How does the PFA tube press the card edge? Why should it be pressed?

What is the PFA tube manufacturing process?

The manufacturing process of PFA tube mainly includes three main steps: raw material pretreatment, melt extrusion and cooling. First, the high purity PFA resin particles are dried and dehumidified to ensure stable material properties. Then, through a professionally designed PFA extruder, the pre-treated resin particles are fed into a heated screw, melted at high temperatures and homogenized by the shear force of the screw. Then, the PFA material in the molten state is moulded to the desired pipe size and quickly cooled and solidified in a continuous cooling system to obtain a PFA pipe with smooth internal and external surfaces, accurate dimensions and excellent chemical and heat resistance.


How to press the PFA tube edge?

The "clamping edge" of PFA pipe usually refers to the special processing of the end of the pipe in order to facilitate the connection or sealing with other components. The specific operation may include the following steps:

  1. First, cut the triflure PFA pipe to a suitable length according to the connection requirements, and use special tools or equipment to chamfer the pipe mouth to remove burr and ensure smooth edges.

  2. For the need to install joints or flanges, the pipe is inserted into the special metal clip or plastic clip ring, through cold extrusion or heating softening after extrusion, so that the outer wall of the PFA pipe is close to the internal structure of the clip, forming a firm and tight mechanical connection.

  3. Another possibility is to use a specific clamp or flange with insert, by slightly folding or deforming the PFA tube end to increase the contact area and tightness between the connector and ensure no leakage connection.

What is the significance of PFA management and suppression?

  1. Ensure the tightness of the pipe. The use of stainless steel clamps to suppress the PFA pipe can isolate the medium upstream and downstream of the pipeline, prevent the leakage of the medium or the leakage problem at the connection of the pipeline, and ensure the safety and reliability of the medium transportation.

  2. Improve the pressure bearing capacity of the pipeline. The Triflure PFA pipeline is subjected to the force of the internal medium during use, and the connection between the pipeline and the clamp after being compressed generates greater friction, which can effectively enhance the bearing capacity and tensile strength of the pipeline.

  3. Ensure the stability of the pipeline. PFA pipes are often used for medium transportation under high temperature, high pressure and corrosive conditions, so it is necessary to ensure the stability and integrity of the pipeline. By pressing, problems such as displacement, sliding and loosening can be effectively prevented at the joint of the pipeline to ensure long-term stable operation of the pipeline
