1. What is a PFA tube?
PFA tubing is a high-performance plastic tubing made of perfluoroalkoxy resin, or PFA for short. It has an extremely high temperature range (-80 to +260), excellent chemical stability, low coefficient of friction and excellent electrical insulating properties. PFA tubing can maintain its physical and mechanical properties in extreme environments, is not easy to be corroded, and the inner wall is smooth, does not adhere to the medium, especially suitable for the transmission of high-purity chemicals, strong acid and alkali solutions and high-temperature fluids. Because of its excellent characteristics, it is widely used in pipeline systems and wire and cable sheaths in semiconductor manufacturing, chemical industry, pharmaceutical, food processing and other fields.
2. What is a bellows?
Bellows is an elastic element formed by a special process, and its structure is characterized by continuous or intermittent corrugations inside. There are various corrugated pipe materials, including metal (such as stainless steel, copper, etc.), non-metal (such as rubber, plastic such as PVC, PE, PTFE, PFA, etc.). The bellows can absorb axial, lateral or angular displacement within a certain range by using its own elasticity and deformation ability, and can play a role in vibration and noise reduction, and compensate for thermal expansion and contraction. According to different uses, bellows can be divided into various types such as pressure bellows, vacuum bellows, telescopic bellows, and wear-resistant bellows.
3. What is the purpose of the bellows?
1.In the piping system, the bellows is used to connect the pipelines between the equipment, effectively compensate for the length change caused by temperature changes or installation errors, and ensure the normal operation of the piping system.
2.In mechanical equipment, as a flexible connector, it can reduce vibration transmission and protect equipment from impact damage, such as bellows in automobile exhaust systems.
3.In construction engineering, the bellows is used as a perforated pipe for the prestressed tendons to ensure that the prestressed tendons will not be polluted when the concrete is poured, and at the same time facilitate the tensioning operation.
4.In electrical engineering, the bellows is used as a protective jacket for wires and cables to prevent damage to cables caused by external environmental factors, and to enhance safety and service life.
4. Which is better, bellows or PFA pipe?
The two are not comparable, because they do not belong to the same dimension comparison.
Bellows usually refers to a pipe made of metal or non-metallic materials with a continuous annular corrugated structure, which is a pipe with a corrugated structure form. The PFA pipe, which is made of PFA as the main material, is a PFA pipe.
Bellows are commonly classified according to fluorine materials: PTFE bellows, PFA bellows, and FEP bellows.
PFA tubes are classified according to their structural form: straight PFA tubes, corrugated PFA tubes, and PFA tubes with special shapes (such as elbows, tees, reducers, etc.).
Therefore, because bellows and PFA pipes do not belong to the same dimension, there is no significance of good and bad comparison.
