Instrumentation insulation and protection

In general, the temperature of the medium in the instrument pipeline should be between 20-80 degrees, and the temperature in the instrument incubator should be maintained between 15-20 degrees. In order to compensate for the heat emitted and lost by the instrument pipelines and containers and instrument incubators, insulation heat tracing measures must be taken.

At present, there are mainly two kinds of heat-retaining heat tracing measures, one is traditional steam and hot water heat tracing. The other is electric heat tracing. In recent years, with the maturation of electric heat tracing technology and its unique advantages, it will gradually become a new generation of heat preservation methods that replace steam and hot water heating. The steam heating of the instrument incubator is mainly composed of a box body, a lined insulation material, a transmitter bracket, and a U-shaped steam radiator. In order to facilitate the daily maintenance, the observation window is often provided on the door of the box, and the box top may be provided with an opening for inserting bimetal without temperature.

The electric heating of the instrument heat preservation box generally adopts the electric heating tube, while the electric heat tracing of the instrument pipeline adopts the electric heating belt. The electric heating tube is the outer shell of the seamless steel tube, and the resistance wire is filled in and filled with the magnesium oxide powder insulation. The electric heat tracing has heat. The high suburban rate, energy saving, simple design, convenient construction and installation, no pollution, long service life, and the advantages of remote control and automatic control. It is the technological development direction to replace steam and hot water heating. It has been widely used in industrial and mining enterprises in various industries.
