Stainless Steel PTFE Lined Flanges

Stainless steel PTFE lined flanges are essential component used to improve the safety and efficiency of the piping systems where the effects of corrosion are eminent. These flanges are designed with a PTFE lining that makes them resistant to a host of chemicals that would otherwise compromise the connection due to corrosion. The base is made of stainless steel to give the product durability and strength, while the interior surface is coated with PTFE to reduce friction and fluid absorption.

Features of Stainless steel PTFE lined flanges

Stainless Steel PTFE Lined Flanges are unique products that are developed to provide specific characteristics. Here are the key features:

• Corrosion Resistance: The flanges have a PTFE lining that provides a high level of chemical and abrasive resistance to various chemicals, acids, and alkalis.
• Non-Reactive Surface: PTFE has a very low coefficient of friction and does not react with other chemicals. It is used in applications sensitive to contamination.
• Temperature Resistance: These flanges can operate at high temperatures and are useful in many industrial processes involving hot fluids.
• High Durability: Using stainless steel and PTFE makes these flanges capable of withstanding mechanical forces, pressure and physical abrasion without compromising their durability.
• Low Friction: PTFE has a smooth surface and non-stick characteristic, which minimises contact between the material and the flowing fluid and reduces the buildup of materials that may obstruct the flow of fluids in pipelines.
• Leak-Proof Sealing: PTFE lined flanges offer the best sealing features and are immune to corrosion by aggressive chemicals and gases.
• Easy Maintenance: PTFE material has a non-stick surface, which reduces the chances of material sticking to the flanges, making them easier to clean and maintain than unlined flanges.
• Versatile Applications: These flanges are suitable for use in a range of media, including corrosive and abrasive fluids, and therefore are suitable for use in numerous industries.

These features make stainless steel PTFE lined flanges suitable for applications that require strength and resistance to chemical attack.

Uses of Stainless Steel PTFE Lined Flanges

Stainless steel PTFE lined flanges are applied in various sectors and processes. Here are the key applications: 

• Chemical Processing Plants: SS PTFE-lined flanges are commonly used in chemical industries to handle chemicals, strong acids and aggressive solvents. 
• Pharmaceutical Industry: In the production of drugs, PTFE-lined flanges are employed to avoid contamination and any interaction with the substances being transported. 
• Food and Beverage Industry: These flanges are employed in food processing conduits to convey liquids, juices, and other edible products without any chemical interaction or altering the taste of the product. 
• Oil and Gas Industry: PTFE-lined stainless steel flanges are used in pipelines that convey aggressive gases, crude oil and chemicals.
• Water Treatment Plants: SS PTFE-lined flanges are employed in seawater reverse osmosis plants, sewage treatment plants, and chemical water treatment processes, making them suitable for use in pipelines since they do not wear out easily or allow leakage.
• Petrochemical Industry: These flanges are employed to transfer chemical products under high pressures and elevated temperatures in petrochemical industries.
• Acid Processing: Manufacturing companies that deal with strong acids like sulfuric acid, hydrochloric acid or nitric acid use PTFE lined flanges to avoid the corrosion of metal surface and to enable safe and effective transfer of the dangerous products.
• Pulp and Paper Industry: PTFE lined flanges are used in paper mills to deal with aggressive chemicals such as bleach, chlorine and caustic solutions used in the pulping and paper manufacturing. 

These flanges offer long-lasting and chemical-resistant properties and are hence used in industries where high performance and reliability are expected in harsh conditions.
