In the decades of production and practical use, it has been found that factors affecting temperature, pressure and medium will affect its service life and stable performance. High quality materials and advanced manufacturing methods are the quality assurance of PTFE Lining Products.

The main reason for the damage of PTFE Pipe is wear. The wear is mainly concentrated on the change of fluid such as tee, cross, elbow, etc., as well as the 20mm ~ 1000mm straight pipe 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, resulting in local flushing of the pipe wall by the fluid, resulting in wear and damage, thus damaging the pipe. Secondly, the actual use temperature is higher than that of the selected steel lined PTFE pipe, which will cause the lining layer to fall off and contract, thus blocking the pipe through, increasing the flow resistance and affecting the material through. The pipe manufacturer will cause quality problems and damage the pipe.

According to the local professional manufacturer of lined plastic pipe products, the lined PTFE pipe has good water vapor permeability and permeability resistance, chemical resistance and aging resistance, and is an ideal insulation and anti-corrosion material. For lined plastic pipes, it is important that they can inhibit the corrosion that is easy to occur under different conditions, especially in the case of insufficient sterilization. It is especially suitable for the preservation of fibers and wood with mineral oil, tannic acid, and biological samples of formaldehyde, toluene, butyl p-hydroxybenzoate, nitrofuran derivatives or balsam resins.

Steel lined PTFE pipe has high impact resistance. Rubber will deform under impact, absorb the kinetic energy of particles, and then return a large part of energy to particles in the form of rebound, thus reducing the impact force and greatly improving the service life. The rubber lining can be prepared according to the requirements of wear resistance and is suitable for use in high wear environment. Its wear resistance is more than 20 times of steel pipe, more than 4 times of ceramic, and more than 7 times of similar rubber lined pipe. At the same time, the selection of lined plastic pipe not only meets the needs of various pressures, but also plays a role in protecting the gel 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 by molding process. Steel lined PTFE pipeline is an ideal pipeline to transport high temperature and strong corrosive medium (such as strong acid, strong alkali, industrial salt and strong corrosive gas). They are widely used in chemical, metallurgical, pharmaceutical, electric power, pesticide, mining and papermaking industries.
