Pharmaceutical manufacturing demands the highest purity piping materials β SS 316L is the industry standard for product-contact surfaces, with electropolished finish for WFI and pure steam systems. All fittings must meet FDA, cGMP, and ASME BPE requirements where applicable.
Water for Injection (WFI) and pure steam distribution requires electropolished SS 316L with Ra β€0.5ΞΌm internal surface finish. Full traceability, batch certificates, and PMI testing are standard requirements.
Clean-In-Place (CIP) systems and general process piping use SS 316L for product-contact surfaces. SS 304L for non-product-contact utility systems. MSS SP-43 light-wall fittings for low-pressure pharmaceutical service.
Active Pharmaceutical Ingredient (API) synthesis often involves aggressive solvents, acids, and halogens. Hastelloy C276 for chlorinated solvents and HCl. SS 316L for standard organic synthesis piping.
Fermentation, cell culture, and purification systems require ultra-clean SS 316L. Inconel 625 for autoclave and high-pressure sterilization systems. Full ASME BPE compliance for bioprocessing equipment.
