Preparation and chemical performance requirements for steel-lined PTFE tubes before purchase


The steel-lined PTFE tube is a tube made of steel-lined PTFE, and this type of tube is called a steel-lined PTFE tube. Moreover, based on some of its characteristics, it is widely used in some industries and fields. Therefore, in the future, the product will be familiar and understood in the future, so as to realize the correct and rational use and full utilization of the product.


1. When the steel-lined PTFE tube is purchased, is there any relevant factor for consideration? Do you want to pay attention?

The purchase of steel-lined PTFE tubes is an important task, so it should not be taken lightly and sloppy. All the factors related to product purchase are important considerations, there is no distinction between them, so there is no need to compare them, but also pay attention to them and take them seriously and important considerations, in order to avoid wrong choices in this product. The purchase.


2. Does the steel-lined PTFE tube have to be prepared before purchase?

From a professional point of view, the steel-lined PTFE tube should be prepared before the product is purchased, so that this work can be carried out smoothly and the right product can be selected. In the specific preparation work, the first is to have a clear understanding of the product use environment and use requirements, and the second is to know the specific information of the product and the manufacturer, such as product origin, parameters, size, price and quality, and after-sales service of the product. These can be compared and comprehensively considered.


3. Is the application of steel-lined PTFE pipes in the chemical industry extensive? What good chemical properties should it have?

Steel-lined PTFE pipes are widely used in the chemical industry. They are mainly used for their anti-corrosion properties. Moreover, the thickness of the lining is 2-5 mm. As long as it is used normally and regulated, the product can have a long service life and can be used for several years.


The steel-lined PTFE tube has good chemical properties. Its specific performance is: it has good aging resistance, good radiation resistance and low permeability. Even if it is exposed to the atmosphere for a long time, the performance of the tube can not be maintained. change. It should have good acid and alkali resistance, insoluble in strong acids, strong bases and organic solvents, and resistant to strong oxidants. In addition, its oxygen limit index should be below 90.


4. Can a steel-lined PTFE tube be used to deliver sulfur trioxide gas?

The steel-lined PTFE tube has good corrosion resistance, so it can be used to transport sulfur trioxide gas. However, it has a temperature range of use and is -29 ° C - 200 ° C. Also, a steel-lined PTFE tube manufactured by a molding process is used because it can function as a
