What is the 1. end plate?
The end plate and the sealing plate on each side of the terminal block are mainly used to prevent the metal part of the terminal from being exposed.
In steel structures, the end plate is connected to the column flange with high-strength bolts, often referred to as the end plate connection. The end plate connection can meet the requirements of rigid connection.
Introduction of 2. pfa
Pfa is meltable polytetrafluoroethylene, the English name of PFA is: Polyfluoroalkoxy, and the Chinese name is: tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer (also known as perfluoroalkylate, soluble polytetrafluoroethylene). The chemical properties of PFA FEP PTFE are similar, but FEP can only be used below 200 degrees, and PTFE cannot be injection molded. Specific gravity: 2.13-2.167g/cm3, molding shrinkage: 3.1-7.7%, molding temperature: 350-400 ℃.
The characteristics and main uses of PFA: PFA is commonly known as meltable PTFE, and various properties are the crown of fluorine plastics. Widely used in the semiconductor industry, as well as medical, chemical anti-corrosion, automotive and other fields.

2. Main features of PFA heat exchanger
PFA heat exchanger has excellent corrosion resistance: F4 is a chemically inert material, in addition to high temperature element fluorine, molten alkali metal, chlorine trifluoride, uranium hexafluoride, perfluorinated kerosene, can work in all media.
PFA heat exchanger anti-fouling: F4 tube chemical inertness, surface smoothness, bending and high expansion coefficient, so that the heat transfer surface is difficult to scale, to ensure a relatively stable heat transfer coefficient;
PFA heat exchanger has a long life and low comprehensive cost: PTFE does not contain photosensitive genes, so it has excellent resistance to atmospheric aging. Its service life is 20 to 30 times that of stainless steel in strong corrosive medium.
PFA heat exchanger has good heat transfer performance: due to the small tube diameter, no temperature gradient, and thin-walled tube, it overcomes the shortcomings of low thermal conductivity of PTFE material, so that the total heat transfer coefficient can reach 200-350(W/m2.K)

3. Heat exchanger tube and end plate connection structure
The heat exchanger tube, the end plate, the end plate is provided with a heat exchanger tube mounting hole, an intermediate connecting sleeve is provided between the heat exchanger tube and the end plate, the front end of the intermediate connecting sleeve enters the heat exchanger tube mounting hole, the intermediate connecting sleeve and the heat exchanger tube mounting hole are connected by an external thread provided at the front end of the intermediate connecting sleeve and an internal thread provided on the wall of the heat exchanger tube mounting hole, and the end of the heat exchanger tube enters the inner hole, the heat exchanger tube and the intermediate connecting sleeve are connected by an external thread provided on the heat exchanger tube and an internal thread provided on the inner hole wall of the intermediate connecting sleeve. The utility model can realize the quick connection between the heat exchanger tube and the end plate. The connections of the heat exchanger tube mounting hole, the intermediate connecting sleeve, and the heat exchanger tube can all be standardized and processed, which is easy to mass produce and simple to assemble. Fast and reliable.
6. pfa heat exchanger end plate uses:
PFA heat exchanger is also known as the plastic king heat exchanger or F4 heat exchanger, super corrosion resistance and anti aging performance makes it widely used in chemical industry, pickling, electroplating, medicine, anodizing and other industries, at the same time, because of its excellent temperature resistance, not only suitable for steam heating, but also suitable for hot water heating.
