Product Overview

Our horizontal chemical storage tank is a high-performance pressure vessel designed for safe, long-term storage of corrosive chemicals, acids, alkalis, solvents, and other industrial media. Built with a carbon steel outer shell lined with PTFE/PFA/PVDF (or available in stainless steel), the tank combines structural strength with exceptional chemical inertness, making it ideal for aggressive process environments.

Available in custom sizes (volume: 1–100 m³), pressure ratings, and nozzle configurations, it meets strict ASME/GB150 standards and supports atmospheric, pressure, and vacuum storage applications. The horizontal design optimizes plant space and simplifies installation, inspection, and maintenance.

Key Features & Advantages

• Easy access for cleaning, inspection, and repairs

Working Principle

The horizontal chemical storage tank operates as a static pressure vessel for the safe containment of industrial media:

The tank is filled with liquid or gaseous chemicals through designated inlet nozzles.

The fluoropolymer lining prevents direct contact between corrosive media and the steel shell, eliminating chemical attack and leakage risks.

Pressure relief valves and vent systems maintain internal pressure within safe limits, preventing overpressure or vacuum conditions.

The horizontal orientation ensures uniform load distribution and simplifies liquid level monitoring, sampling, and draining.

Reinforced saddles support the tank, ensuring stable placement on plant foundations.
