PFA Lined Tanks material and installation method
 

Types of lining material

PFA

FA/
PFA

PFA is a fluororesin that can be melted and molded. It is similar to PTFE in that it has resistance against almost all pharmaceuticals, but compared to PTFE, it has excellent strength at high temperatures and compressive creep resistance. It is widely used for tanks at chemical plants, oil plants, pharmaceutical manufacturing plants, and semiconductor plants. There are two types: “FA”, with brown pigment added for chemical plants and general industries, and “PFA”, a colorless material for high-purity chemicals that are adverse to eluted metals.

PFA－HG

A PFA uses New-PFA with little fluorine ion elusion for semiconductor applications as its raw material and has a smooth surface. Its smooth surface means it can be cleaned more quickly. As PFA－HG has about half the gas permeation of PFA, it reduces the contamination of high-purity liquid medicines from environmental stress cracks (nozzles and welded parts), reductions in adhesive strength, and reverse osmosis during long-term use. PFA－HG is suitable for use in tanks for semiconductor production that has strict cleanliness requirements.

PTFE

PTFE is welded with PFA because it cannot be used for welding and molding due to its high melt viscosity and it cannot be welded with the same material.

Tank Preparation

The outer metal tank (steel, etc.) is cleaned and prepared to ensure good adhesion, as discussed in the context of rubber lining.

 

Liner Fabrication

PFA sheets are either molded into complex shapes (like tank heads) or used as flat sheets.

 

Liner Attachment (Molding/Vacuum)
Transfer Molding/Injection Molding: PFA is molded into intricate shapes, preventing defects like pinholes and ensuring a perfect fit, notes the Bueno Group.

Vacuum Attachment: Sheets are pressed onto the tank surface by removing air, creating a strong, even bond without damage, according to Valqua.

Seam Welding (Fusion Welding): Sheets are joined using PFA welding techniques, creating smooth, strong seams that eliminate gaps, preventing contamination and improving structural integrity over traditional air welds, says GMM Pfaudler.

Nozzle/Fittings Installation: Nozzles and other components are attached, often by fusion welding, to maintain purity and prevent leaks, as detailed by GMM Pfaudler.

Testing & Curing: The lined tank undergoes rigorous spark testing (high voltage) and visual inspection to detect any pinholes or defects, ensuring it meets purity standards, notes Alfsen og Gunderson (AG).

Chemical Storage

Chemical manufacturing and processing facilities rely heavily on PFA Lined Tanks due to their ability to safely contain aggressive reagents without degradation or contamination.

 

Food and Beverage Industry

In food processing, maintaining hygiene and preventing chemical interactions is critical. PFA Lined Tanks offer a safe, FDA-compliant solution for storing acidic food products and processing additives that could otherwise corrode standard containers or leach harmful substances.

Water and Wastewater Treatment

Water treatment plants use a variety of aggressive chemicals to disinfect, coagulate, and balance pH levels. PFA Lined Tanks are essential for handling these substances safely and efficiently, especially in municipal and industrial treatment systems.

 

Pharmaceutical Manufacturing

The pharmaceutical industry demands ultra-pure, contamination-free environments for drug synthesis and formulation. PFA Lined Tanks meet these stringent requirements by offering inert storage for sensitive reagents, solvents, and intermediates.

FAQ

 

Q: What is the process of PFA lining?

A: The PFA liner is made using transfer molding and injection molding. This method prevents pinholes, cracks, swelling, degradation, and ablation. The Dovetail design enables the PFA liner to firmly attach to the valve body, preventing possible peeling, distortion, and shifting. Double sealing valve body design.

Q: What is the purpose of a tank lining?

A: What is a Tank Lining? A tank lining is applied to a tank to protect the substrate material from a chemical attack. An exceptional tank lining creates an impermeable barrier, fully adheres to the substrate, seals all gaps, provides the most cost-effective corrosion protection, and prevents costly hiccups.

Q: What is the difference between PFA and PTFE lining?

A: PFA has very similar properties to PTFE, though the biggest difference between PTFE and PFA is that PFA is melt-processed. This is accomplished through conventional injection molding as well as screw extrusion techniques. PTFE is popularly used as a non-stick coating for pans and many modern items of cookware.

Q: What is the temperature of PFA lining?

A: The PFA lining can be used up to an operation temperature of 260 °C and is showing an excellent chemical resistance against condensation medias like H2SO4, HCl and HF, which are typically present in power plant applications.
