RFQ and Product Controls
- UNS N06333 and ASTM B726-02(2021) stated exactly
- Heat-resisting or corrosive-service duty and governing equipment specification
- Outside diameter, wall thickness, length and dimensional tolerances
- Automatic no-filler welding route, final annealing and surface condition
- Chemical, mechanical and hardness requirements
- Flattening, flanging and required leak or electric examination route
- ASTM B751 requirements, inspection document, traceability, marking and destination
The material identity must remain traceable from the producing heat and lot through manufacture, welding or seamless processing, heat treatment, testing, inspection documentation, marking and final release.
Scope Boundary
ASTM B726 is limited to the UNS N06333 welded-tube route. It does not cover seamless product or welded pipe, and it does not replace project qualification of temperature duty, corrosion resistance, weld procedure or equipment design.
