Features of 1. PTFE bellows
PTFE bellows exhibit unmatched chemical stability. The tube wall made of polytetrafluoroethylene (PTFE) is inert to almost all chemicals and will not react with acids, alkalis, solvents, oxidants, etc., ensuring long-term service in extremely corrosive environments.
The excellent sealing and lubrication of PTFE bellows provide double protection for fluid delivery. The inner wall of the PTFE bellows is smooth and has a low coefficient of friction, which can effectively reduce fluid resistance, reduce energy consumption, and avoid blockage caused by material adhesion. In addition, its excellent electrical insulation properties make it suitable for use in electrified environments.
In terms of structural design, PTFE bellows has a unique corrugated structure, which gives it good flexibility and bendability, and can easily cope with the complex layout and dynamic stress in the pipeline system. The design with flat heads at both ends simplifies the installation steps, and can be matched with various connection methods such as flange, oil, thread, etc. to realize fast and convenient system integration. Some models can also be customized flanges, and even external steel wires to enhance mechanical strength and adapt to high-pressure or large-scale applications.
2. the scope of use of PTFE bellows
PTFE bellows are widely used in chemical industry, machinery and other industries with strict requirements on pipe performance. In the chemical industry, it is often used to transport high purity reagents, corrosive media and to participate in heat exchange, steam piping and other key processes. In mechanical engineering, its high wear resistance and low friction characteristics make it an ideal choice for hydraulic systems and pneumatic equipment.
3. product specifications and customized services
PTFE corrugated pipe product specifications, covering different inner diameter, wall thickness, length and corrugated spacing, to meet the needs of different flow, pressure and installation space. At the same time, manufacturers usually have the ability to customize according to customer needs, whether it is a special size, connection method or additional functions (such as additional compression reinforcement), can be customized to ensure the perfect fit with the project site conditions.
Typical use of 4. PTFE bellows
Liquid crystal manufacturing equipment: In the precision liquid crystal manufacturing process, PTFE bellows can effectively isolate harmful substances, protect equipment from corrosion, and ensure the stability of the production process and product quality.
Single-end light-emitting single-core fiber tube: As an optical fiber protective sleeve, PTFE bellows has high transparency, low refractive index and no pollution characteristics to help maintain the purity and efficiency of optical signal transmission.
Heat exchanger, steam piping: In high temperature and high pressure environment, the heat resistance, pressure resistance and corrosion resistance of PTFE bellows ensure the long-term stable operation of the heat exchange system.
High-purity reagent delivery tube: In the laboratory and pharmaceutical factory, PTFE bellows is used to deliver high-purity reagents, and its non-adsorption avoids the decline of reagent purity and ensures the accuracy of experimental results.
All kinds of corrosive medium pipeline: whether it is strong acid, strong alkali or other corrosive solvents, PTFE bellows can provide safe and reliable way of transportation.
Wire and cable sheath and slot insulation tube: In the power industry, PTFE corrugated pipe is used as the sheath of the wire and cable to provide excellent electrical insulation and weather resistance, and extend the service life of the wire and cable; in the submersible motor and air conditioning harness components, As a slot insulation tube, protect the wire from environmental factors such as oil, water, dust, etc.
