1. Application of PTFE lined anti-corrosion thermistor

Adopting new anti-corrosion materials and coated with polytetrafluoroethylene F46, it is suitable for temperature measurement in various corrosive media in the petrochemical industry. It is a specialized temperature measuring instrument for the chlor alkali industry.

2. Characteristics of PTFE lined anti-corrosion thermistor

1. The anti-corrosion thermal resistor adopts a multi-layer anti-corrosion structure (the anti-corrosion layer of the anti-corrosion thermal resistor is usually a thick walled 316L or 304L steel pipe with an integral sintered polytetrafluoroethylene layer and wear-resistant anti-corrosion layer), and the anti-corrosion effect and service life have been verified by many domestic enterprises through long-term use.

2. Our company uses advanced domestic sintering technology to sinter the polytetrafluoroethylene anti-corrosion layer of the anti-corrosion thermistor, which solves the problem of joint leakage that cannot be avoided by other manufacturing processes. The application of this technology has enabled our company's anti-corrosion thermal resistors and other anti-corrosion products to have an average service life of over one year (in an environment without significant wear and tear).

3. At the site of use, there is often severe erosion of the anti-corrosion layer of the thermal resistor by high flow rate measured medium particles. Our company's anti-corrosion thermal resistor has a layer of wear-resistant material outside the anti-corrosion layer, which can effectively extend the service life of the anti-corrosion layer by 8-10 times in environments with erosion, unlike other similar anti-corrosion thermal resistors in China.

4. All anti-corrosion thermal resistors use domestically good components, and the entire product has stable and reliable performance. Its service life is several times longer than that of similar anti-corrosion thermal resistors in China, and it can work for a long time in the temperature range of ≤ 220 ℃.
