FAQ — pharmaceutical industry pressure vessels
What is the role of pressure vessels in the pharmaceutical industry?
Pharmaceutical pressure vessels fulfill five critical functions: (1) Autoclave sterilization of final packaging and process equipment (F0 ≥ 12 min at 121°C), (2) Fermentation of biological API in bioreactors (pH, DO, temperature-controlled), (3) Chemical API synthesis in stainless steel reaction vessels with jacket heating, (4) Storage of WFI (Water for Injection), purified water, and buffer solutions under N₂ blanket, (5) CIP tanks with certified cleaning systems for cleaning validation.
What qualification documentation is mandatory for pharmaceutical pressure vessels?
Compliant with GAMP 5 and GMP Annex 1 (2022), mandatory: URS (User Requirement Specification), DQ (Design Qualification), FAT (Factory Acceptance Test), SAT (Site Acceptance Test), IQ (Installation Qualification), OQ (Operational Qualification), and PQ (Performance Qualification). Additionally: material certificates EN 10204 3.1, weld qualification report EN ISO 15614-1, surface measurement report Ra, electropolishing protocol, and passivation report. HECHT supplies complete validation packages.
When is an N₂ blanket mandatory for pharmaceutical storage vessels?
A nitrogen (N₂) blanket above the liquid surface is mandatory for: (1) Oxidation-sensitive API that degrades upon contact with oxygen (e.g., vitamin C, many biologics), (2) WFI storage longer than 24 hours (TOC reduction due to microbial growth on oxygen-containing surface), (3) Explosive solvents where vapor concentration above the liquid surface must remain outside explosive limits (ATEX 2014/34/EU). N₂ pressure typically 0.05–0.2 bar overpressure, monitored via pressure switch SIL IEC 61511.
