Hydrostatic & Pneumatic Testing

Astro Pak provides in-house and onsite Hydrostatic  and Pneumatic pressure testing of gauges, valves, tubing assemblies, and other components, as well as in-place systems, vessels and equipment. Hydrostatic & Pneumatic testing testing can be performed in conjunction with precision cleaning, passivation, cleanliness certification, or clean assembly operations.

Astro Pak is capable of precision cleaning and hydrostatic testing of cryogenic vessels and liquid fuel propellant systems. High purity gas systems and components may be pressure tested and gas quality certified to meet the required standard. Oxidizer gas systems (chlorine, oxygen or ozone) can be pressure tested and cleaned for oxygen service.

At our cleanroom or shop locations, we can hydrostatic pressure test up to 30,000 psi, and pneumatic pressure test up to 10,000 psi. We test using NIST referenced calibration and certification to ASTM standards. We also routinely complete  military standard requirements.
