PTFE Flange Cover / PVC Flange Cover
PTFE Flange Cover and PVC Flange Cover are professional protective accessories designed to shield flange connections from external damage, contamination, and corrosion, widely used in industrial pipelines, chemical equipment, water treatment systems, and other fields. These two types of flange covers are tailored to different working environments, providing targeted protection solutions to extend the service life of flange connections and ensure safe and stable operation of equipment.
PTFE Flange Cover
Made of high-quality PTFE (polytetrafluoroethylene) material, our PTFE Flange Cover boasts exceptional chemical inertness, high-temperature resistance, and non-stick properties, making it ideal for harsh industrial environments. It can withstand continuous operating temperatures ranging from -70°C to +260°C, resisting corrosion from most acids, alkalis, solvents, and corrosive gases—perfect for flange connections in chemical, pharmaceutical, and petroleum processing industries.
The PTFE flange cover features a smooth, non-stick surface that prevents adhesion of dust, dirt, and chemical residues, ensuring easy cleaning and maintenance. It is designed with a snug, secure fit, adapting to various flange sizes (from DN15 to DN600) and connection types (RF, FF, RTJ). The durable PTFE material is wear-resistant, tear-resistant, and not easy to age, providing long-term reliable protection for flange connections and avoiding leaks caused by external damage.
PVC Flange Cover
Crafted from high-quality PVC (polyvinyl chloride) material, our PVC Flange Cover is a cost-effective, lightweight protective solution suitable for general industrial and civil pipeline systems. It offers excellent waterproof, dustproof, and anti-aging properties, effectively preventing moisture, dust, and debris from entering flange connections, thus avoiding rust and corrosion of flange surfaces and bolts.
With good flexibility and ductility, the PVC flange cover is easy to install and disassemble, fitting tightly on flange surfaces without affecting pipeline maintenance. It is resistant to general chemicals and has a stable performance in normal temperature environments (0°C to +60°C), making it widely applicable to water supply and drainage, HVAC, and general industrial pipelines. Available in various sizes and colors, it can be customized according to specific flange specifications and application needs.
Both our PTFE and PVC flange covers undergo strict quality control procedures, ensuring consistent thickness, stable performance, and reliable protection. They are designed to meet international industrial standards, providing a practical and efficient solution for protecting flange connections. Whether you need high-temperature and corrosion-resistant protection or cost-effective general protection, we have the right flange cover to meet your requirements.
