1. What is the end plate?
The main function of the end plate and the sealing plate on each side of the terminal block is to prevent the metal part of the terminal from being exposed.
In steel structures, the end plates are connected to the column flanges with high-strength bolts, often called end plate connections. The restraint of the end plate connection on the beam end can meet the requirements of rigid connection.
2. Introduction to pfa
PFA is fusible polytetrafluoroethylene. The English name of PFA is Polyfluoroalkoxy, and the Chinese name is: tetrafluoroethylene-perfluoroalkoxy vinyl ether copolymer (also known as: perfluoroalkylate, soluble polytetrafluoroethylene) Vinyl). 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: 2.13-2.167 g/cm3, molding shrinkage rate: 3.1-7.7%, molding temperature: 350-400℃.
Features and main uses of PFA: PFA is commonly known as fusible PTFE, and its various properties are the highest among fluoroplastics. It is widely used in the semiconductor industry, as well as medical, chemical anti-corrosion, automotive and other fields.
3. Introduction to the end plate of pfa heat exchanger
Name: pfa heat exchanger end plate, pfa round cake, PFA round rod, etc.;
Uses: Fusion welding of Teflon FEP heat exchangers and other products.

Five, common problems of pfa heat exchanger end plate:
1. PFA heat exchanger end plate production
The home of Miss Teflon tube is an industrial brand.
2. Main features of PFA heat exchanger
PFA heat exchanger has excellent corrosion resistance: F4 is a chemically inert material, except for elemental fluorine at high temperatures, molten alkali metals, chlorine trifluoride, uranium hexafluoride, perfluorinated kerosene, and can be used in all media Work in.
The PFA heat exchanger has good anti-scaling performance: the chemical inertness, surface smoothness, flexibility and high coefficient of expansion of the F4 tube make it difficult to scale on the heat transfer surface and ensure a relatively stable heat transfer coefficient;
PFA heat exchanger has a long life and low overall cost: PTFE does not contain photosensitive genes, so it has excellent resistance to atmospheric aging. In strong corrosive media, its service life is 20 to 30 times that of stainless steel.
The heat transfer performance of the PFA heat exchanger is good: due to the small diameter of the pipe, no temperature gradient, and the thin-walled pipe, it overcomes the shortcomings of low thermal conductivity of PTFE materials, and its total heat transfer coefficient can reach 200-350 ( W/m2.K)

3. Connection structure of heat exchanger tube and end plate
Heat exchanger tubes and end plates. The end plates are provided with heat exchanger tube mounting holes, and an intermediate connecting sleeve is arranged between the heat exchanger tubes and the end plates. The front end of the intermediate connecting sleeve enters the heat exchanger tube mounting holes , The middle connecting sleeve and the heat exchanger tube mounting hole are connected through the external thread provided at the front end of the middle connecting sleeve and the internal thread provided on the wall of the heat exchanger tube mounting hole, and the end of the heat exchanger tube enters the middle In the inner hole of the connecting sleeve, the heat exchanger tube and the intermediate connecting sleeve are connected through 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 joints of the heat exchanger tube mounting hole, the intermediate connecting sleeve and the heat exchanger tube can all adopt standardized processing, which is easy for mass production and assembly. Simple, fast, and highly reliable.
Six, the use of pfa heat exchanger end plate:
PFA heat exchange equipment is also called plastic king heat exchanger or F4 heat exchanger. Its super anti-corrosion and anti-aging performance makes it widely used in chemical industry, pickling, electroplating, medicine, anodizing and other industries. At the same time, due to its resistance Excellent temperature performance, suitable for both steam heating and hot water heating.
Miss Teflon tube home: Shenzhen DanKai Technology Co., Ltd. (ShenZhen DanKai Technology Co.,ltd.), whose predecessor was Dongguan DanKai Insulation Material Co., Ltd.
