Polytetrafluoroethylene hose is a common pipe fitting in industry. The temperature is between – 20 ° C and + 180 ° C. It is used in pipelines to solve the problems of vibration, displacement, emission and thermal expansion and contraction compensation. The material is made of pure PTFE tube, which is processed into spiral shape by heat setting the die. At present, * the small diameter can be DN15 and the diameter can be DN250. Generally, the diameter below DN50 is made of dispersed PTFE, while the diameter is greater than DN50. It is made of wound PTFE tube with a thickness of about 1? 3mm, the connection method is flange type, the screws are symmetrically tightened slowly, there is crimping type, align and compress, and then fix the pin.

Application scope of PTFE hose: the inner wall of the product is smooth, with the characteristics of high temperature resistance, chemical corrosion resistance and non adhesion of viscous substances. The conductive / insulating and food grade (in line with FDA standards) inner layer can be customized. It is suitable for conveying compressed air, esters (such as grease), viscous substances (such as glue), corrosive chemicals and oil at high temperature.
