How to choose the lining material of electromagnetic flowmeter correctly? Posted by : admin / Posted on : Aug 14， 2020

Based on experience, the guide method for selecting electromagnetic flowmeter lining materials is as follows:
1. Ordinary rubber
The operating temperature is 60℃, which is characterized by elasticity and good wear resistance. Generally used in areas such as urban water supply and drainage, the corrosion resistance is relatively poor.
2. Polytetrafluoroethylene, also called PTFE
One of the more commonly used lining materials, because of its stable chemical properties, it is generally used for sanitary liquids or strong corrosive liquids, such as concentrated acids and alkalis.
3. Polyperfluoroethylene propylene
This material is similar to PTFE, but its wear resistance is stronger than that of PTFE, and the maximum temperature of the medium can reach 100℃.
4. Polyfluoroethylene
It has similar characteristics with F4 material, but the temperature is slightly worse. Generally, the temperature of the medium does not exceed 80℃, which is cost-effective and lower in cost than F4 material.
5. Neoprene
It is characterized by good wear resistance and excellent elasticity. It is generally used in water supply and drainage, sewage treatment and other fields. The corrosion resistance is slightly poor, and its shortcomings are not resistant to oxidation.
6. Polyurethane rubber
It has excellent wear resistance, but it is insufficient for corrosiveness, and the temperature should not exceed 80℃. It is generally used in industrial and mining environments with high wear resistance, such as the measurement of media such as slurry and coal slurry.
