The Application area and Installation methods of PTFE assembly hose

March 08 22:45 2021

The installation of the joint PTFE Tube is called PTFE assembly hose, this assembly hose is generally made of 100% pure PTFE resin tube and 304 or 316 stainless steel braided and various types of joint composition can also be customized into different lengths.

It is characterized by high temperature and high-pressure resistance, corrosion resistance and aging resistance, and is generally connected to machinery and equipment.

Application area

Polytetrafluoroethylene (PTFE) hose assembly has many advantages, but its high cost limits its application in a wider range of fields. At present, polytetrafluoroethylene hose assemblies are mainly used in various hydraulic, pneumatic, fuel, power and servo mechanisms in aviation and aerospace fields with high requirements for product performance and quality. As a flexible pipeline for medium transmission, PTFE hose assemblies have been successfully used in various types of aircraft and launch vehicles. For example, some western developed countries led by the United States began to develop PTFE hose assemblies as early as the 1950s, and began to develop them in the 1920s Polytetrafluoroethylene (ptfe) hose assemblies are widely used in the high-end aerospace field in the 1960s. As a high-tech product, ptfe hose assemblies are attracting more and more attention in various application fields and playing an increasingly important role.

Product features

The PTFE Hose supplier made it with lighter weight, wider temperature range (-55 ~ 232 C), higher chemical stability, corrosion resistance, aging resistance and less flow resistance (1/2 to 1/3 of metal hose) compared with rubber tube and metal bellows. Compared with the same rubber hose, it has the advantages of small radial dimension, long service life and high reliability. At the same time, steel wire reinforced PTFE hose assembly has many advantages, such as vibration absorption, bending fatigue resistance and so on.

Although polytetrafluoroethylene hose assembly has many advantages mentioned above, it also has higher requirements for installation. When the bending radius is too small, it will cause the tube body to collapse and form damage at the bending place; in addition, the distortion of the tube body during installation will also reduce the reinforcement effect of the hose, which will lead to the decline of the service life of the product and even cause failure. Therefore, in the process of replacing rubber hose and metal bellows with a polytetrafluoroethylene hose assembly, attention should be paid to the installation requirements of products from two aspects of design and use.

Install ptfe hose fittings

PTFE hoses fittings are divided into many kinds, different fittings have different installation methods, In addition, the inner diameter of the hose should be appropriate. If the pipe diameter is too small, it will increase the flow rate of the medium in the pipeline, make the system heat, reduce the efficiency, and produce too much pressure drop, which will affect the performance of the whole system. So generally, the ptfe hose manufacturer will write the characteristics and detailed installation introduction of each type of connector:

Installation method:

1. First of all, the end face of the pipe is cut flat to ensure that the pipe is O shaped. It is best to use special tools, otherwise, it will leak;2. First, put the nut into the pipe, and then insert the pipe into the joint core rod and tighten it.

Sanitary joints:

stainless steel quick-release joints are called sanitary joints, sanitary joints, stainless steel unions, food unions, etc. This kind of joints are made of imported SUS304, 316L material, which can meet the requirements of food, beverage, dairy products, cosmetics, and biological products. Special requirements for pharmaceuticals, fine chemicals and various media. This product has been processed by high-end polishing process, the surface is smooth, seamless, and the handicraft channel is automatically drained. The manufacturing strictly implements the standards ISO, DIN, IDF, SMS, and and GMP Food Sanitation 3A The standard, designed with the latest computer three-dimensional dimensional accuracy, meets the domestic sanitary food requirements.

Installation method:

1. Prepare the processed pipe first and cut it to the length the buyer need; 2. Put the sleeve into the pipe, and then put the pipe on the joint core rod; 3. After the pipe is put in, put the sleeve The tube is pushed out to cover the pipe; 4. Use the machine to tightly press the sleeve on the joint. 5. The other end of the joint is also crimped like this, and finally the two joints are connected with a ferrule, and the sanitary joint assembly tube is assembled.
