Description

Introduction to heat tracing sampling compound piping


The heat tracing and sampling composite cable is an important part in the monitoring system. It is composed of a group of corrosion-resistant and high-performance resin conduits, high temperature constant power electrical belt or self-limiting electrical belt and compensation cable. It is added with imported raw material insulation layer and coated with polyethylene or PVC sheathing. The constant power electric belt adopts platinum resistance temperature probe to control the temperature. The automatic temperature limiting function of the self-limiting temperature electric belt can ensure that a certain temperature is maintained in the sampling tube, so as to ensure that the collected samples are consistent with the initial value as far as possible, and finally ensure the continuity of the monitoring system. Collect sample gas accurately. According to different ambient temperature, can use appropriate tracking belt, as well as compensation line, power line, etc. Can also be added according to user requirements.




Technical parameters of heat tracing and sampling composite cable

5 Insulation layer: high temperature resistant rock wool, glass silk wool.


6. Sheath layer: black PVC/PVC/polyethylene wear resistant layer, flame retardant/waterproof/high temperature resistance/corrosion resistance.


Installation rules of heat tracing sampling compound pipe


Electrical index

1. Rated voltage: 220VAC.

2. Self-limiting temperature pipeline z.u large heating length 100 ~ 120m.

3. The self-limiting temperature pipeline is equipped with a circuit breaker with a current value of 30A.

4. One circuit of the heat tracing system.

Thermal index

1. At -20℃ ambient temperature and 15m/s wind speed, keep the temperature in the pipe at 40 ~ 50℃.

2. The sample tube can resist the corrosion of various acid and alkali media, with compressive strength of 1.0Mpa and no leakage.

3. The sample tube can work for a long time under the temperature of < 200℃.

Installation index

1. The z.u small curvature radius of the composite pipe is 0.5m.

2.z.u low installation temperature -20℃ (take appropriate measures when -30℃ ~ -40℃).

3.z.u small fixed distance: 2m vertical direction, 4m horizontal direction.


Installation precautions of heat tracing sampling compound pipe


It is strictly prohibited to twist and drag on the ground during the construction process. Only after the contact is installed, it is allowed to remove the tube head sheath. The end of the tracking belt should be closed to prevent the two lines of the tracking belt from short-circuiting and burning the tracking belt. The shield layer of the tracking belt shall be grounded to prevent electric shock. Special intermediate junction boxes or power junction boxes should be used at one end of the power supply to avoid potential accidents. Install the leakage protector for the distribution switch.
