Ensuring Integrity: NDT Requirements for Cryogenic Valves

In the manufacturing of cryogenic service valves, Non-Destructive Testing (NDT) is not just best practice - it’s a standard requirement. These valves operate under extreme conditions, and their integrity must be verified without compromising the material.

The most common NDT methods include Penetrant Testing (PT) and Magnetic Particle Testing (MT), both essential for detecting surface and near-surface defects.

However, for critical pressure-containing zones, an additional level of inspection is often necessary.

Radiographic Testing (RT) is frequently performed on these critical areas, as defined in ASME B16.34, to evaluate internal quality. RT is particularly valuable for identifying internal voids, inclusions, or other flaws that PT and MT cannot detect.

At Beize, we prioritize full traceability and quality documentation. That’s why we send our castings to specialized, certified laboratories for detailed inspection. These labs deliver comprehensive RT reports, including radiographic films and expert assessments, ensuring our products meet the highest standards for cryogenic service.
