Shijiazhuang Enric Gas Equipment Co., Ltd. delivers high-performance caustic storage tanks designed for sodium hydroxide (NaOH), potassium hydroxide (KOH), and other corrosive chemicals. With 50+ years of expertise, ASME/DOT/CE certifications, and a global footprint in 40+ countries, we provide OEM/ODM designs, fast delivery, and competitive pricing—direct from China’s leading pressure vessel manufacturer.
Our tanks solve corrosion risks, regulatory hurdles, and long lead times—so you get reliable, compliant storage without compromising on quality or cost.
Storing caustic soda (NaOH), potassium hydroxide (KOH), or sulfuric acid isn’t just about containment—it’s about safety, longevity, and compliance. Here’s what keeps purchasing managers and technical directors up at night:
Standard carbon steel tanks fail within 2-3 years when exposed to high-concentration caustic solutions. According to industrial corrosion studies, 30% of chemical storage failures stem from incompatible material selection. HDPE, FRP, or stainless steel (316L/904L) are non-negotiable for long-term integrity.
From OSHA 1910.110 (US) to SEVESO III (EU) and GB 150 (China), caustic storage tanks must meet pressure, emissions, and secondary containment standards. 40% of industrial accidents in chemical storage are linked to non-compliant designs (IEA Global Hydrogen Review 2024).
European or US-manufactured tanks often come with 20-30% premiums and 6-12 month lead times. The Fortune Business Insights 2025 report highlights that Asia-Pacific suppliers (like Shijiazhuang Enric) now dominate cost-efficient, high-quality pressure vessel manufacturing.
With 5 decades of specialization in high-pressure chemical storage, we’ve engineered tanks that outperform competitors on durability, compliance, and value.
