1. FEP bellows common specifications
1. Name: FEP corrugated pipe, also known as 200-degree high-temperature pipe, transparent Teflon corrugated pipe or Teflon corrugated pipe;
Common specifications: (unit: mm) other specifications can be customized according to demand
Metric: the outer diameter includes 6mm, 8mm, 10mm, 16mm, 20mm, 25mm, 38mm and 60mm;
Imperial: including 1/8 inch, 1/4 inch, 3/8 inch, 1/2 inch, 3/4 inch and 1 inch specifications.
2. FEP bellows use
Electronic insulation material: FEP tube is often used as the insulation layer of wire and cable because of its excellent insulation characteristics.
Chemical fluid transport: FEP tubes have excellent resistance to most chemicals and are suitable for the transport of chemical fluids.
Groundwater sampling pipeline: In groundwater analysis, FEP pipes are used as pipelines for conveying water due to their high purity to ensure that the sampling process does not contaminate the measured object, thereby maintaining the accuracy of the measurement results.
Heat-shrinkable tubing and paint delivery: FEP is also used to produce heat-shrinkable tubing and is used as a material for paint delivery rollers in printing machinery. Its high surface quality can effectively prevent the adhesion, contamination and discoloration of the material to be printed.
Medical catheters and endoscopes: In the medical field, FEP tubes are often used to make catheters and endoscopy tools. At the same time, they can effectively prevent liquid from being contaminated during infusion, have good biocompatibility, and can be sterilized by regular methods.
Heat exchanger components: FEP tubes are widely used in the manufacture of heat exchangers because of their long life and simple welding characteristics.
Water treatment system: Because the FEP tube has excellent UV resistance and high transmission rate, it has become an ideal choice for UV spiral tubes in water purification systems, which can effectively kill bacteria in the water while maintaining the stability of the pipeline itself.
3. the life of transparent Teflon FEP bellows
The service life of the transparent Teflon FEP bellows refers to the minimum time or number of cycles that can maintain normal operation under normal working conditions. In the application of elastic sealing system, it is of great significance to determine its service life because it is often subjected to cyclic load and large displacement. According to the different application scenarios of the transparent Teflon bellows, the requirements for its service life are also different.
(1) When compensating for the position deviation caused by installation in the pipeline system, the service life of the transparent Teflon bellows only needs a few times to meet the requirements.
(2) In the constant temperature controller with high switching frequency, the service life of the transparent Teflon bellows needs to reach 10000 times to meet the needs of long-term use.
(3) When used as the vacuum seal of the vacuum switch, the service life of the transparent Teflon bellows needs to reach 30000 times to ensure its normal operation and sealing performance.
