As a trusted manufacturer with over 25 years of metal fabrication experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Stainless Steel Water Tank for Pharmaceutical Industry, 304 Grade, Sanitary Welded, Standard Compliant. Engineered for the most demanding cleanroom environments, this tank is built to meet the stringent purification and contamination control requirements of pharmaceutical water systems. Our factory, established in 1998, combines precision craftsmanship with advanced welding technology to deliver a tank that ensures product purity, longevity, and full traceability. Every tank is manufactured under strict quality control, making it a reliable choice for WFI (Water for Injection), purified water, and buffer solution storage.
The core of our design lies in the 304 stainless steel construction, which offers excellent corrosion resistance, easy cleaning, and compatibility with a wide range of pharmaceutical processes. The sanitary welding process eliminates crevices and dead zones, preventing bacterial growth and ensuring smooth, drainable interiors. Our tanks are fully compliant with international standards such as GMP, ASME BPE, and 3A (optional upon request), providing peace of mind for regulatory audits. With an annual export value of US$5-10 million, we supply to pharmaceutical facilities across North America, Europe, Southeast Asia, and beyond.
Key Features & Technical Specifications
- Material Grade: 304 Stainless Steel (ASTM A240) – low carbon content for improved weldability and corrosion resistance.
- Welding Process: Fully automatic TIG welding with orbital pipe welding for consistent, smooth, and sanitary joints. All welds are ground flush and passivated.
- Surface Finish: Interior mirror polish (Ra ≤ 0.4μm) and exterior satin finish (Ra ≤ 0.8μm) – meets cleanroom standards.
- Capacity Range: Customizable from 100 liters to 50,000 liters, with options for manholes, vents, sight glasses, and spray balls.
- Standard Compliance: Designed to meet GMP (Good Manufacturing Practice), ASME BPE, and FDA guidelines (certification available upon request).
- Sanitary Fittings: Tri-clamp connections, CIP/SIP nozzles, and adjustable legs with leveling pads.
- Testing & Inspection: 100% hydrostatic test, dye penetrant test on welds, and surface roughness verification.

Beyond the technical specs, our tank offers significant customer benefits: reduced cleaning time due to seamless interior, lower risk of contamination, and extended service life even under frequent CIP/SIP cycles. The sanitary welded design eliminates threaded connections, ensuring no dead legs or hidden harborage for microorganisms. Furthermore, the tank’s modular construction allows for easy integration into existing piping systems, with optional accessories like level sensors, temperature probes, and pressure gauges.
We understand that the pharmaceutical industry demands absolute traceability. Each tank is delivered with a comprehensive documentation package, including material test certificates, weld maps, passivation records, and hydrostatic test reports. Our factory in Hengshui, Hebei, China, is equipped with a dedicated cleanroom for final assembly and inspection, ensuring that every tank leaves our facility in pristine condition.
With 25 years of manufacturing excellence and an export record of US$5-10 million annually, Anping Boli has earned the trust of pharmaceutical clients worldwide. Our tanks are shipped from major ports (Tianjin, Qingdao, Shanghai, Foshan) with professional packaging to prevent damage during transit. We offer a standard warranty of 12 months and provide technical support for installation and commissioning. For a reliable, compliant, and durable water storage solution, choose our 304 sanitary welded tank.
Frequently Asked Questions
Q1: What certifications does this tank have?
Our tank is designed to comply with GMP and ASME BPE standards. Certificates can be issued by independent third-party inspectors upon request. We do not assume any certification without explicit agreement.
Q2: Can the tank be customized for specific dimensions?
Yes, we offer full customization in diameter, height, wall thickness, and nozzle positions. Please provide your required capacity and footprint, and our engineering team will design accordingly.
Q3: Is the tank suitable for WFI (Water for Injection) storage?
Absolutely. The 304 grade stainless steel, sanitary welding, and mirror polish finish meet the requirements for WFI systems. However, for higher purity demands, we also offer 316L grade as an option.
Q4: What is the lead time for a standard tank?
For standard sizes (1000L – 5000L), the lead time is typically 30-45 days after design approval. Custom tanks may require 45-60 days depending on complexity.
Q5: How is the tank packaged for international shipping?
Each tank is securely wrapped in protective film, placed in a wooden crate, and secured with steel bands. We also provide fumigation certificates for wooden packaging when required.
Q6: Do you provide installation support?
We provide detailed installation drawings and commissioning guidelines. On-site installation support can be arranged at an additional cost, depending on location.
Q7: Can the tank be used for corrosive chemicals?
304 stainless steel has good resistance to many chemicals, but for highly corrosive substances (e.g., chlorides, strong acids), we recommend consulting with our technical team to select the appropriate material (e.g., 316L, duplex).
Q8: What is the warranty period?
We offer a 12-month warranty against manufacturing defects from the date of shipment. Extended warranty options are available upon request.
