ULTRA-PURE SANITARY METALLURGY FOR STERILE API & BIOPHARMACEUTICAL PROCESSING
Engineered alloys for contamination-critical bioprocessing. We stock and supply ASME BPE compliant 316L electropolished tubing, Hastelloy C-22 for aggressive synthesis reactions, and high-purity alloy systems certified down to Ra ≤ 0.25 µm.
SANITARY INTEGRITY & BIO-COMPATIBILITY
Pharmaceutical and biotechnology environments require metallurgical purity that eliminates microbial entrapment, rouging, and pitting corrosion from Clean-in-Place (CIP) and Steam-in-Place (SIP) aggressive sanitization cycles.
ASME BPE & FDA Compliant Hygienic Polishing
Surface finishes controlled to Ra ≤ 0.38 µm mechanically polished and Ra ≤ 0.25 µm electropolished, with comprehensive passivation documentation and boroscopic validation.
Aggressive Corrosion Resistance in API Synthesis
High-molybdenum nickel superalloys (Hastelloy C-22, Alloy 20, Inconel 686) resistant to concentrated chlorides, organic acids, and continuous autoclave sterilization regimes.
Validated Delta Ferrite & Traceability
Ferrite content strictly controlled to < 0.5% (FN < 1) in contact zones to eliminate rouge formation in ultra-pure Water For Injection (WFI) distribution loops. Complete dual-heat traceability with full material test certificates.
