PTFE pipe The main cause of damage is wear. The wear is mainly concentrated on the change of fluid such as three-way, four-way and elbow, and the straight pipe 20mm~1000mm downstream of the installed valve (ball valve and butterfly valve are more serious). The fluid is reoriented due to the opening and closing of the valve, which causes the fluid to locally flush the pipe wall, resulting in wear and damage, thus damaging the pipe. Secondly, the actual operating temperature is higher than the temperature of the PTFE pipe with the selected lining steel, which will cause the lining layer to fall off and shrink, thus blocking the passage of the pipe, increasing the flow resistance, and affecting the passage of materials. The pipe manufacturer will cause quality problems and damage the pipe.

According to the local professional manufacturer of lining plastic pipe products, lining PTFE pipes have good resistance to water vapor penetration and seepage, chemical resistance and aging resistance, and are ideal insulation and anti-corrosion materials. For plastic pipes with lining, it is important that they can inhibit the corrosion that is easy to occur under different conditions, especially in the case of insufficient general sterilization. It is especially suitable for preserving fiber and wood with mineral oil and tannic acid, and for biological samples of formaldehyde, toluene, butyl p-hydroxybenzoate, nitrofuran derivatives or balsam resin.


Steel lined PTFE pipe has high impact resistance. Rubber will deform under impact, absorb kinetic energy of particles, and then return a large part of energy to particles in the form of rebound, thus reducing impact force and greatly improving service life. The rubber lining can be prepared according to the wear resistance requirements, and is suitable for use in high wear environment. Its wear resistance is more than 20 times that of steel pipes, more than 4 times that of ceramics, and more than 7 times that of similar rubber lined pipes. At the same time, the selection of lining plastic pipe is not only suitable for various pressure requirements, but also plays a role in protecting the colloidal lining.


Polytetrafluoroethylene pipe is a common carbon steel pipe as the base material, and lined with thermoplastic polytetrafluoroethylene plastic with excellent chemical stability, and processed through the molding process. Steel lined PTFE pipeline is an ideal pipeline for transporting high temperature and strong corrosive media (such as strong acid, strong alkali, industrial salt and strong corrosive gas). They are widely used in the chemical, metallurgical, pharmaceutical, electric power, pesticide, mining and papermaking industries.
