NEA high‑purity stainless steel BPE tubing follows internal corporate standards that exceed ASME BPE SFT1 and ASTM A270 S2. Tubes are processed by hydrogen bright annealing at a minimum temperature of 1040°C followed by rapid quenching. Every batch undergoes mechanical tests including flaring, flattening and reverse bending, along with eddy‑current testing and 100% full‑length borescope scanning. Chemical composition, outer diameter and wall‑thickness tolerances are strictly controlled.
The maximum inner surface finish reaches 0.5 μm Ra while the outer surface finish can be up to 0.8 μm Ra. Polishing is performed in accordance with ASME/ANSI B46.1 specifications. Finished tubes are sealed in polyethylene bags fitted with plastic end caps and packed in wooden cases to prevent contamination during transit. Custom‑made packaging solutions are available upon request. The product is widely applied in demanding high‑purity fluid transfer conditions for biopharmaceutical, semiconductor and data‑centre sectors.
