PTFE Lined Metal Hose

Structure and Materials

A PTFE-lined metal hose consists of two main parts:

1. Metal Outer Layer: Typically made of stainless steel, the metal exterior provides strength, durability, and resistance to mechanical wear. It protects the PTFE lining from physical damage and supports the hose in high-pressure environments.
2. PTFE Inner Lining: The inner lining is made from high-quality PTFE, which is known for its superior chemical resistance, high-temperature tolerance, and low friction. The PTFE lining ensures the safe transport of highly corrosive, reactive, or sticky materials without the risk of contamination or degradation.

The hose is often reinforced with additional metal braids or external wraps to provide extra support and prevent kinking or bursting.

Advantages

The PTFE-lined metal hose offers several advantages over traditional rubber or plastic hoses:

Enhanced Chemical and Temperature Resistance: The combination of PTFE and metal ensures the hose can handle a broader range of chemicals and extreme temperatures.

ong Service Life: The durable design reduces maintenance and replacement costs, offering a longer operational life.

Safety and Reliability: The PTFE lining prevents contamination and leaks, ensuring the safe transfer of hazardous materials.

Improved Flow Efficiency: The smooth interior reduces friction, helping improve the flow rate and energy efficiency of fluid transport.

Key Features

1.  
2. 1. Chemical Resistance: PTFE is inert and highly resistant to a wide range of chemicals, acids, alkalis, and solvents, making PTFE-lined hoses perfect for transferring hazardous or aggressive substances.
3. 
   2. Temperature Resistance: PTFE can withstand temperatures ranging from -200°C to +260°C, making it suitable for both cryogenic and high-temperature applications.
4. 
   3. Flexibility and Durability: The metal exterior provides strength and flexibility, allowing the hose to bend and adapt to complex installation layouts without compromising its performance.
5. 
   4. Smooth Internal Surface: The PTFE lining provides a smooth surface that reduces friction, minimizes material buildup, and enhances flow rates.
6. 
   5. Leak Prevention: The robust construction and seamless PTFE lining ensure no leakage, even when handling pressurized or hazardous media.

 

PTFE-lined metal hoses are used in a wide variety of industries, including:
- Chemical Processing:For safely transporting aggressive chemicals, acids, and solvents.
- Pharmaceuticals: In sterile and sanitary applications, such as transferring pharmaceutical ingredients or bioprocessing fluids.
- Food and Beverage: For transferring food-grade liquids, oils, and gases without contamination.
- Petrochemicals and Oil & Gas: For transporting crude oil, natural gas, or byproducts with high-temperature and chemical demands.
- Cryogenic Applications: For handling liquefied gases and cryogenic fluids in extreme low-temperature conditions.

PTFE-lined metal hoses provide a highly versatile and reliable solution for transferring aggressive, hazardous, or temperature-sensitive media.

Their combination of chemical resistance, durability, and flexibility makes them ideal for demanding applications in various industries.

By incorporating PTFE-lined metal hoses into their operations, companies can enhance the safety, efficiency, and longevity of their systems, ensuring smoother and more reliable material handling.
