BS 4504 PTFE lined stainless steel wire braided covered flexible metal hose fittings
Product Introduction
PTFE lined metal hose is a composite metal hose whose main feature is that the metal pipe wall is lined with PTFE material inside. This unique construction gives the hose excellent performance, making it suitable for a wide range of applications. As a high-performance polymer, PTFE has excellent high temperature resistance, corrosion resistance, low coefficient of friction and other characteristics. It is these characteristics that make PTFE-lined metal hoses show strong vitality in harsh environments such as high temperature, high pressure, and chemical corrosion.
Product Advantages
1. Corrosion resistance
PTFE material (PTFE) has extremely high corrosion resistance and can operate stably in most corrosive media such as acids, alkalis, and salts. Therefore, PTFE-lined metal hoses have a wide range of application prospects in the field of chemical, pharmaceutical, petroleum and other corrosive media transmission.
2. High temperature resistance
PTFE material has excellent high temperature resistance and can remain stable at temperatures up to 200°C. This makes PTFE-lined metal hoses have high application value in high-temperature occasions, such as heat exchangers, pipelines and other fields in petroleum, chemical industry, aviation and other fields.
3. The coefficient of friction is small
PTFE material has a low coefficient of friction, which makes PTFE-lined hoses have lower energy consumption and lower operating costs when transferring media. In addition, the low coefficient of friction means that PTFE-lined hoses have good self-cleaning properties and are easy to maintain.
4. Security
PTFE-lined metal hose has good safety, and its metal lining can withstand pressure to a certain extent to ensure the safe operation of the pipeline in harsh environments. At the same time, PTFE material itself is non-toxic, tasteless and non-polluting, which meets the environmental protection requirements of China.

Product installation steps
1. Pipeline cutting and processing: Use pipeline cutting tools to ensure that the cutting surface is flat and vertical, remove burrs, and ensure the tightness of the pipeline connection part.
2. Docking method: Use appropriate docking methods, such as welding, flange connection, etc., to ensure that the pipe docking end face is smooth.
3. Fixing and support: Set up pipeline support points and fixtures according to the design requirements to avoid displacement of the pipeline due to vibration or gravity.
4. Sealing treatment: Check the tightness of all connections after installation to avoid leakage problems.
