Benefits of steel-lined PTFE materials and comparison of Polytetrafluoroethylene(PTFE) lining

- May 25, 2019-

Polytetrafluoroethylene(PTFE) lining, which is a kind of pipe that uses two materials, and combines the steel pipe and the PTFE pipe to exert their respective advantages, so it can be used in some occasions and fields. Therefore, based on this, it is necessary to have a correct understanding and comprehensive understanding of the polytetrafluoroethylene(PTFE) lining in order to achieve the purpose of rational use of the product.


1. Can Polytetrafluoroethylene(PTFE) lining be used to transport highly corrosive media?

Polytetrafluoroethylene(PTFE) lining, polytetrafluoroethylene tubing and fittings, they have very good high temperature and corrosion resistance, because they can withstand nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine, aqua regia, mixed acid These organic solvents, such as bromide, are strongly corroded and can be used as a conveyor device. Therefore, based on this, the polytetrafluoroethylene(PTFE) lining can be used to transport a highly corrosive medium and has a good conveying effect.


2. Is steel lining PTFE a good material for use on pipes?

Steel-lined PTFE, which is used in pipes, can bring some benefits. It can get good corrosion resistance and can resist corrosion of various acids, alkalis and salts, except for molten alkali and molten salt. These two are outside. Therefore, the obtained pipe can be used in some corrosive environments, and the pipe can fully exert its characteristics while achieving the purpose of use.


3. Lining plastic pipe and polytetrafluoroethylene(PTFE) lining, which one is larger?

Lining plastic pipe, which is a kind of pipe with plastic pipe lined on the outside, which is made of steel lining PO pipe, steel lining PP pipe and steel lining PTFE pipe in specific types, so from this definition The polytetrafluoroethylene(PTFE) lininge is one of the lining plastic tubes. Therefore, the range of the lining plastic tube is larger than that of the polytetrafluoroethylene(PTFE) lining.


4. Is there a difference between a steel-lined pope tube and a polytetrafluoroethylene(PTFE) lining? What is the thickness range and applicable temperature of the polytetrafluoroethylene(PTFE) lining?

Steel-lined pope pipe and polytetrafluoroethylene(PTFE) lining, from the professional point of view, the two pipes are obviously different, mainly in the material composition and pipe properties, the plastic materials used in their lining are not the same, although outside They are all steel pipes. The thickness range of the polytetrafluoroethylene(PTFE) lining is 3-12 mm, and the applicable temperature is -100 to 250
