PTFE (Polytetrafluoroethylene) lined flexible metal hose combines the flexibility and strength of a metal hose with the chemical resistance and low friction properties of a PTFE lining. This type of hose is designed for applications involving corrosive or high-purity fluids where traditional metal hoses might not provide sufficient resistance.

1.PTFE Lining: The interior PTFE lining offers excellent chemical resistance to a wide range of corrosive substances, high temperatures, and extreme pH levels, making it suitable for aggressive and high-purity applications.
2.Flexible Metal Outer Layer: The metal outer layer, usually made from stainless steel, provides strength, durability, and protection to the PTFE liner, allowing for flexibility and resistance to external damage.
3.Smooth Flow: The PTFE liner has a low coefficient of friction, ensuring smooth fluid flow and reducing the risk of pressure drops, clogging, and fluid degradation.
4.Temperature and Pressure Resistance: These hoses can withstand high temperatures and pressures, making them versatile for various demanding applications.
PTFE lined flexible metal hoses are widely used in industries such as:
Chemical Processing: Ideal for transporting highly corrosive chemicals and solvents that would degrade standard metal hoses.
Pharmaceutical and Food Industries: Used for transferring high-purity fluids, ensuring no contamination or reaction with the hose material.
Petrochemical Industry: Applied in systems carrying aggressive fluids, ensuring durability and safety in harsh environments.
Cryogenic Applications: Suitable for very low temperature applications due to PTFE's stability under extreme conditions.
Overall, PTFE lined flexible metal hoses are critical components in industries that require a combination of flexibility, durability, and chemical resistance, providing reliable and safe performance in challenging environments.
