Mild Steel PTFE Lined Flanges

Mild Steel PTFE-lined flanges are industrial flanges manufactured from mild steel with an outer layer of polytetrafluoroethylene (PTFE), a chemically resistant and highly wear-resistant polymer. These flanges are made from mild steel that is strong and cheap and PTFE, which is known to be more corrosion resistant than steel, in cases where the metal part of the flange is likely to come into contact with aggressive chemicals or corrosive substances. The PTFE lining helps to prevent the mild steel from coming into direct contact with the fluid being transported while at the same time providing a strong bond in the pipeline. These flanges are ideal for use in chemical processing, pharmaceutical, water treatment, and food industries where mechanical strength and chemical resistance are needed.

Features of Mild Steel PTFE Lined Flanges

These flexible Mild Steel PTFE Lined Flanges offer numerous benefits for industrial applications.

• Corrosion Resistance: The PTFE lining also protects the mild steel flanges against corrosive chemicals, acids and solvents.
• Cost-Effective: Compared to stainless steel or alloy steel, mild steel is relatively cheaper. Thus, PTFE-lined mild steel flanges are a cost-effective solution for industries requiring chemical protection.
• Durability: Mild steel has good mechanical strength and durability, which enable the flanges to serve moderate to high-pressure systems without deforming.
• Chemical Inertness: PTFE does not react with most chemicals and can, therefore, be used in highly corrosive and aggressive chemical surroundings with no sign of degradation.
• Temperature Resistance: The PTFE lining offers good thermal stability over a broad range of temperatures, ensuring the flange’s suitability for both high- and low-temperature services.
• Non-Stick Surface: PTFE does not stick to substances and chemicals and, hence, does not accumulate on the flange surface to cause blockage.
• Low Maintenance: Using PTFE lining also means it does not require frequent maintenance and cleaning since it is resistant to corrosion, scaling and chemical deposits.
• Improved Sealing: The PTFE lining provides a very close fit and no leakage, which is important when handling corrosive or toxic materials.
• Versatility: Mild steel PTFE lined flanges are used in chemical processing, food processing, pharmaceuticals, plastics, water treatment, and many other industries.
• Resistance to Abrasion: The PTFE lining shields the mild steel from aggressive or abrasive material contact, thus enhancing the flanges’ durability.

Mild Steel PTFE Lined Flanges offer several advantages that make them suitable for industrial and commercial applications.

Applications of Mild Steel PTFE Lined Flanges

Mild Steel PTFE Lined Flanges are preferred for various industrial applications.

• Chemical Processing: Mild Steel PTFE-lined flanges are common in chemical plants and refineries, where they are used to transport aggressive chemicals, acids, and solvents and where corrosion protection and system reliability are critical.
• Pharmaceutical Industry: In the manufacture of pharmaceuticals, PTFE-lined flanges make it possible to use mild steel, which would otherwise be affected by the chemicals used in the production of drugs. At the same time, the purity of the drugs is maintained.
• Water Treatment: Mild Steel PTFE-lined flanges are applied in a water treatment plant for the pipe system that transports highly corrosive medium like chlorine, sulfuric acid, and other chemicals used in water treatment.
• Food and Beverage Industry: PTFE-lined flanges are used in food processing plants to convey food-grade chemicals and fluids while avoiding contamination and meeting food industry standards.
• Oil and Gas: Used in the oil and gas industry for pipeline systems where the fluids or gases are corrosive or where long-term protection from the environment is required.
• Pulp and Paper Industry: In paper mills, these flanges are used in the chemical treatment of wood and paper, shielding the piping systems from aggressive chemicals.
• Mining Industry: Mild Steel PTFE-lined flanges are used in mining industries to convey chemical slurries and aggressive materials, where wear and chemical corrosion are critical to the equipment's performance.
• Power Generation: PTFE lined flanges are used in power plants to transport fluids and gases that could otherwise cause corrosion of pipelines thereby affecting the efficiency and safety of power generation equipment.
• Automotive and Aerospace: PTFE lined mild steel flanges are used where chemical resistance and strength are needed for fuel handling and exhaust systems for high performance cars and aircraft.

Mild Steel PTFE Lined Flanges are applied across various industries due to their valuable features, which make them versatile.
