files. The short form is available when email is inconvenient.

For the fastest drawing review, include:
  • 2D drawing / 3D file and revision
  • Material grade or service environment
  • Annual quantity or expected lot size
  • Critical tolerances, finish, inspection or pressure-test requirements

For drawings and 3D files, use direct email. info@chinaprecisionmetal.com.
