Product Overview
ETFE (Ethylene Tetrafluoroethylene) for pipe refers to pipes that are either lined or coated with ETFE fluoropolymer material, designed specifically for fluid transport applications in harsh environments. As a partially fluorinated copolymer of ethylene and tetrafluoroethylene, ETFE combines the chemical inertness of fluoropolymers with enhanced mechanical strength, making the pipes suitable for handling corrosive, high-temperature, and high-pressure media. Unlike traditional metal pipes or pipes made of other plastics, ETFE for pipe integrates the superior properties of ETFE with the structural stability of base materials (such as carbon steel or stainless steel), providing a safe and durable solution for various industrial fluid transport needs. It is widely used in chemical processing, oil and gas extraction, food and pharmaceutical production, and other fields that demand strict material performance and hygiene standards.
Product Details
What is ETFE for Pipe and Its Core Advantages?
ETFE for pipe is a high-performance fluid transport component that leverages the unique characteristics of ETFE fluoropolymer. Compared to other fluoropolymer pipes like PTFE, FEP, or PVDF pipes, ETFE for pipe stands out with a balanced combination of properties that address key pain points in industrial applications. ETFE itself is a premium engineering fluoropolymer, and when applied to pipes (either as a lining or coating), it inherits the material's excellent corrosion resistance, high-temperature stability, and low friction coefficient, while overcoming the brittleness of PTFE and the lower temperature resistance of PVDF.
Our ETFE for pipe adopts HD-9301 ETFE grade, a specially optimized formulation for pipe lining and coating processes. The HD-9301 grade features a melting point of 250-260°C, a specific gravity of 1.7-1.8 g/ml, and a tensile strength of 29-36 MPa, with an elongation at break of 320-400%. These precise technical parameters ensure that the ETFE layer adheres firmly to the base pipe, maintaining structural integrity even under continuous operation at temperatures up to 180°C. The particle size of HD-9301 is controlled at 50/100 μm, enabling uniform electrostatic spraying during processing, which results in a smooth and consistent ETFE coating/lining with no pinholes or defects-critical for preventing fluid leakage and corrosion of the base pipe.

Performance Comparison with Other Fluoropolymer Pipes
When selecting fluoropolymer pipes for industrial applications, understanding the differences between ETFE, PTFE, FEP, and PVDF is crucial. PTFE pipes offer excellent chemical resistance but are brittle and have low mechanical strength, making them prone to damage during installation and transportation. FEP pipes have good processability but can only be used continuously up to 200°C for short periods and 150°C for long periods, limiting their application in high-temperature scenarios. PVDF pipes are corrosion-resistant but have a lower continuous use temperature (up to 150°C) and are heavier, increasing installation costs.
ETFE for pipe, on the other hand, combines the best of these materials: it has corrosion resistance comparable to PTFE, processability similar to FEP, and higher mechanical strength than both. Its continuous use temperature of 180°C is higher than FEP and PVDF, making it suitable for more demanding high-temperature applications. Additionally, the ETFE layer's excellent adhesion to base metals (such as carbon steel) ensures that the pipe has good structural stability, avoiding the delamination issue that is common with PTFE lined pipes. For industries that require a balance of corrosion resistance, high-temperature performance, and ease of installation, ETFE for pipe is the optimal choice.
Key Applications
Chemical Industry: Used for transporting corrosive chemicals such as acids, alkalis, salts, and organic solvents in chemical plants, fertilizer factories, and pesticide production facilities. The corrosion resistance of ETFE ensures that the pipes do not degrade, preventing chemical leakage and ensuring production safety.
Oil and Gas Industry: Suitable for oil and gas extraction, refining, and transportation processes, where the pipes need to withstand high temperatures (up to 180°C) and high pressures (up to 1.6 MPa). ETFE for pipe resists corrosion from crude oil, natural gas, and associated fluids, extending the service life of the pipeline system.
Food and Pharmaceutical Industry: Used for transporting food ingredients, beverages, and pharmaceutical intermediates. The food-grade ETFE material complies with FDA and EU hygiene standards, ensuring that the transported products are not contaminated. It is also easy to clean, meeting the strict hygiene requirements of these industries.
Water Treatment Industry: Applied in desalination plants and wastewater treatment facilities for transporting corrosive water and treatment chemicals. The ETFE layer resists corrosion from saltwater and chlorine-based disinfectants, ensuring the durability of the pipeline system.

FAQ (Frequently Asked Questions)
Q: What is the difference between ETFE lined pipe and ETFE coated pipe?
A: ETFE lined pipe has a thick ETFE layer (usually 1-5 mm) lining the inner wall of the base pipe, suitable for transporting highly corrosive fluids with high pressure. ETFE coated pipe has a thin ETFE coating (usually 0.5-1 mm) on the inner or outer wall, mainly used for anti-corrosion protection of the pipe surface. We can recommend the appropriate type based on your fluid properties and working pressure.
Q: What is the service life of ETFE for pipe under normal working conditions?
A: Under normal working conditions (continuous temperature ≤180°C, pressure ≤1.6 MPa, and non-strong oxidizing fluids), the service life of our ETFE for pipe is more than 10 years. This is verified by long-term use data from our customers in the chemical and oil industries.
Q: Can ETFE for pipe be used for outdoor applications?
A: Yes. ETFE has excellent UV resistance and weather resistance, so ETFE for pipe can be used outdoors for a long time without degradation. It is widely used in outdoor oil and gas pipelines and water treatment facilities.
