Introduction to PTFE Spray Coating Vessel Tanks

PTFE Spray Coating Vessel Tanks leverage the cutting-edge rotational sintering process combined with high-performance materials to forge tanks that stand at the forefront of industrial storage solutions. These tanks are meticulously designed with an integrated PTFE lining, renowned for its unparalleled chemical resistance and durability, making them perfectly suited to meet the rigorous demands of diverse industrial applications. The essence of using advanced lining technologies like PTFE lies in its ability to provide a chemically inert storage environment, thereby preserving the integrity and purity of stored substances. This innovative approach to tank design ensures that industries dealing with corrosive chemicals, high-purity substances, or challenging operational conditions have access to storage solutions that are not only reliable but also tailored to enhance operational efficiency and safety.

Detailed Description

The fabrication of PTFE Spray Coating Vessel Tanks employs a novel dual-axis rotational molding process that ensures a flawless and robust bond between the PTFE lining and the steel substrate. This begins with the meticulous preparation of the steel surface, including sandblasting to remove impurities and create an ideal surface for bonding. Following this, a specialized adhesive is applied to both the tank surface and the PTFE material, prepared for its integration. The PTFE liner is then positioned within the tank, and the entire assembly is subjected to a controlled rotational motion along two axes. This movement, combined with precise temperature control, allows the PTFE to sinter perfectly to the steel, creating a seamless, uniform lining devoid of cracks, pores, or potential weak points. The result is a tank with a non-permeable, highly resistant inner surface that maintains its integrity even under extreme conditions.

Key Features

Corrosion Resistance: The PTFE lining provides unmatched stability across a broad pH spectrum, from highly acidic to basic environments. This makes the tanks ideally suited for storing a wide range of corrosive chemicals without risk of degradation or contamination.

Permeation Resistance: The molecular structure of PTFE forms an effective barrier against small molecule gases such as oxygen, carbon dioxide, and chlorine. This feature is crucial for maintaining the purity of sensitive substances and preventing the ingress of contaminants.

Surface Smoothness: The inner surface of the tank is exceptionally smooth and resembles enamel in appearance. This characteristic significantly reduces friction and prevents the adhesion of materials, making the tanks easier to clean and less susceptible to scaling.

Structural Advantages: The design of the tanks eliminates the need for large flanges, relying instead on accessible manholes for inspection and maintenance. This simplification not only enhances the tank's structural integrity but also facilitates easier installation and servicing.

Advantages Of Our PTFE Spray Coating Vessel Tanks

The PTFE Spray Coating Vessel Tanks offer a multitude of advantages that cater to the rigorous demands of various industrial sectors, including the photovoltaic industry, where purity and durability are paramount.

High Purity: These tanks are engineered to meet the exacting standards of industries requiring ultra-pure storage solutions. The inert nature of PTFE ensures no contaminants are leached into the stored substances, making these tanks ideal for the photovoltaic sector and similar applications demanding uncompromised purity.

Long Service Life: Designed with longevity in mind, these tanks are expected to serve reliably for a decade or more. The robust PTFE lining resists degradation even under continuous use, minimizing the need for frequent replacements and thereby reducing long-term operational costs.

Impact Resistance: The structural integrity of these tanks is maintained even under adverse conditions, thanks to the high impact resistance of the PTFE lining. This ensures that the tanks can withstand physical shocks without compromising their performance or the safety of the stored materials.

Customizable Form Factors: Recognizing the diverse needs of industrial operations, these tanks are available in various configurations, including vertical, horizontal, and transportable options. This flexibility allows for tailored storage solutions to fit specific spatial and operational requirements.


Tank Shell Materials: The shell can be fabricated from a variety of materials, offering a range of mechanical properties and corrosion resistances. Options include durable carbon steel, corrosion-resistant stainless steel 304/316L, highly durable titanium alloy, and robust duplex stainless steel 2205.

Lining Materials: While PTFE is the primary choice for lining due to its exceptional chemical resistance and purity, alternative materials such as PE, PO, ETFE, and PFA are available for specific applications that require different material properties.

Sealing Gaskets: To ensure airtight and leak-proof storage, sealing gaskets made from PTFE or rubber-coated PTFE are used, providing an effective seal that maintains the tank's integrity across a wide range of temperatures and pressures.

Fasteners: The tanks are assembled using high-quality fasteners, including galvanized bolts for standard applications, stainless steel bolts for enhanced corrosion resistance, and fluorine-lined bolts for the highest level of chemical resistance.


Pressure Balancing: To maintain optimal internal conditions, nitrogen sealing devices, breather valves, and flame arresters are available, ensuring the safe storage of volatile or sensitive materials by regulating the tank's internal pressure and preventing ignition of flammable gases.

Material Handling: For the controlled transfer of materials into and out of the tank, fluorine-lined ball valves are offered in manual, electric, and pneumatic variants, alongside diaphragm pumps, ensuring compatibility with the tank's lining and the materials being stored.

Measurement Devices: Accurate dosing and transfer of liquids are facilitated by PP and PVDF metering pumps, which are chosen for their chemical compatibility and precise operation.

Observation Devices: Monitoring the contents of the tank is made easy with fluorine-lined sight glasses and level gauges, providing clear visibility and accurate level measurement without risking contamination or reaction with the stored materials.

Applications of Fluorine-Lined Metering Tanks

PTFE Spray Coating Vessel Tanks are essential in a multitude of industries due to their superior chemical resistance and purity retention capabilities. These tanks find applications in:

Chemical Processing: Ideal for storing and handling aggressive chemicals, including strong acids and bases, without risk of corrosion or material degradation, thus ensuring process continuity and safety.

Pharmaceuticals: Used in the production and storage of pharmaceutical ingredients where material purity is critical. The non-reactive nature of PTFE prevents contamination and ensures compliance with stringent industry standards.

Water Treatment: Crucial for containing chemicals used in water purification processes, such as chlorine and fluorides. Their corrosion resistance ensures longevity even with continuous exposure to harsh substances.

Semiconductor Manufacturing: Supports the storage of high-purity solvents and acids used in the cleaning and etching processes, where even minor contamination can compromise the manufacturing outcomes.
