Advantages of PTFE Lined Tanks
 

Chemical Resistance

As PTFE is highly resistant to a wide range of chemicals, acids, and bases. This makes TEFLON-lined tanks suitable for storing corrosive substances.

Non-Stick Properties

TEFLON has excellent non-stick properties, which means that substances stored in the tank are less likely to adhere to the tank walls. This makes the tanks easier to clean.

Temperature Resistance

PTFE has a high melting point and can withstand a wide range of temperatures. TEFLON-lined tanks can be used for both high and low-temperature applications.

Durability

PTFE is known for its durability and long lifespan. Our TEFLON-lined tanks are designed to withstand the harsh conditions associated with storing aggressive chemicals.

Inert Material

PTFE is considered an inert material, meaning it does not react with most chemicals. This inertness is particularly important when storing sensitive or reactive substances.

Types of PTFE Lined Tanks
 
PTFE Lined Filter Housing
 

PTFE-Lined Storage Tanks

Designed for long-term containment of corrosive liquids such as acids, alkalis, and solvents. These tanks feature a rigid outer shell (often steel-reinforced) with a seamless PTFE lining that prevents chemical interaction with the tank structure.

 

PTFE-Lined Mixer Tanks

Engineered for blending and agitating corrosive solutions, these tanks integrate PTFE linings with specialized mixing systems (impellers, agitators). The lining protects both the tank walls and mechanical components from erosion and chemical attack.

PTFE Lined Reactors
PTFE Lined ISO Tanks
 

PTFE-Lined Transport Tanks

Built for the safe movement of hazardous and corrosive liquids by road, rail, or ship. These mobile tanks combine impact-resistant exteriors with full PTFE linings to prevent leaks, reactions, and environmental contamination during transit.

 

PTFE-Lined Pressure Tanks

Designed to operate under elevated internal pressure while containing corrosive media. These tanks use reinforced shells and thick PTFE linings to withstand both mechanical stress and chemical exposure, commonly used in closed-loop systems and high-pressure reactors.

Maintenance of PTFE Lined Tanks

Regular Inspection: Visually inspect the interior and exterior of the tank periodically for signs of liner damage such as cracks, blisters, discoloration, or delamination. Pay special attention to weld seams, nozzles, and flange areas where stress concentrations occur.

 

Proper Cleaning: Drain the tank completely before cleaning. Use warm water and a mild, non-abrasive detergent to clean the interior. Avoid wire brushes, scrapers, or abrasive pads that could scratch or puncture the PTFE surface.

 

Stain Removal: For stubborn residues, soak the tank with a mixture of water and white vinegar or a baking soda solution. Gently scrub with a soft nylon brush or sponge. Never use chlorine-based cleaners or strong solvents unless compatibility is confirmed.

 

Rinsing Protocol: After cleaning, rinse thoroughly with deionized or clean water to remove all traces of cleaning agents, especially important in high-purity applications.

 

Handling & Storage: When not in use, store the tank in a dry, cool environment away from direct sunlight and ozone sources (e.g., electric motors), which can degrade PTFE over time.

Uses of PTFE Lined Tanks
 

Chemical Processing and Storage
Chemical plants rely heavily on PTFE lined tanks to store aggressive acids, bases, and solvents. These tanks prevent corrosion, reducing maintenance costs and downtime. For example, in the production of specialty chemicals, PTFE lined tanks ensure the integrity of reactive substances, leading to higher yields and safety.

 

Pharmaceutical Manufacturing
In pharma, purity and contamination control are paramount. PTFE lined tanks are used for mixing, storing, and transporting active pharmaceutical ingredients (APIs). Their inert surface prevents contamination and facilitates cleaning, supporting compliance with Good Manufacturing Practices (GMP).

 

Food and Beverage Industry
Food-grade PTFE lined tanks are used for storing ingredients like acids, flavorings, and syrups. Their non-stick surface minimizes residue buildup, simplifying cleaning and reducing cross-contamination risks.

 

Water Treatment and Desalination
PTFE lined tanks are crucial in water treatment plants, especially for handling corrosive chemicals used in purification processes. Their corrosion resistance ensures longevity despite exposure to chlorinated or saline water. This use-case is expanding globally, particularly in regions facing water quality challenges.

 

Petrochemical and Refining
Refineries use PTFE lined tanks to store and process highly corrosive hydrocarbons and acids. Their durability under extreme conditions minimizes downtime and safety risks. The trend toward safer, more sustainable refining processes is boosting demand for PTFE lined tanks in this sector.

 

 

FAQ

 

Q: What is a PTFE-lined storage tank?

A: A PTFE-lined storage tank is a storage tank whose inner wall is coated with polytetrafluoroethylene (PTFE) material. This lining has extremely high corrosion resistance and chemical stability, enabling the storage and transportation of various highly corrosive chemicals, including strong acids, strong alkalis, and organic solvents.

Q: How to maintain a PTFE-lined storage tank?

A: Maintaining a PTFE-lined storage tank is relatively simple, mainly including the following aspects:
Regular inspection: Regularly inspect the integrity of the lining to ensure there are no signs of damage or aging.
Cleaning and maintenance: Use appropriate chemical cleaners when cleaning, avoiding the use of strong acids or alkalis that will damage the PTFE lining.
Avoid impacts and scratches: Because the PTFE lining is relatively soft, avoid impacts or scratches to the lining surface with hard objects to ensure it maintains good performance over a long period.

Q: Is the cost of a PTFE-lined storage tank high?

A: The cost of a PTFE-lined storage tank is relatively high because the PTFE material itself is expensive and the processing technology is complex. However, due to its excellent corrosion resistance and durability, PTFE-lined storage tanks can save a lot of maintenance and replacement costs in the long run. Therefore, from a long-term economic perspective, PTFE-lined storage tanks are an option with a high return on investment.

Q: What are the limitations of PTFE?

A: Limitations of PTFE: Low tensile yield strength and modulus (when compared to PEEK, PPS and LCP) High wear behaviour in unfilled state. Not weldable. Sensitivity to creep and abrasion.
