Pressure Test Inspection & Records

Inspection controls, records and reporting for hydrostatic and pneumatic verification of finished pressure-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.

This page focuses on inspection planning, records and release evidence. For the manufacturing service, RFQ inputs and integration with cast/machined pressure-boundary parts, see Pressure & Leak Testing Services.

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.

Upload drawings and 3D models with the form, or email them directly if you prefer.

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

Secure verification
