How to buy and bond PTFE tube

- Nov 22, 2018 -

A PTFE tube, which is a tube made by processing with PTFE material, is a plastic tube and is widely used from the current point of view. Therefore, it needs to be fully familiar and understood so that it can be used correctly and reasonably. A tube that, in turn, allows the product to be fully utilized and avoids waste.


1. How to choose the PTFE tube and how to purchase it?

From the professional point of view, this is an important task that needs to be taken seriously and carried out so that the right product can be selected and the wrong choice can be avoided, because if the wrong choice occurs, it will affect The normal use of the product and its use effect may even result in waste and economic loss due to the inability to use the product. In consideration, all relevant factors should be taken into consideration in order to have accurate judgments and correct selection of results.


For PTFE tubes, there are mainly three ways to purchase products. One is to directly purchase the manufacturers, the other is to purchase the products through agents, and the third is to do this work on their industry websites. However, what you need to know is that no matter which way you choose, you need to know the specific information of the product and the manufacturer. Otherwise, you cannot purchase the product.


2. Is the steel-lined PTFE tube a PTFE tube?

Steel-lined PTFE tube, which is mainly used for medium conveying work, has good temperature resistance and corrosion resistance, and can withstand nitric acid, sulfuric acid, hydrofluoric acid, phosgene, chlorine gas, aqua regia, mixed acid, bromide, etc. Corrosion of these media is an ideal transport tool and can be used at high temperatures for a long time. This kind of pipe, in terms of properties, is one of the PTFE pipes, but it is not equivalent to the PTFE pipe. Therefore, it cannot be considered that the steel-lined PTFE pipe is a PTFE pipe.


3. How many degrees of high temperature can the PTFE tube withstand? How to connect?

The upper limit of the temperature of the PTFE tube is 260 degrees, because the melting point of the material of polyethylene tetrafluoroethylene is 327 degrees, and the softening phenomenon occurs after more than 260 degrees, but under certain working conditions, 300 degrees High temperatures can also withstand. For the connection of the PTFE tube, the glue cannot be used, because any glue can not be firmly bonded and can only be sintered. If it is connected to a metal, the metal surface needs to be sanded or pickled, and the metal surface is dried before the bonding operation can be performed.
