PTFE bellows, also known as PTFE expansion joints or PTFE convoluted bellows, are flexible and durable components used in piping systems to accommodate thermal expansion, vibration, and movement while maintaining a leak-free seal. PTFE bellows find applications in various industries, including chemical processing, pharmaceutical, oil and gas, power generation, and semiconductor manufacturing. They are commonly used in piping systems, exhaust systems, and equipment where flexibility, vibration absorption, and chemical resistance are required.
PTFE bellows offer exceptional resistance to a wide range of chemicals, acids, solvents, and corrosive substances. They can withstand exposure to aggressive media, making them suitable for use in chemically demanding environments.
PTFE bellows can handle a wide range of temperatures, from cryogenic conditions up to approximately 260°C (500°F).
PTFE bellows are designed with convoluted or corrugated patterns, which provide flexibility and allow for axial, lateral, and angular movement. They can absorb thermal expansion and contraction, vibration, and movement within a piping system, reducing stress on the system and minimizing the risk of damage or leaks.
PTFE has a low coefficient of friction, resulting in smooth movement and minimal energy loss. This property helps to reduce wear, noise, and frictional heat, ensuring efficient operation of the system.
PTFE has a non-stick surface, preventing the adhesion of substances and making the bellows easy to clean and maintain. This property is particularly advantageous in applications where cleanliness is critical.
PTFE bellows are available in different sizes, configurations, and end connections to suit specific application requirements. They can be customized to accommodate different pressures, temperatures, movements, and media compatibility.
