Frequently Asked Questions (FAQs)
1. What materials are recommended for ultra-pure water storage vessels?
316L stainless steel with controlled sulfur content is the preferred material for most pharmaceutical and high-purity water storage applications. This material, when properly finished and passivated according to ASME BPE standards, provides optimal corrosion resistance, minimal leaching potential, and excellent cleanability. For exceptionally corrosive environments, we also offer AL-6XN superaustenitic stainless steel options.
2. What surface finish is required for ultra-pure water storage vessels?
For pharmaceutical applications, interior surfaces typically require electropolished finishes with Ra values between 0.2μm and 0.4μm (8-16 μin) to minimize biofilm formation and facilitate cleaning. The specific finish requirements depend on the water grade being stored (PW, WFI, etc.) and applicable regulatory standards like USP <1231> and ISPE Guidelines.
3. How do you prevent microbial growth in ultra-pure water storage vessels?
We incorporate multiple strategies to prevent microbial growth, including sloped bottoms for complete drainage, minimal deadlegs, high-temperature sanitization capabilities, UV or ozone sanitization systems, continuous recirculation designs, and materials/surface finishes that inhibit biofilm formation. Our vessels can be configured with hot storage (maintained at >65°C) or designed for periodic thermal sanitization, depending on your specific requirements.
4. What sanitization methods are compatible with your vessels?
Our vessels are designed to accommodate various sanitization methods including thermal sanitization (hot water or steam), chemical sanitization, and advanced techniques like ozone or UV light. The specific design features vary based on the chosen sanitization strategy, with considerations for temperature resistance, material compatibility, and integration with sanitization systems.
5. What regulatory requirements apply to ultra-pure water storage vessels?
Ultra-pure water storage vessels must comply with multiple regulatory frameworks, including FDA cGMP regulations, pharmacopeial standards (USP, EP, JP), and industry guidelines like the ISPE Baseline Guide: Water and Steam Systems. Our vessels are designed and fabricated to meet or exceed these standards, with comprehensive documentation to support regulatory filings.
6. How do you address rouging in stainless steel water storage vessels?
We employ multiple strategies to minimize rouging, including proper material selection, controlled welding procedures, thorough passivation, electropolishing, and design features that facilitate periodic maintenance and inspection. Additionally, our vessels can be designed to accommodate derouging processes when needed, with appropriate access points and material compatibility considerations.
7. What instrumentation is recommended for ultra-pure water storage vessels?
Typical instrumentation includes sanitary temperature sensors (RTDs), level transmitters, pressure sensors, and potentially conductivity or TOC analyzers for water quality monitoring. All instrumentation is selected for compatibility with ultra-pure water applications, with sanitary connections, minimal deadlegs, and materials that prevent contamination of the stored water.
8. How are your vessels designed to maintain water temperature during storage?
For hot storage systems, our vessels incorporate efficient jacketing designs, high-quality insulation packages, and precise temperature control systems to maintain consistent temperatures throughout the storage volume. For ambient storage systems, we can provide jacketing for sanitization cycles while minimizing heat gain during normal operation through appropriate insulation.
9. What documentation is provided with ultra-pure water storage vessels?
We provide comprehensive documentation packages including design specifications, material certifications, welding procedures and qualifications, surface finish reports, pressure test records, passivation certificates, and other documentation required for regulatory compliance and validation activities. This documentation supports installation qualification, operational qualification, and performance qualification protocols.
10. What is the typical lead time for a custom ultra-pure water storage vessel?
Lead times vary based on vessel complexity, size, and current production schedule. A typical custom ultra-pure water storage vessel may require 10-16 weeks from order to delivery, but we work closely with clients to develop realistic project timelines that align with their operational needs and facility integration requirements.
