H serial non-fixed flange’s protective tube is setting outside the temperature measurement component when thermocouple and resistor is working, and it has the anti-corrosion effect and defends against agent’s pressure, which makes the output of measurement component precisely reflect the temperature.

It has following features:

1. According to IEC international standard design

2. High concentricity and deep hole processing. Anti-high pressure, temperature and liquid speed.

3. Can be manufactured and installed with the equipment at the same time;

4. Different pressure demands to meet different environments and industries.

5. According to customers’ need, we can provide extra long protective tube more than 1.5 meter long.

The protection tube can be welded directly to the field device or soldered to a self-contained flange to form a flange-type protection tube.

1) combination form

2）Size

3) protection of pipe materials and the use of temperature
