PART NUMBER ANALYSIS

To properly select or replace this material

Construction and Key Features

Inclusion in a nuclear product line does not, on its own, constitute qualification, client approval, or project-specific certification. Supporting documentation matching the exact style is required.

Selecting the Proper Grade

Identify the construction code, quality assurance requirements, traceability, client specifications, and operating conditions prior to recommending a grade.

To compare constructions: LATTYgraf HPML and TEADIT GR 1700. Number of layers, metallic foil reinforcement, and oxidation protection must be evaluated.

KEY COMPARISON CRITERIA

The NUC suffix must be maintained: a standard HPML is not automatically interchangeable with a nuclear-grade version.
