PTFE lined storage tank 04

Product Overview

A steel-lined PTFE storage tank is a high-performance anti-corrosion container, made of a carbon steel or stainless steel shell lined with polytetrafluoroethylene (PTFE, commonly known as 'Teflon'). It combines the strength of a metal structure with the extreme corrosion resistance of PTFE, specifically designed for storing strong acids, strong alkalis, organic solvents, and high-purity chemical media, making it an ideal choice for chemical, pharmaceutical, electroplating, and other industries.

Product Features

Comprehensive Corrosion Resistance

PTFE lining can resist over 98% of chemical media (such as concentrated sulfuric acid, hydrochloric acid, hydrofluoric acid, organic solvents, etc.), preventing corrosion of the metal shell.

Wide Temperature Range

Operating temperature: -50℃ to +200℃ (short-term up to 250℃), meeting the needs of high or low temperature conditions.

High Cleanliness and Anti-Adhesion

PTFE surface is smooth, non-stick to materials, easy to clean, conforms to GMP and FDA standards, suitable for pharmaceutical and food-grade storage.

High-Strength Structure

Metal shell (Q235B/304/316L) provides excellent pressure resistance and mechanical impact resistance, supporting customized reinforcement designs.

Long Lifespan and Economy

Compared to FRP and plastic storage tanks, it is more resistant to aging, with a service life of 10-15 years, resulting in lower overall cost.

Application Areas

Chemical Industry : Storage of corrosive liquids such as hydrochloric acid, sulfuric acid, nitric acid, and mixed acids.

Environmental Engineering : Transfer or treatment of waste acid and waste alkali solutions.

Electroplating/Electronics : Storage of electrolytes and high-purity chemical reagents.

Pharmaceutical/Food : Clean storage of high-purity solvents and active pharmaceutical ingredients.

Structure Types

Molded Lined Storage Tank

PTFE powder is high-temperature sintered after molding, resulting in a dense, non-porous lining, suitable for small to medium storage tanks (1m³～30m³).

Sheet Lined Storage Tank

PTFE sheets are welded and then lined on the inner wall of the tank, suitable for large storage tanks (above 30m³) or on-site lining construction.

Loose Lined Storage Tank

The PTFE inner liner loosely fits the metal shell, low cost but weaker negative pressure resistance, requires reinforced support.

Technical Parameters

Capacity Range : 0.1m³～100m³ (supports non-standard customization).

Design Pressure : Atmospheric pressure～0.4MPa (negative pressure requires special design).

Optional Accessories ：

Manhole, level gauge, thermometer, agitator interface (requires pre-lining with PTFE).

Heating/cooling jacket (steam, thermal oil circulation).
