Product Slogan
High-transparency weldable FEP tubes: -200℃ to 200℃ operating range, excellent chemical resistance. 500m+ continuous length, ideal for chemical conveying, water treatment & medical use-reliable fluoroplastic solution.
Product Overview
High-Transparency Weldable FEP Tubes are high-performance fluoroplastic tubing manufactured from fully fluorinated ethylene propylene (FEP) resin, a premium member of the fluoropolymer family. Inheriting the core chemical inertness of PTFE tubes, FEP tubes offer superior formability and can be produced in continuous lengths of 500 meters or more, addressing the limitations of traditional fluoroplastic tubing in large-scale applications. Their unique solubility and ductility enable the production of diverse configurations, while features like high transparency, low friction, and weldability make them versatile across industries. Compatible with other high-performance fluoropolymers such as PVDF and ETFE, these FEP tubes serve as critical components for chemical fluid conveying, wire insulation, water treatment, and medical devices, delivering a balance of durability, functionality, and ease of use.

Features (F)
1. Core Material & Structural Advantages: FEP tubes are fabricated from high-purity FEP resin, a fluoropolymer with a fully fluorinated molecular structure similar to PTFE. This structure endows the tubes with exceptional chemical inertness, being resistant to most industrial chemicals, solvents, acids, and bases-eliminating the risk of tube degradation or fluid contamination. Unlike PTFE tubes, FEP resin exhibits excellent solubility and ductility, allowing for seamless extrusion into continuous lengths of 500 meters or longer, and enabling welding at joints for custom system integration.
2. Key Performance Indicators: These FEP tubes boast a wide operating temperature range of -200℃ to 200℃, maintaining structural integrity and performance in extreme hot and cold environments. They feature high transparency (light transmittance ≥ 90%), enabling real-time monitoring of internal fluid flow and condition-critical for chemical processing and medical applications. With a low friction coefficient (≤ 0.04), the tubes ensure smooth fluid conveying with minimal pressure loss, while their tensile strength of ≥ 20MPa guarantees mechanical durability during installation and long-term use.
3. Versatile Configurations & Production Capabilities: Leveraging FEP's formability, we offer FEP tubes in diverse diameters (from 0.5mm to 50mm), wall thicknesses (0.1mm to 5mm), and configurations, including standard straight tubes, heat shrink tubes, and UV spiral tubes for water treatment. The ability to produce continuous lengths of 500 meters or more supports large-scale industrial applications, reducing joint connections and potential leakage points compared to shorter-length tubing options.
4. Industry-Specific Adaptations: For water treatment applications, our FEP UV spiral tubes are engineered with optimized winding structures to maximize UV exposure, ensuring efficient water disinfection. In medical applications, the tubes meet biocompatibility standards (ISO 10993), with smooth inner surfaces to minimize tissue irritation. For chemical conveying, the tubes are designed with uniform wall thickness to ensure consistent pressure resistance and chemical resistance.
Benefits (B)
1. Chemical Processing Industry: Safe & Efficient Conveying: For chemical manufacturers, FEP tubes' chemical inertness ensures the purity of conveyed fluids and prevents tube failure, reducing the risk of costly leaks and environmental hazards. The long continuous lengths and weldability simplify the design of complex conveying systems, improving operational efficiency.
2. Water Treatment Plants: Reliable Disinfection & Durability: FEP UV spiral tubes enable efficient water disinfection by maximizing UV exposure, ensuring the removal of bacteria and contaminants. Their UV resistance and chemical inertness ensure long-term performance in harsh water treatment environments, reducing maintenance frequency and replacement costs.
3. Medical Industry: Safe & Biocompatible Devices: Biocompatible FEP tubes are ideal for catheters and endoscopy equipment, minimizing tissue irritation and ensuring patient safety. Their high transparency allows medical professionals to monitor fluid flow during procedures, improving treatment accuracy.
4. Electronics & Printing Industries: Reliable Insulation & Processing: As wire and cable insulation, FEP tubes' high temperature resistance and electrical insulation properties (dielectric strength ≥ 20kV/mm) ensure reliable performance in electronic devices. As paint conveying rollers in printing machinery, their low friction and chemical resistance prevent paint contamination and ensure uniform application.
Evidence (E)
1. Third-Party Certification & Testing: Our FEP tubes have passed rigorous testing in accordance with international standards, including ISO 9001 quality management system certification and ASTM D3307 (standard specification for FEP tubing). Test results confirm their chemical resistance (resistant to 95% of industrial chemicals), high transparency (light transmittance 92%), and operating temperature range (-200℃ to 200℃). Biocompatibility test reports (ISO 10993) are available for medical-grade FEP tubes.
2. Industrial Water Treatment Project Case: A 50,000 m³/day water treatment plant in Southern China adopted our FEP UV spiral tubes for disinfection. After 24 months of continuous operation, the tubes maintained their structural integrity and UV transmittance (≥ 88%), ensuring a bacteria removal rate of 99.9%. The plant reported a 30% reduction in maintenance costs compared to previous quartz tube solutions, due to FEP's superior durability and UV resistance.
3. Chemical Conveying Customer Testimony: A leading chemical manufacturer stated: "We replaced our PTFE tubes with FEP tubes for conveying corrosive solvents. The weldability and long continuous lengths simplified our system design, reducing leakage points by 60%. The high transparency allows us to monitor fluid flow in real time, improving process safety. We've also seen a 25% reduction in installation and maintenance costs."

FAQ
Q: What is the difference between FEP tubes and PTFE tubes?
A: Both FEP and PTFE tubes offer excellent chemical resistance, but FEP tubes have superior formability, weldability, and transparency. FEP can be produced in long continuous lengths (500m+), while PTFE is more rigid and difficult to weld. FEP also has a lower melting point (260℃) than PTFE (327℃), making it easier to process. For applications requiring formability and visibility, FEP is preferred; for ultra-high temperature applications, PTFE may be more suitable.
Q: Can FEP tubes be used for food and beverage conveying?
A: Yes, our food-grade FEP tubes meet FDA (21 CFR 177.1550) and EU 10/2011 food contact material standards. They are non-toxic, odorless, and do not leach harmful substances into food or beverages, making them ideal for conveying food ingredients, juices, and drinking water.
Q: What is the lead time for bulk orders of FEP tubes?
A: For standard diameter and length FEP tubes, the lead time is 7-12 working days. For custom configurations (special diameter, wall thickness, or length) or large-scale orders (over 10,000 meters), lead time extends to 15-20 working days. We offer expedited production for urgent project needs-contact our team for details.
Q: How should FEP tubes be stored to maintain performance?
A: Store FEP tubes in a clean, dry, and ventilated environment at 5-30℃, away from direct sunlight, high temperatures, and sharp objects. Avoid bending the tubes into small radii or placing heavy objects on them to prevent permanent deformation. The tubes should be kept in their original packaging (plastic film and cartons) to prevent contamination. Proper storage ensures the tubes retain their performance characteristics for up to 2 years.
