Product Materials of Construction
1. Inner layer: Usually made of stainless steel bellows, this bellows has good flexibility and bending resistance, and at the same time can withstand high pressure.
2. Lining: Using polytetrafluoroethylene (PTFE) as the inner material, PTFE has excellent chemical stability, high temperature resistance and low coefficient of friction, which makes the hose especially suitable for conveying highly corrosive liquids, such as acids, alkalis, etc.
3. Outer layer: Adopt braided metal mesh or steel belt, which increases the durability and protection of the hose, making it able to be used in harsh environments, such as high temperature, high pressure and corrosive media.
The medium for which the product is suitable
PTFE-lined hoses are suitable for use with a variety of specialty media, including:
1. Strong acid and alkali media: Such as sulfuric acid, hydrochloric acid, sodium hydroxide, etc.
2. High-temperature gas and liquid media: Such as steam, hot oil, etc.
3. Organic solvents and corrosive gases: Such as benzene, chlorine, etc.
4. Hygienic grade media: In the pharmaceutical and food processing industries, it is used to convey pure fluids.

Product structure features
The PTFE metal hose lined is mainly composed of a metal layer and a PTFE lining. The metal layer is usually made of stainless steel or copper, which has good mechanical strength and compressive properties, and is able to withstand high pressure and high temperature working environments. PTFE linings, on the other hand, have excellent corrosion resistance and chemical stability, and are resistant to most strong acids, alkalis, and organic solvents, resulting in high fluid purity and transfer efficiency.
Product application field
1. Petrochemical industry: Used to transport various corrosive media, such as acid, alkali, salt, etc.
2. Power industry: Used to transport high-temperature steam and hot water.
3. Pharmaceutical and food industry: Used to convey pure fluids to ensure the quality and safety of products.
