PTFE tube manufacturer selection requirements and determinants of pressure resistance

- Dec 06, 2018-

The PTFE tube is a kind of tube made of PTFE material, and it belongs to the plastic tube. It needs to be familiar and understood to realize the correct and reasonable use of this kind of tube. Good use effect and use purpose, not waste of product.


1. Does the manufacturer of PTFE tubes have any requirements for selection?

A manufacturer of PTFE tubes, which is an important aspect of PTFE tubes, and it is an aspect that cannot be ignored in the purchase of this product. Therefore, based on this, it is necessary to seriously consider the specific aspect of PTFE tubes. Pay enough attention to choose the right manufacturer. In the choice of the manufacturer, it is required to select professional and regular manufacturers, which can ensure the quality of the products and the good performance of the products.


2. What is the expansion coefficient of a PTFE tube?

The expansion coefficient of the PTFE tube has different expansion coefficients at different temperatures. If the temperature is in the range of 25 to 250 degrees Celsius, the expansion coefficient of the PTFE tube ranges from 10 to 12×10-5/°C. The specific value is also determined by the specific temperature. In addition, it is also necessary to know that the temperature range of the PTFE tube is -60 ° C - 260 ° C, and the positive and negative pressures that can be withstand are 1.6 MPa and 77 KPa, and at high temperatures, highly corrosive substances can be transported.


3. What is the size of the PTFE tube pressure? What are the production equipment?

The pressure resistance of the PTFE tube, according to the professional introduction of this aspect, is determined by the wall thickness of the tube, not by the diameter of the tube, and the manufacturer will mark it on the tube. If the tube is marked with xxxMPa The words indicate the pressure resistance of the PTFE tube. The production equipment for this type of pipe mainly uses two types of equipment, basic equipment and molding equipment. In addition, there may be other equipment.


4. Is there a difference between the PTFE tube and the trifluoro tube?

Comparing the PTFE tube with the trifluoro tube, it can be concluded that there are many differences between the two tubes. First, in terms of corrosion resistance, the PTFE tube is better than the trifluoro tube, but the hardness of the trifluoro tube. It has high strength and good low temperature resistance; in terms of price, it is a trifluorotube higher than a tetrafluorotube. However, the two pipes have the same point, that is, they have good corrosion resistance and can be used to transport some corrosive
