Testing & Qualification

Verification Through Testing

Keep test feedback connected to engineering and manufacturing as hardware moves from prototype development through qualification and production acceptance.

  • Proof, burst and pressure-cycle testing
  • Leak, thermal and inspection support
  • Program-specific qualification and acceptance

Start with the application

Engineered Around the Mission

Start with the spacecraft, launch vehicle, defense system or aircraft requirement—then identify the appropriate product and engineering path.

Application imagery is illustrative and does not identify a specific customer installation.

Related commercial technology

Same Steelhead Technology. 
Different Requirements.

Commercial and aerospace programs share core Steelhead engineering and manufacturing expertise. Review commercial configurations separately; their ratings and certifications do not automatically apply to aerospace hardware.

Start with the requirement

Bring Us the Mission.

Bring the pressure, gas or fluid, available envelope, mass target, interfaces and qualification requirements. Steelhead can help identify the appropriate platform or development path.
