Introduction to Stainless Steel Pharmaceutical Storage Tanks

Stainless steel pharmaceutical storage tanks are key equipment used in the pharmaceutical industry for storing, mixing, reacting, or temporarily storing pharmaceutical raw materials, intermediates, and finished liquids. Its design strictly follows international standards such as GMP (Good Manufacturing Practice) and FDA (Food and Drug Administration) to ensure the safety, stability, and hygiene of drug production. With excellent corrosion resistance, ease of cleaning, and long lifespan, stainless steel storage tanks have become the preferred container in the modern pharmaceutical industry.

Core features and advantages:
1. Material selection
. Medical grade stainless steel: Made of high-grade austenitic stainless steel such as 304, 316L, etc., it has strong acid and alkali resistance, oxidation resistance, and can effectively prevent metal ion precipitation and avoid contaminating drugs.
. Surface treatment process: The inner wall is mechanically polished or electrolytically polished, with a surface roughness Ra ≤ 0.4 μ m, achieving a mirror effect, ensuring no residue, easy cleaning, and meeting the requirements of aseptic production.
2. Structural Design
. Sanitary grade structure: The tank body adopts a circular or conical bottom design to avoid dead corners; The weld seam is smooth and meets the ASME BPE standard, eliminating the risk of microbial growth.
. Fully enclosed system: equipped with sanitary grade quick opening manholes, respirators, and CIP (online cleaning)/SIP (online sterilization) interfaces, supporting automated cleaning and sterilization processes.
. Sealing performance: PTFE or silicone sealing rings are used, which are resistant to high temperature and high pressure, ensuring no leakage or cross contamination.
3. Multi functional adaptability
. Customized mixing devices (such as anchor and paddle), heating/cooling jackets, temperature sensors, level gauges, pressure gauges, and other accessories can be made according to process requirements to meet various functions such as mixing, reaction, and constant temperature control.
. Support inert gas (such as nitrogen) protection system to prevent chemical oxidation and deterioration.
Application areas:
. Raw material storage: temporary storage and transportation of intermediates such as solutions, suspensions, extracts, etc.
. Finished drug storage: Aseptic storage of finished products such as injections, oral liquids, and biologics.
. Process water system: storage and distribution of purified water and water for injection (WFI).
. Bioengineering: Temperature controlled storage and mixing of cell culture media and fermentation media.
